Newsletter: Coronavirus and Climate Change

Four Twenty Seven's monthly newsletter highlights recent developments on climate risk and resilience. This month we discuss the implications of the COVID-19 crisis for climate change and share a new Moody's report on scenario analysis.

COVID-19 and Climate: Multifaceted Impacts

427 Analysis - A Public Health Emergency with Dire Economic Consequences and Several Implications for Climate

The unprecedented global public health crisis from COVID-19 has led to fears of a global recession, but also presents a range of implications for climate change. While COVID-19’s immediate impacts include emissions reductions, the longer-term impacts on climate action and resilience-building are more complex. Likewise, COVID-19 may provide insight into how prepared communities are for the increasing frequency of disasters and how financial institutions can prepare for sudden disruptions. Four Twenty Seven's new analysis explores several of these impacts, outlining topics to watch as we strive to understand the long-term implications and ensure the safety of communities and businesses.

The analysis highlights that short-term emissions reductions may be followed by economic stimulus packages favoring polluting industries. Yet, as companies adapt to remote work, there is the potential for longer-term behavior shifts that help reduce emissions. Meanwhile, communities around the world face various levels of restrictions, with impacts on climate negotiations and research. The COVID-19 pandemic increases the risk of business disruptions and compounds the public health risks of extreme weather events, making businesses and communities more vulnerable to climate impacts. The crisis also underscores the need for preparedness. The ways policy-makers, businesses and individuals respond to today’s public health emergency and the resulting successes and failures may provide lessons for responding to other multifaceted disasters, applicable to extreme weather events and natural disasters.

Moody's on Climate Scenario Analysis

Using Scenario Analysis to Assess Credit Impact of Climate Risks

Climate-driven extreme weather events and the transition to a low-carbon economy are expected to have material impacts on companies, with increasing significance for credit analysis. However, both physical and transition risks have a wide range of potential outcomes. In its new report, Climate scenarios vital to assess credit impact of carbon transition, physical risks, Moody’s Investors Service describes a conceptual approach to scenario analysis, leveraging Four Twenty Seven’s methodology for physical risks.

The transition risk approach is to explore sector-specific credit implications for two IEA emissions scenarios. For physical risk scenarios Moody’s will use data from Four Twenty Seven to provide a uniform starting point from which to explore the range of credit implications of different climate hazards across sectors. Since the climate takes years to fully respond to greenhouse gases in the atmosphere, in the near-term the uncertainty in physical outcomes is not driven by policy changes, but rather by scientific uncertainty within the climate models. By grouping the outcomes of climate models within a single RCP into low, medium and high tiers one can explore the range of potential severity in climate hazards such as extreme temperature and precipitation.

RCP 8.5 - Still a Valid Possibility

Extracting the Scientific Uncertainties from the Policy Uncertainties

An article published in Nature last month sparked confusion about the legitimacy of Representative Concentration Pathway (RCP) 8.5, but there are compelling reasons RCP 8.5 remains an important part of scenario analysis. The study's authors explain that the initial design of RCP 8.5 was to capture growing rates of coal production in China. They assert that since the rate of coal production has actually slowed, it's not appropriate to continue using this scenario as the "business-usual" scenario and rather it should be considered a highly unlikely extreme scenario. However, the article focuses on the policy drivers, rather than the scientific drivers, of warming. The authors do not explore the physical phenomenon, such as sudden release of methane (a powerful greenhouse gas) due to thawing of permafrost. This is one of several tipping points that could lead to RCP 8.5 outcomes by 2100, independent of how coal production evolves.

While the initial design of RCP 8.5 was intended to capture growing rates of coal production, it doesn’t mean the scenario can’t be a stand-in for other sources of emissions that could quickly accelerate due to tipping points. Bob Kopp, a climate scientist at Rutgers University, has previously pointed out on Twitter that "from a climate science perspective, RCP 8.5 is very useful, since we would like to know how models simulate a 5C world.”

It's important to note that under any scenario, we are committed to a certain amount of physical climate impacts to mid-century, regardless of RCP scenario. Temperature outcomes don't differ significantly under different RCP scenarios until after mid-century. For longer-term projections it is valuable to model impacts under several scenarios, such as RCP 4.5, RCP 7 (forthcoming in the latest generation of climate models) and RCP 8.5.
New Survey on the Quality of Climate Risk Reporting

Climate Risk Disclosures Lack Transparency

Companies tend to disclose more details on their exposure to transition risk than physical risk and disclosures still lack transparency on which models and assumptions companies use to assess risk, according to the recent European Financial Reporting Advisory Group report on How to Improve Climate-related Reporting. The report highlights that when firms approach disclosures solely from a compliance perspective, they miss an opportunity to genuinely identify their risk and improve their resilience. It also identifies best practices and current maturity of disclosures in line with the Task Force on Climate-related Financial Disclosures (TCFD) and the EU Non-financial Reporting Directive's non-binding guidelines on climate risk. The Climate Disclosure Standards Board also released an EU Environmental Reporting Handbook sharing examples of environmental and climate disclosures under the EU Non-Financial Reporting Directive.
Regulatory Action & Oversight on Climate Risk Disclosure

Australia and UK Each Announce Plans for New Disclosure Regulation

The Australian Prudential Regulation Authority joins regulators calling for climate stress tests, announcing that its banks will be required to conduct stress tests for climate risks under several scenarios. After a devastating bushfire season followed by damaging floods, regulators are increasing the urgency around implementing stress tests and plan to release more details within the next few weeks. Earlier this month the UK's Department for Work and Pensions announced its consideration of an amendment to the Pension Schemes Bill that would mandate that pensions disclose their approaches to climate change in line with the TCFD.

European Union Opens Public Consultation on Non-Financial Reporting Directive

Meanwhile the European Commission opened a public consultation on updates to its Non-Financial Reporting Directive. This is part of the EU's commitment to increasing sustainable investment in Europe under the European Green New Deal and the review will explore how adjusting disclosure guidelines can support these goals. Feedback is due by April 28.

UK's Financial Reporting Council to Review Climate Disclosures & Audits

Amid concerns that firms are not complying with increased regulations around climate risk disclosure, the UK's financial watch dog, the Financial Reporting Council, will review corporate disclosures and audits to ensure that they address reporting requirements. “Auditors have a responsibility to properly challenge management to assess and report the impact of climate change on their business,” FRC Chief Executive Jon Thompson said in a statement.
Financial Risks of Climate Change are Underpriced
Australia's bushfires are expected to reduce national GDP by 0.1-0.4 percentage points through this March. Meanwhile the UK confronts damaging floods, Europe had its warmest January on record and sea level rise threatens to inundate airports around the world. These are just a few of the many multifaceted impacts that climate change has on global economies. Recent commentaries published in Nature Energy discuss the global implications of climate change's potential impact on the energy sector, which drives much of the interconnected global economy. One commentary by UC Davis Professor Paul Griffin, highlights the particular exposure of this sector to physical climate risks, with fossil fuel infrastructure in the Gulf Coast and the exposure of California's utilities to wildfires, as noteworthy examples. Authors assert that if these risks continue to be underpriced, we risk a recession on par with the 2008 housing crisis.

Newsletter: Scenario Analysis for Physical Climate Risks

Four Twenty Seven's monthly newsletter highlights recent developments on climate risk and resilience. This month we feature a report on scenario analysis for physical climate risks, share technical elements of climate risk assessments and highlight new research on sea level rise.

In Focus: Scenario Analysis for
Physical Climate Risks

427 Report: Demystifying Scenario Analysis for Financial Stakeholders

Scenario analysis is an essential yet challenging component of understanding and preparing for the impacts of climate change on assets, markets and economies. Many climate impacts are already locked in to mid-century, so when focusing on the next few decades scenario analysis should focus on the scientific phenomenon driving uncertainty, rather than the climate policies which have a greater impact over the longer term. Four Twenty Seven's new report, Demystifying Climate Scenario Analysis for Financial Stakeholders, explores which impacts are already locked in, identifies how Representative Concentration Pathway (RCP) scenarios fit into the conversation, and describes an approach to setting up scenario analysis for near-term physical climate risks.
 
Our atmosphere will continue to warm for many decades even if we stop emitting carbon dioxide tomorrow.  The oceans will continue to rise, heat waves will become more severe and droughts will intensify. For example, the most water stressed areas  are anticipated to experience reductions in dry season rainfall equivalent to the two decades surrounding the American dust bowl. This report outlines an approach called percentile-based analysis, which allows users to explore the range of potential outcomes based on climate model outputs within a single RCP.

Technical Drivers of
Climate Risk Assessments

Leveraging the Cloud for Rapid Climate Risk Assessments

"Providing location-specific risk assessments requires accessing and processing the best climate data available. Climate data poses processing challenges due to the raw file size of climate model outputs, where a single file can be hundreds of megabytes or more, and an entire dataset can be anywhere from tens of terabytes to multiple petabytes." Four Twenty Seven Senior Data Analyst, Colin Gannon, writes about leveraging Amazon Web Services (AWS) for data storage and processing.

The Next Generation of Climate Models

Forty-nine modeling organizations are working on the next generation of climate models, known as Coupled Model Intercomparison Projects, or CMIP 6. Some of these models have already been released, but others are still forthcoming. CMIP 6 explores a larger range of potential futures and released models tend to project more warming than previous climate models. Although CMIP 6 is behind schedule, the Intergovernmental Panel on Climate Change's Sixth Assessment Report plans to incorporate these updated models into its analysis. 
Sea Level Rise - What's at Stake?

Global Vulnerability to Sea Level Rise Worse than Previously Understood

Many global coastlines are lower than previously known, meaning that hundreds of millions more people than expected are vulnerable to sea level rise, according to recent research by non-profit Climate Central. Leveraging a new digital elevation model, Climate Central found that by mid-century "land currently home to 300 million people will fall below the elevation of an average annual coastal flood." While scientists continue to explore the timing and implications around ice sheet collapse, this new research provides improved understanding of global coastal elevations and the potential for dire impacts on economies and communities. 

The space industry is particularly vulnerable to sea level rise. There is little redundancy built in to the industry and the Kennedy Space Center and Cape Canaveral Air Force Station are both exposed to significant coastal flooding. "Complex 39A is estimated to face a 14% annual risk of flooding next year and it’s projected to flood at least once a year on average during the 2060s unless additional measures are taken to protect it according to Climate Central's analysis. By 2100, parts of the launch site could experience near monthly flooding." NASA is building a 17ft high sand dune to protect the launchpads from the rising ocean, but experts wonder if this is a meaningful solution.

Demystifying Climate Scenario Analysis for Financial Stakeholders

December 4, 2019 – 427 REPORT. Scenario analysis is an essential yet challenging component of understanding and preparing for the impacts of climate change on assets, markets and economies. When focusing on the short term, the warming and related impacts we have already committed to calls for scenarios that are decoupled from economic and policy activities and instead focus on the impacts that are already locked in. This report explores which impacts are already locked in, identifies how Representative Concentration Pathway (RCP) scenarios fit into the conversation, and describes an approach to setting up scenario analysis for near-term physical climate risks.

Download the report.

As the effects of climate change increasingly threaten financial stability, investors and regulators are seeking to understand what impacts lie ahead, and calling for an increase in physical climate risk assessment and disclosure in line with the Task Force on Climate-related Financial Disclosures (TCFD). To assess the scale of financial risk posed by physical climate change it is important to quantify risks under different climate scenarios. How will changes in extreme weather patterns, longer droughts and rising seas differ under various scenarios? Answering these questions through scenario analysis helps uncover the range of risks, allowing investors to identify assets and markets that are more likely to become stranded over time and to begin developing forward-looking resilience strategies. However, science-driven, decision-useful scenario analysis poses many challenges for businesses and financial stakeholders today, due to complex feedback loops, varying timescales, and multiple interacting factors that ultimately determine how global climate change manifests.

 

Figure 2. Distribution of daily extreme temperature changes in 2030-2040, expressed as a percent change, relative to a baseline of 1975-2005 under RCP 8.5. This map shows statistically downscaled global climate models averaged together, for this time frame and scenario. NASA Earth Exchange Global Daily Downscaled Projections statistically downscales climate model outputs to a ~25 kilometer resolution (see full details here) White areas are excluded because they lack potential for significant economic activity.

This new report, Demystifying Climate Scenario Analysis for Financial Stakeholders, explores which physical impacts are already locked in, identifies how Representative Concentration Pathway (RCP) scenarios apply, and describes an approach to setting up scenario analysis for near-term physical climate risks. Scenario analysis is often approached from the perspective of transition risk, where policy developments and greenhouse gas (GHG) emission targets are the key drivers of risk pathways over the near-term, in the next 10 to 30 years. Physical risk, however, requires a different approach.  Impacts over the coming decades are largely locked in, making the emissions scenarios less relevant. Unlike transition risk, GHG emission pathways play a minimal role in the behavior of the near-term climate and GHG emission pathways only begin to meaningfully influence global temperatures near mid-century. The uncertainty in physical climate risks in the near-term is driven by uncertainty in physical processes, rather than in policy decisions.

For organizations looking to construct physical climate risk scenarios for risk management and strategy purposes, it is critical to understand the scientific phenomena driving our plausible climate futures. This report outlines an approach called percentile-based analysis, which allows users to explore the range of potential outcomes based on climate model outputs within a single RCP. This offers a flexible, data-driven approach, suitable for portfolio-level screenings, reporting, and in some cases, direct engagement with asset managers.

Key Takeaways:

  • Quantifying climate risks under different scenarios is a key element in understanding how physical climate risks pose financial risks.
  • Scenario analysis is often approached from the perspective of transition risk, where policy developments and greenhouse gas emission targets are the key drivers of risk pathways in the next 10 to 30 years. However, physical climate impacts over the coming decades are largely locked in, so physical risk requires a different approach.
  • Even if we stopped emitting carbon dioxide tomorrow, many physical climate impacts, such as increasing temperatures, more severe droughts, and rising sea levels, would already be locked in because of the time carbon dioxide stays in the atmosphere and the time it takes the atmosphere to respond.
  • The uncertainty in how physical climate risks may manifest in the next few decades is driven by model uncertainty, which should therefore be the focus of scenario analysis for physical climate risks in the near-term.
  • Percentile-based analysis offers a flexible, data-driven approach, suitable for portfolio-level screenings, reporting, and in some cases, direct engagement with asset managers.

Newsletter: Keeping Up with Regulatory Developments on Climate Risk

Four Twenty Seven's monthly newsletter highlights recent developments on climate risk and resilience. This month we feature factsheets on regulatory action for financial climate risk, news from Four Twenty Seven and an update on the latest extreme heat.

In Focus: Financial Regulators Take on Climate Risk

Factsheets: Financial Climate Risk Regulation - What You Need To Know

Our new series, Financial Climate Risk Regulation, provides a summary of key recent and upcoming regulatory actions related to climate risk. From the European Union's directive on disclosure and the Bank of England's insurance stress tests, to France's surveys of its insurance and banking markets and the consultations of the European Supervisory Authorities around integrating sustainability into oversight requirements, regulators are moving quickly on climate risk with global implications for financial actors.

Staying up-to-date on these developments will provide early indications of regulatory action to come and give insight into potential rippling market impacts. Four Twenty Seven's factsheets on regulatory developments in the European Union, France and the United Kingdom, summarize each nation's stance on the financial risk of climate change, outline key actions and highlight upcoming dates to remember.

NGFS Releases Technical Supplement on Climate Risk Assessments

Last week, the Network for Greening the Financial System published an overview of current approaches to assessing climate change's macroeconomic impacts and summarized key topics for further research. The supplement outlines ways for central banks and supervisors to assess climate-related risks through macroeconomic modeling, scenario analysis, stress testing, risk indicators and financial stability assessments.
"This is a Big Deal" - Media Coverage of Four Twenty Seven's Acquisition by Moody's
“This means the old paradigm of discussing climate change as part of so-called ESG (Environmental, Social and Governance) risks is inappropriate. The risks are increasingly physical and specific – the heat waves, the tsunamis, phenomena like the effect on Germany’s economy of two consecutive years’ low water in the Rhine. Models need to be adapted to them, new hedging opportunities created and ratings adjusted. It’s not a matter of fashion or reputation management but of basics like sales, cash flow and profit. Moody’s acquisition is a sign that the financial industry is beginning to take this on board," Leonid Bershidsky writes in a Bloomberg op-ed.

"Moody’s Corporation has purchased a controlling stake in a firm that measures the physical risks of climate change, the latest indication that global warming can threaten the creditworthiness of governments and companies around the world." The New York Times' Christopher Flavelle writes.

Heat Records Broken...Again

Extremely Hot Days are Expected to Continue

Last week, Belgium, Germany and the Netherlands all experienced their highest temperature ever recorded. Paris also hit a record high of 109°F (43°C), after France had its highest ever temperature 45.9°C (114.6°F) during a June heatwave made at least five times more likely due to climate change. Meanwhile, Anchorage, Alaska's 90°F temperatures surpassed previous records by five degrees. The city had at least 34 consecutive days of above average temperatures, with ice melt negatively impacting fishing and hunting and wildfires threatening human health. The eastern and midwest U.S. endured their first heat wave of the season this month, as thunderstorms and record heat disrupted power and took lives.

“There is likely the DNA of climate change in the record-breaking heat that Europe and other parts of the world are experiencing. And it is unfortunately going to continue to worsen,” Marshall Shepherd, professor of meteorology at University of Georgia told the AP. Earlier this month, the Union of Concerned Scientists released data projecting the number of days that will surpass extreme heat indices by mid-century and late century for every U.S. County. Under a 2.4°C (4.3°F) scenario, Los Angeles County may experience an average of 55 days annually with a heat index above 90°F, Dallas County would average 133 days and Broward County, FL 179 days. 

Extreme Heat Has Extreme Impacts on Economies and Human Health

The total cost of lost output due to extreme temperatures is projected to be $2.4 trillion annually according to the International Labor Organization's recent report. Agriculture and construction are expected to lose 60% and 19% of global working hours by 2030, with southern Asia and western Africa expected to experience the greatest losses.

Increasing average temperatures are already affecting industries around the world, as the alpine tourism sector takes a hard look at its climate risks and opportunitiesFrance declares a water shortage and water restrictions affect agriculture and industry across Europe.

Factsheet — Financial Climate Risk Regulation in France

July 29, 2019 – 427 FACTSHEET. In 2015 France laid the groundwork for legislating climate risk disclosure with Article 173 of its Energy Transition Law, mandating that publicly traded companies and asset managers report on their physical and transition risks from climate change. Building on its track record as an early mover, France’s financial regulators are now actively involved in national and international endeavors to frame climate risk as a financial risk and determine the most effective response.  Staying up-to-date on these developments will provide early indications of regulatory action to come. This factsheet on regulatory developments in France provides background on France’s sustainable finance agenda, outlines key actions and highlights upcoming dates to remember.

France’s Art. 173 helped build support for the Taskforce on Climate-related Financial Disclosures recommendations, prompted firms to begin disclosing climate-related risks early and set an example for other nations considering regulation on climate risk disclosure. Since this landmark legislation, French financial regulators have become engaged on addressing financial risks from climate change and the Banque de France was a co-founder and provides the Secretariat for the Network of Central Banks and Supervisors for Greening the Financial System (NGFS), which is focused on propelling the transition to a low-carbon and sustainable economy. By providing the Secretariat for the NGSF, the Banque de France identifies itself as a key player in international efforts to address climate risk. This factsheet, Financial Climate Risk Regulation in France, summarizes France’s stance on the financial risk of climate change, notes key regulatory players and highlights recent and upcoming regulatory action applicable to financial markets.

Key Takeaways

  • Banque de France was the first central bank to release an assessment of its climate risks in line with the TCFD and Art. 173, aiming to set an example of best practice for the French financial sector.
  • ACPR’s fall 2018 survey of the French insurance sector found that disclosures in Art. 173 reports varied between firms and lacked reporting on long-term climate strategies and yearly progress. ACPR made suggestions for insurers to improve their climate risk management based on this review.
  • In summer 2018, ACPR surveyed its banking sector on banks’ climate risk management, identifying “advanced institutions,” larger banks with ample resources that have integrated climate into risk management, and “wait-and-see” institutions, which are largely domestic, retail-oriented banks still focused on a corporate responsibility approach to climate change.
  • France’s stock market regulator, AMF, released a report asserting that climate change has been identified as a financial risk, it is still not sufficiently assessed by the market, and the regulator’s role is to inform and raise awareness on the topic.

Newsletter: Bank of England Publishes First Stress Test for Climate Risks

Four Twenty Seven's monthly newsletter highlights recent developments on climate risk and resilience. This month we feature developments in scenario analysis for physical risks, highlight the European Union's guidance on climate risk disclosure and share the latest on financial climate risk and the need for resilience.

In Focus: Scenario Analysis for Physical Risk

Bank of England Publishes First Climate Risk Stress Test

Yesterday the Bank of England released specifications for integrating climate risk scenarios into its insurance industry's biennial stress tests. This "exploratory" exercise is an enormous step towards catalyzing a growing understanding of possible impacts of transition and physical climate risks on financial assets.

The guidance lays out potential impacts by providing sector-specific percentages of potential loss under three scenarios by sector and by region. These quantitative financial impact assumptions are not a projection but a starting point for the insurance industry to explore potential impacts of climate change on their portfolios.

The Bank of England leveraged Four Twenty Seven's analytics on climate risk exposure in equity and real estate markets to inform its assumptions about which sectors will experience the largest impacts. We explain how data on risk exposure in equities can be leveraged for this type of analysis in our new blog series on scenario analysis.

The Bank of England also recently released a practitioner's guide for assessing the financial impacts of physical climate change, to help the insurance sector address climate risks.

Blog Series: Scenario Analysis for Physical Climate Risk

Our new blog series provides our reflections on how corporations and financial institutions can integrate physical climate risk into scenario analysis. Scenario analysis for physical risk is fundamentally different from transition risk. Corporations and investors increasingly recognize the need to integrate physical risk into scenario analysis but are looking for guidance and best practices on how to proceed.

Our first blog focuses on the foundations, demonstrating how characteristics of climate science affect how climate data can be used to inform scenario analysis. We argue that because physical risks over the next 10-20 years are largely independent from policy decisions and emission pathways, investors would be better served by scenario analysis that focuses on the inherent uncertainty of projected impacts, independent from assumptions on GHG emission scenarios. 

The next blog focuses on Equity Markets, with concrete examples of how available data can inform financial stakeholders ready to start putting scenario analysis into action. We look at data on climate risk exposure by sector to explore how climate risk analytics can inform early developments of stress test assumptions, as done by the Bank of England.

EU Technical Expert Group
Releases Guidance
Yesterday the European Commission released its final guidance on integrating climate change into corporate disclosuresThis guidance applies to 6,000 companies, banks and insurers in Europe and maps to the TCFD recommendations. The guidance includes key recommendations from Advancing TCFD Guidance for Physical Risks and Opportunities, published by the European Bank for Reconstruction and Development (EBRD) and GCECA last year, for which Four Twenty Seven was a lead author. 
The EU also released the Technical Expert Group (TEG) report on a taxonomy for activities that contribute to climate adaptation and mitigation. The taxonomy aims to help investors and policymakers understand which economic activities contribute to the transition to a low-carbon economy, through both mitigation and resilience. It outlines qualitative screening criteria to identify adaptation of economic activities and adaptation by economic activities, providing activity-specific examples for a range of sectors. The proposed taxonomy is still under legislative review.
Second TCFD Status Report
While more firms are releasing TCFD disclosures, investors call for an increase in informative disclosure of the financial impact of climate risks. The Task Force on Climate-related Financial Disclosures (TCFD) released its second progress report earlier this month, emphasizing that the quality of risk disclosures must continue to improve as firms build their understanding and capacity to address climate risks. 91% of surveyed firms said they plan to at least partially implement the TCFD recommendations, but only 67% plan to complete implementation within the next three years. This progress must be accompanied by continued knowledge sharing and research on financial risk pathways for climate impacts, meaningful exposure data and best practices for reporting.

Even as TCFD reporting increases, quantitative assessment of physical risk exposure lags behind. Explore physical climate risk reporting by French firms in our analysis of physical risk in Article 173 reports and stay tuned for Four Twenty Seven's forthcoming analysis on physical risk disclosure in TCFD reports.
Investors Factor Climate Risk into Decisions
The past month has seen a flurry of news around the business risks of climate change and the financial sector response. CDP's annual climate change report estimates that 215 companies could incur around $1 trillion in climate-related costs if they don't prepare for these impacts. Companies expect these costs to begin accumulating in around five years. While some are not yet acting, others are, such as Japanese Hitachi Ltd preparing for increased rainfall in Southeast Asia and Brazilian Bank, Banco Santander, considering how increased water stress may damage borrowers' ability to repay loans. 

Alison Martin of Zurich Insurance Group told a meeting of CFOs that physical risks such as drought, extreme heat and flooding will be "incredibly meaningful." She emphasizes that the first step in integrating climate change into planning is for a company to understand its risk exposure. Meanwhile investors say they are increasingly factoring physical climate risk into their decision-making to minimize their risk and increase returns. Four Twenty Seven's on-demand scoring of real assets and analysis of asset-level risk in equity portfolios enables both corporations and investors to understand their exposure and strategically address physical climate risks.
Devastating Impacts Call for Preparation

Catastrophic Midwest Flooding Has Rippling Impacts

At the end of May only 58% and 29% of the U.S. corn and soy crops had been planted respectively. After persistent flooding beginning in Mid-March, inundated fields delayed planting. This means that some farmers will miss the planting window, which closes in June due to the heat and dryness of later summer months.
Those crops that do get planted will have to overcome soggy soil conditions and will remain at the peril of the summer's weather. It's already clear that this will be a below average crop yield, which translates into  more expensive corn in cattle feed and higher prices in grocery stores.

The Climate Connection

While the Mississippi River continues to swell, extreme precipitation has recently hit Houston and the Southeast with damaging floods. The past 12 months have been the wettest on record for the U.S. The national average of 37.7 inches since last June is 7.7 inches above average. 
A weak El Niño likely contributed to increased rainfall, but climate change also plays a role as warmer air holds more water. This month also saw record high temperatures in the western U.S., caused by a bulging jet stream making warm air flow south to north. While this does happen naturally, it may be happening more often due to warming ocean waters. This jet stream activity also contributes to other extreme events like the Midwest flooding.

The Need to Rethink Preparedness

From floods and heat waves to fires and hurricanes, federal recovery efforts for extreme events have cost almost half a trillion dollars since 2005. As disasters become more common and costs increase, there is an urgent need to invest in resilience proactively rather than spending billions on recovery. Last fall's Disaster Recovery Reform Act made an
important step by allowing FEMA to use a small portion of its disaster relief funding for risk mitigation ahead of disasters. However, this is the start of what must be a systemic shift in addressing extreme events. “If we don’t want to spend hundreds of billions of dollars on recovering for disaster, we need to spend tens of billions [on resilience],” Four Twenty Seven Strategic Advisor, Josh Sawislak, told Bloomberg.

"There is a silver lining to our climate challenges — economic growth. Americans are very good at innovating and building and we can leverage our need to be more resilient by growing the economy with good resilient and sustainable jobs," Sawislak wrote.

Scenario Analysis for Physical Climate Risk: Equity Markets

In this second installment of our blog series of scenario analysis, we focus on how investors can start exploring impacts on portfolios of listed equities/fixed income with existing climate risk analytics. The series provides our current reflections on how corporations and financial institutions can integrate physical climate risk into scenario analysis. The first installment, on foundations, focuses on important characteristics of climate science that affect how climate data can be used to inform scenario analysis for economic and financial risk. A forthcoming post will discuss scenario analysis at the asset level for real asset investments and corporate facilities.

Scenario Analysis Serves Different Purposes

Scenario analysis serves different purposes for real asset investors and for equity or fixed income investors. When looking at a single real asset, scenario analysis can be used to inform very concrete decisions regarding the asset, working directly with the asset operator: whether and what flood protections to put in place, insurance requirements, anticipated impacts on operational costs from water and energy consumption, etc.

In contrast, for an equity or fixed income portfolio, investors’ influence on the resilience of the underlying asset (e.g. a corporation or a sovereign entity) is much more limited. In a previous publication we discussed the importance of shareholder engagement with corporations as a key channel for investors to help raise awareness of rising risks from climate change, and encourage companies to invest in responsible corporate adaptation measures. Investors, however, would be hard pressed to run scenario analysis on individual portfolio companies themselves, and disclosures from corporations on scenario analysis remain weak and fragmented.

Meanwhile, prudential authorities in Europe have been signalling expectations that insurers and banks perform scenario analysis on their portfolio to examine potential impacts of climate change, to understand how different climate-driven outcomes might prevent the insurers and lenders from meeting their financial obligations. Most recently, in April, the Bank of England Prudential Regulatory Authority (PRA) released a proposed set of specifications for scenario analysis that includes some simplified assumptions on climate impacts on financial portfolios.

In this piece we examine how available climate risk analytics can be leveraged to inform early attempts at developing stress test assumptions and simulate potential outcomes on investment portfolios aligned with the relative exposure of corporations by sectors and by regions.

Climate Risk Analytics for Equities/Fixed Income

We leverage our data on corporate physical risk exposure to determine what assumptions can be made in this type of early stress test. In this piece, we analyze the climate risk scores for 1730 of the largest companies in MSCI All Country World Index (ACWI). This physical risk assessment is based on the exposure of the underlying database of about a million facilities globally.

We score each company on three components of physical climate risk: Operations Risk, Supply Chain Risk and Market Risk.

427 Methodology Chart
Figure 1. 427 indicators for physical climate risk exposure in corporations (equities/fixed income)
  • A company’s Operations Risk is based on its facility-level exposure to hurricanes & typhoons, sea level rise, floods, extreme heat and water stress. The analysis also considers the sensitivity of different types of facilities. For example, manufacturing plants with their high energy demands are more sensitive to extreme heat than offices.
  • Supply Chain Risk is based on the risk in countries that export commodities that the company depends on and a company’s reliance on climate-sensitive resources such as water, land and energy, based on its industry.
  • Market Risk is based on where a company’s sales are generated and how its industry has historically been impacted by weather variability.

Scores are normalized, with 0 being the least exposed and 100 being the most exposed. (For more details, please refer to our previous report Physical Climate Risk in Equity Portfolios as well as our Solutions page)

In line with considerations of relevant time horizons and of impacts being locked in over the climatic short term (detailed in Part 1), our standard equity risk score data considers projected climate impacts in the 2030-2040 time period under a single RCP scenario, RCP 8.5 (the worst case scenario, also known as business as usual), but leverages several climate models.

From Climate Hazard Exposure to Financial Impacts

Studies of how physical climate hazards translate into financial impacts at the company level are scarce. While a growing body of research explores the complex relationships between climate hazards and economic impacts, which vary by sector and by region, academic research on the relationship between climate events and corporate/stock performance, at scale, is still limited. Our approach focuses on leveraging what can be estimated in a robust, data-driven way: relative exposure of companies to climate hazards.

Our analysis of global corporations shows the relative exposure of industries to climate related risks across all three dimensions: operations risk, market risk and supply chain risk (Table 1). This table shows the sectors with the highest exposure, including manufacturing, infrastructure (utility, energy, transportation), and industries with high dependency on natural resources (food, apparel).

Table 1. Industries most exposed to physical climate risks . Source: Four Twenty Seven.

Services, not shown in the table, are not only less exposed, they’re also far less sensitive to changes in climatic conditions, with the exception of the financial sector, which holds the risk of all the other sectors in its investment, lending or insurance portfolios. Note that real estate is not included in this analysis, but data on regional exposure in that sector can be found in our white paper on climate risk in real estate.

These differentiated impacts by sectors can lay the foundations for a stress test, as industry risk levels can be used to set initial assumptions on sector-wide impacts. Following the example set out by the Bank of England’s PRA, for example, investors could assume that sectors with high exposure might see a 10% or 20% drop in value, whereas sectors with medium exposure would see half of that impact. These assumptions are not intended to substitute for financial impact modeling, but provide a shortcut to test how a portfolio might perform under climate-driven duress.

Drivers of Exposure to Physical Climate Risk

While some sectors overlap with those examined in scenario analysis exercises for transition risk, such as utilities and energy, other sectors with high exposure are not typically included in scenario analysis, like tech manufacturing or pharmaceuticals. Understanding the nuances of the risk pathways in each sector and their relative exposure to different hazards is critical to refining assumptions and developing models that can quantify value-at-risk by sector with some accuracy.

Manufacturing companies in the tech sector rely on complex value chains that can be interrupted by extreme weather events, particularly in Asia, which is a region highly exposed to typhoons and extreme precipitation. They also often produce expensive and water sensitive products using costly machinery and can incur costs and damages from extreme events on site.  Pharmaceuticals are particularly exposed because of the prevalence of their manufacturing in water-stressed regions (India, California) and regions highly exposed to hurricanes & typhoons. For example, damaged manufacturing sites in Puerto Rico had rippling impacts on pharmaceutical operations globally during Hurricane Maria in 2017. Pharmaceuticals is also one of the groups with the most weight in the MSCI ACWI, making this exposure particularly significant (Fig 2).

Figure 2. The average company risk score by GICS Industry Group, with Operations Risk on the y-axis and Market & Supply Chain Risk on the x-axis. Red represents those industries with the highest exposure, green represents those with the lowest exposure and the size of the bubble signifies an industry’s weight in the MSCI ACWI.  Source: Four Twenty Seven.

In the utility sector, the nature of the exposure is very different from that observed in transition risk analysis: carbon neutral power generation can be as exposed as thermal generation – for example due to water stress or floods for hydro facilities. In addition, utilities rely on expensive equipment, such as cables, poles, fuel storage and pipes that are often exposed to severe weather and sensitive to extreme conditions. Their operations are also resource-intensive, relying heavily on energy and water for cooling. They can experience operations disruptions during peak energy demands or due to equipment damage during storms.

The exposure of the automobiles & components sector has been illustrated by recent flooding in Japan. Automobile companies rely on manufacturing processes and machinery that can be interrupted due to flooding or hurricane damage, but their reliance on employee labor also makes these companies vulnerable to the wider regional impacts of extreme events. For example, during Japan’s extreme flooding in July 2018, Mazda was forced to halt operations at some of its facilities that were not physically damaged themselves, because its employees could not travel safely to work.

Conclusion

Climate change calls for a better understanding of impacts of physical hazards on financial markets, which remains a topic largely unexplored. Yet as regulators push insurers and banks towards the integration of climate scenarios into stress testing, robust, data-driven views on the relative exposure of sectors or regions provide a helpful foundation from which to explore the potential impacts on equity and fixed income portfolios.

Over time, better data will become available as academic and industry providers develop models that capture the nuances of climate impacts on different industries and geographies, but also as companies make a concerted effort to disclose better data on their past and anticipated financial exposure to extreme weather and climate-related events.

Scenario Analysis for Physical Climate Risk: Foundations

The TCFD Status Report published early June 2019 reiterates the need for corporations and financial institutions to perform scenario analysis in a context of uncertainty over climate risk. It notes that while about 56% of companies use scenario analysis, only 33% perform scenario analysis for physical risk. Even fewer firms (43% of those using scenario analysis) disclose their assumptions and findings. The report contains useful case studies, but most focus on transition risk.

Yet a growing number of corporations and financial institutions recognize the need to integrate physical risk into scenario analysis and to develop resilience strategies that address imminent challenges from climate impacts. For example, the most recent IPCC report illustrating the impact of 1.5˚C increase in global temperatures on mean temperatures, extreme temperatures, extreme precipitation and sea levels shows that there will be significant implications for economies even with a 1.5˚C increase in global temperatures. This is still a best case scenario compared to impacts of 2˚C or 2.5˚C warming.

Scenario analysis for physical risk is fundamentally different from transition risk in its challenges and assumptions. This blog series provides our current reflections on how corporations and financial institutions can integrate physical climate risk into scenario analysis. This first blog presents the Foundations, focusing on important characteristics of climate science that affect how climate data can be used to inform scenario analysis for economic and financial risk. The next blog focuses on Equity Markets, with concrete examples of how available data can inform financial stakeholders ready to start putting scenario analysis into action. A forthcoming post will discuss scenario analysis at the asset level for real asset investments and corporate facilities.

Part 1: Foundations

The physical impacts of climate change encompass a range of direct and indirect hazards caused or exacerbated by the concentration of greenhouse gases in the atmosphere. Previous publications such as Advancing TFCD Guidance for Physical Risks and Opportunities, for which Four Twenty Seven was a lead author, provide background on these hazards as they pertain to corporate value chains and economic activities. Further information is also available in Cicero’s excellent report, Shades of Climate Risk. Categorizing climate risk for investors.

The Science: Uncertainties and Relevant Time Frames

Rapid developments in atmospheric and climate science over the past 30 years enable us to understand how these physical hazards will evolve over time due to climate change. Sophisticated global climate models project expected changes in key physical phenomena affected by greenhouse gas (GHG) concentration: heat, humidity, precipitation, ocean temperature, ocean acidification, etc. Like any other models, climate models have limitations in their accuracy and ability to correctly simulate complex and interrelated phenomena. However, it is worth noting that since 1973 models have been consistently successful in projecting within the range of warming that we have experienced in the past twenty years. More details on climate data and uncertainties from global climate models can be found in our report, Using Climate Data.

The Bad News: Impacts Are Locked In

Global climate models project different possible outcomes using scenarios called Representative Concentration Pathways (RCPs). RCP scenarios capture differing GHG emissions trajectories based on a representation of plausible global policy outcomes, without specifying the details of the underlying policies that could generate this outcome. These scenarios show that GHG emissions generated over the coming decades will influence the severity of impacts in the long-term, but also that we are already committed to some impacts through 2100 and beyond.

This is particularly noticeable over the “short term.”  When looking at the next 10 to 20 years, projections for temperature and other physical hazards do not present significant differences under different emissions scenarios (Fig 1). This is due to the massive inertia of the Earth’s systems, and the life expectancy of the stock of greenhouse gases already in the atmosphere. To put it simply, significantly reducing GHG emissions is akin to applying the brakes on a rapidly moving truck. It won’t stop instantaneously. Even if we were to stop emitting GHG altogether, climate change would persist. In the words of the Intergovernmental Panel On Climate Change (IPCC), climate change “represents a substantial multi-century commitment created by the past, present, and future emissions of CO2.”

Figure 1. Temperature increases under different GHG emissions scenarios in the near term. Source: IPCC, as published by Climate Lab Book.

This is by no mean an invitation to give up on reducing GHG emissions. Quite the opposite. Emission reductions are critical to curbing long term impacts and avoiding irreversible effects to our environment (Fig. 2). But for organizations looking at climate data and scenario analysis for risk management and strategy, with a focus on the coming decade(s), this is a critical fact to understand.

Projections are shown for each RCP for the multi-model mean (solid lines) and the 5 to 95% range (±1.64 standard deviation) across the distribution of individual models (shading). Discontinuities at 2100 are due to different numbers of models performing the extension runs beyond the 21st century and have no physical meaning. Only one ensemble member is used from each model and numbers in the figure indicate the number of different models contributing to the different time periods. No ranges are given for the RCP6.0 projections beyond 2100 as only two models are available.Source IPCC AR5: Collins, M., R. Knutti, J. Arblaster, J.-L. Dufresne, T. Fichefet, P. Friedlingstein, X.

Temperature increases under different GHG emissions scenarios through 2300 from IPCC AR 5: Figure 12.5 | Time series of global annual mean surface air temperature anomalies (relative to 1986–2005) from CMIP5 concentration-driven experiments. Projections are shown for each RCP for the multi-model mean (solid lines) and the 5 to 95% range (±1.64 standard deviation) across the distribution of individual models (shading). Discontinuities at 2100 are due to different numbers of models performing the extension runs beyond the 21st century and have no physical meaning. Only one ensemble member is used from each model and numbers in the figure indicate the number of different models contributing to the different time periods. No ranges are given for the RCP6.0 projections beyond 2100 as only two models are available.
Aside from RCP-driven scenarios, there is, of course, a broad range of possible increases in temperature (and other climate hazards) even when looking at the 2030-2040 time frame. These plausible differences are not so much policy-driven as science-driven, demonstrating the different possible responses from the Earth’s systems to the existing stock of GHG.

These differences have significant implications for businesses and investors. For example, a model of sea level rise developed in 2018 incorporates accelerated rates of melting and recent advancements in modelling ice-cliff dynamics to capture extreme risk of coastal flooding. The model shows the Atlantic rising by 1.2m (3.9ft) by 2060 on the Florida coastline, which would equate to widespread flooding of coastal properties with potential domino effects on real estate prices across the state (Fig 3). The ‘intermediate’ scenario, however, most often used for planning, predicts only a 55cm (1.8ft) rise in water levels. While reducing GHG emissions does reduce the risk of more extreme sea level rise millennia into the future, year after year, scientists find that the Antarctic is warming faster than anybody predicted, and there is increasing concern that the process of ice sheet melt may be too far advanced to be stopped.

Figure 3. Building-level perspective of inundation in downtown Miami under 1m (3.3ft). Red buildings are those most likely to be impacted and blue areas are inundated. Source: NOAA Office for Coastal Management.

Thus, performing scenario analysis where the key variable is GHG emission reduction targets may not be an accurate representation of the range of possible outcomes for the near future. Rather, looking at high and low warming projections across a large set of models to understand the range of potential outcomes (independent of the underlying RCP scenario) is a better way to understand potential risk. In other words, physical risks over the next 10-20 years are largely independent from policy decisions and emission pathways, and a rapid, orderly, effective transition to a low-carbon economy could still come with massive physical impacts as these processes are already under way, fueled by the past 150 years of GHG emissions.

The Worse News: Tipping Points

Another challenge is that climate scientists are not currently able to model certain possible impacts from climate change, commonly known as “tipping points.” Tipping points is a catch-all term for a wide range of phenomena that may accelerate feedbacks due to climate change, though the timing or probability of their manifestation is currently not well understood. The phenomena are known as tipping points because past a certain threshold, they may not be reversible, even with a dramatic reduction in GHG emissions. Tipping points of most concern to the scientific community are presented in this report from the Environmental Defense Fund.

Some tipping points catalyze “feedback loops” which can worsen and dramatically accelerate climate change beyond human control. Such is the case, for example, with melting ice sheets, which would not only lead to catastrophic sea level rise, but would also further heat up the planet as the poles’ albedo (reflectivity) is reduced after the ice disappears. Thawing permafrost could lead to massive amounts of methane, a particularly powerful GHG, to be released from the frozen tundra into the atmosphere (in addition to many direct impacts for local communities, infrastructure  and ecosystems in the region).

Tipping points further reinforce uncertainty about severity and timing of these extreme impacts and the limitations of using RCP scenarios to understand the range of outcomes for physical risk.

Another source of uncertainty for physical climate impacts are knock-on effects, or ‘indirect hazards,’ from the primary expression of global warming (rising temperature and humidity), ranging from biodiversity losses and ecosystem collapses, human health impacts, impacts on crop yields, pests and soil, impacts on human society, increased violence, and rates of war and migration, etc. (Fig 4)

Figure 4. The likely risks to human and natural systems under several global warming scenarios, with dark purple representing high risks of severe impacts with limited reversibility and white indicating no attributable impacts. Source: IPCC, 2018

These indirect or second-order hazards are as relevant as first-order impacts to understand the implications of physical climate change on economic outcomes, but they’re not captured by RCP scenarios and many require stand-alone models that cannot easily be integrated into one clean set of scenarios.

Conclusion

Scenario analysis is often approached from the perspective of transition risk, where policy developments and GHG emission targets are the key drivers of risk pathways over the next 10 to 30 years. Physical risk, however, requires a different approach. Impacts over the coming decades are largely locked-in and are only marginally influenced by GHG emission pathways. In contrast, uncertainty looms large regarding how severe these physical hazards will be, and exploring a range of possible outcomes for physical risk, including looking at tail-risks, provides important insights for risk management and financial analysis.  In summary, the current state of scientific knowledge and the nature of the Earth’s atmospheric systems call for the developments of scenarios that are decoupled from transition/policy scenarios and instead focused on key scientific drivers of uncertainty and risks that may be experienced regardless of policy decisions over the short to medium term (2020-2040).

While efforts to develop easy-to-use tools for physical risk analysis are nascent, organizations can still extract important insights from climate data and leverage estimates of risk exposure across portfolios. Our next blog in this series provides examples of how financial institutions can leverage data on physical risk exposure in equities to inform some early scenario analysis in equity markets.
