Climate Change: An Economic Risk for Canadian Municipalities

Introduction

The planet has just finished its hottest decade on record, leaving municipalities and businesses wondering how best to prepare for the future. As climate change increases the frequency and intensity of both extreme weather events like storms and heat waves, and chronic stresses like drought and sea level rise, the past is no longer an accurate prediction of the present.

While Canada’s latitude and geography makes it less exposed to widespread threats such as heat stress and hurricanes, its exposure to water stress and floods, alongside its economic dependency on water-heavy industries such as extraction, refining and manufacturing, does present significant risks. From striving to keep their residents safe, to supporting regional businesses, maintaining economic prosperity and minimizing costs, there are many reasons that municipal leaders need to understand and prepare for climate impacts.

This article outlines how climate risk presents economic risks to municipalities, as well as the investors with assets in the jurisdictions, and describes case studies of economic risk exposure in Canadian cities.

Why it Matters

Climate change poses economic risks to municipalities by impacting key companies, reducing the tax base, and affecting the budget. When companies that make up significant portions of a municipality’s economy — by way of revenue, taxes and employment —are disrupted by climate change, this has negative implications for the municipality. If these events happen repeatedly, it’s likely that jobs and, potentially the population, will decline, reducing the municipality’s revenue from taxes.

For example, low snowfall and a record dry summer in 2013 and 2014 led to reduced hydropower generation in Canada’s Northwest Territories, with implications for businesses with high power demands such as manufacturing and mining. These industries make up significant portions of Canada’s economy and an increase in water stress is likely to have enduring impacts.

Extreme weather events also lead to increased costs for municipalities in the form of emergency relief and rebuilding. For example, in Spring 2019 thousands were evacuated during flooding in Eastern Canada due to high snow melt combined with heavy rainfall, with costs expected to be in the hundreds of millions. At the time there was relatively low overland flood insurance coverage, so there were significant uninsured costs. These events also disrupt transit infrastructure, with implications for commutes and regional business operations.

Increasing expenditures on emergency relief can have implications for municipalities’ other budget items, debt reserves and ultimately their ability to repay loans. Likewise, persistent regional disruptions can have material impacts on businesses with key assets in the area.

Addressing Shared Climate Risks to Build Community-Corporate Resilience

Introduction: Companies Begin Adapting to Climate Change

Increasingly severe and frequent extreme weather events and chronic stresses are threatening urban communities and economic stability globally. In September 2019, during Typhoon Faxai almost a million people lost power throughout Tokyo and commuter trains were canceled. Evacuations were ordered, disrupting both residential life and business operations. Sony stopped operations at a PlayStation 4 console manufacturing site due to power outages, a Nissan production facility was partly flooded, and 10 shipping containers tipped over at Tokyo Port. In the United States, Hurricane Dorian led to the closure of ports spanning from Miami to Georgetown, with implications for local and global trade and the businesses downstream in the supply chain.

Businesses are increasingly aware that climate change hazards pose financial risks through operational disruptions and repair costs. Some corporations are beginning to implement resilience measures, investing in forward-looking climate risk assessments, considering flood resilience measures for their facilities, and improving their water efficiency. However, asset-level preparedness is only the beginning of essential climate resilience measures that businesses must take. Economic resilience is integrally connected to community resilience because corporations rely on functional transportation, power, and water infrastructure for their operations and depend on the city residents that make up their employee and client bases.

Economic Resilience & Community Resilience: Two Pieces of the Same Puzzle

Economic resilience is critical to community resilience, while business continuity is also dependent on resilient communities and infrastructure. Local businesses underpin local economies, which are key to maintaining stability within a city. As credit rating agencies increasingly integrate physical climate risks into their municipal bond ratings, cities’ preparedness for climate impacts will shape their access to capital. Economic stability is a key element in credit rating agencies’ methodologies for determining municipal credit ratings. Thus, the resilience of local business and economic activities to climate impacts will be a key feature of assessments of city climate resilience.

Likewise, local businesses contribute directly to community resilience. Job opportunities attract new residents to cities and a growing population means a growing tax base, with more financial resources to invest in adaptation. When local businesses recover quickly after extreme events, residents retain their jobs and are more likely to stay in the area, both sustaining the tax base and maintaining social capital—an important element of urban resilience. When businesses are resilient to extreme events they can also offer emergency support, including turning their facilities into shelters, offering food, and donating rescue and first aid equipment, as seen after Hurricane Harvey hit Houston in 2017.

However, it is not a one-way relationship. If a catastrophic hurricane or wildfire destroys homes, displaces residents, and disrupts transportation infrastructure in a city, even climate-proofed corporate facilities will not be able to operate effectively. If employees cannot get to work safely or if they are displaced from the area, business operations may be disrupted. Likewise, if goods cannot be transported to and from a manufacturing facility or storage center, disruptions can ripple through supply chains with wide economic impacts. During Japan’s deadly rainfall in July 2018, Mazda Motor Corporation’s headquarters incurred no major damage. However, operations were halted for days because over 100 employees had flooded homes and many faced challenges traveling to work.

Innovation: Partnering Across Sectors for Shared Resilience

Since the resilience of businesses and cities is inextricably connected, the most effective resilience-building will involve collaborating towards shared resilience. Private and public sector stakeholders often use different terms, have different operating and planning processes, and are unaccustomed to collaborating with counterparts from the public or private sector. The development of a model for private-public partnerships that leverages respective strengths and advances shared climate resilience priorities, is a needed innovation.

Businesses and governments must work to establish trust and create a shared language around climate risks, establishing a foundation for successful collaboration on proactive adaptation and resilience planning as well as disaster response. Each can engage by identifying and contributing their strengths to shared efforts. Businesses can provide resources for the adaptation planning process and implementation, including technical expertise, staff time, and financial resources. For example, Facebook contributed over $200,000 to the development of the San Francisquito Creek Joint Powers Authority’s strategy for sea level rise resilience along the San Francisco Bay, which had implications for its Menlo Park campus. These local vulnerability assessments or adaptation plans can inform businesses’ own resilience-building efforts, while climate risk assessments completed for corporate risk management initiatives can also inform regional resilience planning. Information-sharing goes both ways.

Corporations rely on community adaptation to build resilient regional infrastructure and minimize the impacts of extreme events on their assets. Private-public partnerships can be an important mechanism for building support for these initiatives. For example, the Bay Area business community was influential in passing Measure AA, the regional parcel tax to restore the San Francisco Bay and improve resilience to flooding.

Private-public partnerships can also identify opportunities to increase regional preparedness for extreme events. For example, Airbnb works with San Francisco’s Hub for Emergency Preparedness and Portland, Oregon, to enable hosts to offer their homes for free and for other residents to open their homes to disaster victims in areas affected by an extreme event. This system allowed Airbnb to provide lodging to residents in the wake of Hurricanes Harvey, Maria and Irma in 2017, potentially reducing emigration and increasing the possibility of residents continuing to go to work.

As companies begin to incorporate forward-looking climate risk assessment into their processes, they are increasingly well positioned to engage with the surrounding community to support informed resilience building. Likewise, local governments can bring their understanding of climate change impacts on city infrastructure and operations to inform collaborations with the businesses in their community. Effective partnership, leveraging shared objectives and values, as well as unique capabilities, is called for now to improve economic and urban resilience in the face of changing climate conditions.

AIA Video: Stripping Down Climate Risk

Why do climate risks matter for real assets and how can we invest in a more resilient future? There is a growing need to ensure that infrastructure assets and real estate are built to withstand the increasingly severe weather events we experience in a changing climate. Four Twenty Seven Strategic Advisor, Josh Sawislak, discusses how different types of uncertainty will influence physical climate impacts and transition risk outcomes, and how asset design can consider these impacts. Innovating in climate resilience is essential to reduce risk management costs, but it also provides economic opportunities around job creation and product development.

Four Twenty Seven offers real asset screenings and data on climate risk in real estate to inform climate risk mitigation and investments in resilience. Read our paper on Climate Risk, Real Estate, and the Bottom Line or our blogs on scenario analysis for physical climate risk to learn more about these topics.

Disasters are Getting Worse and We Need a New Plan

I couldn’t seem to turn on the TV this week without being inundated with coverage of the ongoing floods and tornadoes in the Midwest. The dearth of other content is not just due the doldrums of the sports and political seasons — things are genuinely getting worse on the disaster front. Much worse.

The horrible scenes of twister damaged homes across the Midwest and continuing flooding along the entire Mississippi River merely displaced the stories on recovery efforts from the Hurricanes Maria, Irma, Harvey, Michael as well as the Camp Fire and other drought inflamed disasters in California and the Western U.S.

The Fourth National Climate Assessment predicts more frequent and severe storms, longer and more severe droughts, and the continued and likely accelerating rise of sea levels. All of this will only add to the challenges faced by states, counties and municipalities that are on the front lines of these disasters and to the taxpayers who foot the bill for the hundreds of billions in recovery and rebuilding costs.

The Government Accountability Office found that the increasing frequency and scale of disasters as well as the federal government’s role in funding recovery and flood and crop insurance, make climate disaster a high risk for federal fiscal exposure. GAO reported that the federal recovery efforts alone have cost nearly half a trillion dollars since 2005. To put that spending in context, it represents approximately $4,000 out of the pockets of every American family. Congress will either have to put our nation further into debt or shift the burden to our taxpayers. Addressing climate change is not only an environmental imperative, it’s critical to our nation’s economic security.

It is clear that we have learned a lot about how to respond to, and recover from, major disasters. In the past 40 years. federal agencies, state and local governments, and the extensive network of volunteer organizations such as the American Red Cross, Habitat for Humanity and the Cajun Navy deserve much credit for their growing ability to save lives and help rebuild communities.

It is also clear that just getting better at response and recovery will keep us on the defensive, always playing catch-up. More importantly, the focus and investment post-disaster does little to keep us safe in the first place. We have to retire the old approach that we can just come in after the storm or fire and rebuild — even if we rebuild stronger. Ask anyone who lost their home, business, community or especially a loved one to one of these disasters. They will tell you that as appreciative as they are for the world-class support from governments and volunteers, it’s small comfort for the trauma and years of personal recovery they face. We need to get ahead of the curve by investing in resilient communities and infrastructure so fewer families have to live in devastation.

Congress is beginning to address this. While some members seemed locked in a partisan fight that is keeping funding from storm and fire ravaged communities in Texas, Florida, Puerto Rico, and California, Congress did add a program in the 2018 Disaster Recovery Reform Act that shines a ray of hope on efforts to be more proactive in disaster mitigation. The creation of a National Public Infrastructure Pre-Disaster Mitigation fund, which FEMA plans to implement through a new program called Building Resilient Infrastructure and Communities allows FEMA to invest in communities before a disaster strikes. Research by the National Institute of Building Sciences found that just building to the current resilient building codes returns 11 times the cost of the initial investment. FEMA’s new program will allow several hundred million dollars in resilient investments to move forward each year without having to run the congressional appropriations gauntlet, but this is really just a small start.

FEMA’s new pre-disaster fund represents only six cents for every dollar spent on reactive recovery. We need to help communities rebuild, but we also need to be serious about investing to make our communities safe from the coming storms, fires, and other climate threats. While construction to current resilient building codes is the right answer for new construction, it doesn’t address the vast balance of structures built on codes that are old and don’t address the new science and technology of climate resilience. We need to invest in fixing or replacing our failing infrastructure and ensuring that all new construction is resilient to future risks — or we will face this problem all over again.

This doesn’t mean that the federal government alone shoulders the entire responsibility. A successful resilience strategy will only work if we bring both the public and the private sectors into the fight. Resilient building codes are one example, but we also need to value and incentivize resilient investments for everyone.

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. Some of these jobs are found in building, upgrading and maintaining our new and existing infrastructure to make it resilient to the increasing risks from a climate-impacted world.

Not only can we put Americans to work building our resilient future, we can take the lessons we learn in that effort and export it to the rest of the world. This is an approach that works for all Americans and provides a strong economic as well as environmental future for people in all parts of our nation and the world.

This is what we did to become world leaders in democracy, agriculture, manufacturing and technology in the previous centuries, and we can do it with climate in the 21st century. Climate change is real and addressing it is literally an opportunity we can’t afford to ignore.

Four Twenty Seven Wins Climate Change Business Journal Awards

FEBRUARY 19, 2019 – SAN DIEGO, CALIFORNIA – Four Twenty Seven receives Climate Change Business Journal Awards for three climate change risk and resilience projects. 

The Climate Change Business Journal (CCBJ) released its 10th annual CCBJ Business Achievement Awards, recognizing outstanding business performance in the climate change industry. CCBJ assesses markets and business opportunities across the emerging climate change industry and acknowledged Four Twenty Seven’s contributions to this field through our global dataset on climate risk in real estate, the development of the California Heat Assessment Tool and our contribution to the EBRD-GCECA initiative on Advancing TCFD Guidance on Physical Climate Risks and Opportunities.

Four Twenty Seven and GeoPhy earned the Technology Merit: Climate Change Risk Modeling and Assessment award for releasing the first global dataset on climate risk exposure in real estate investment trusts (REITs). REITs represent an increasingly important asset class that provides investors with a vehicle for gaining exposure to real estate portfolios. However, real estate is also increasingly affected by risks from climate change. Four Twenty Seven applied its scoring model of asset-level climate risk exposure to GeoPhy’s database of listed REITs holdings to create the first global, scientific assessment of REITs’ exposure to climate risk.

The California Heat Assessment Tool (CHAT) earned the Project Merit: Climate Change Adaptation and Resilience award for its innovative approach to helping public health officials, health professionals and residents understand what changing heat wave conditions mean for them, through a free online platform. CHAT is part of California’s Fourth Climate Change Assessment, a state-mandated research program to assess climate change impacts in California, and was developed by Four Twenty Seven, Argos Analytics, the Public Health Institute and Habitat 7 with technical support from the California Department of Public Health.

The European Bank for Reconstruction and Development and the Global Centre of Excellence on Climate Adaptation initiative on Advancing the TCFD Recommendations on Physical Climate Risks and Opportunities earned the Advancing Best Practices: Climate Change Adaptation and Resilience award. This project culminated in a conference and report building on Taskforce on Climate-related Financial Disclosure (TCFD) recommendations and providing common foundations for the disclosure of climate-related physical risks and opportunities. It identifies where further research or market action is needed so that detailed, consistent, industry-specific guidelines can be developed on the methodology for quantifying and reporting these risks and opportunities. Four Twenty Seven and Acclimatise provided the technical secretariat that led the working groups and authored the report.

The California Heat Assessment Tool

As California’s climate warms, residents increasingly endure extreme heat events that adversely impact public health. This exacerbates existing risks and will bring new challenges for different regions in the state, threatening the efficacy of traditional intervention strategies. Current thresholds for heat alerts are based on temperatures that exceed historical statistical thresholds, rather than temperatures that cause public health impacts. These ‘health-neutral’ thresholds may underestimate the health risks for the most sensitive populations. The new California Heat Assessment Tool (CHAT) is based on research that establishes local, health-based thresholds for extreme heat that help public officials, health professionals and residents understand what changing conditions mean for them. CHAT is part of California’s Fourth Climate Change Assessment, a state-mandated research program to assess climate change impacts in California, and was developed by Four Twenty Seven, Argos Analytics, the Public Health Institute and Habitat 7 with technical support from the California Department of Public Health.

Explore CHAT at cal-heat.org.  This online tool advances the understanding of what types of heat waves pose public health risks and examines how the frequency and severity of local heat waves are expected to change over time due to climate change.

Read a brief report, The California Heat Assessment Tool: Planning for the Health Impacts of Extreme Heat, that shares key findings from the research and summarizes the data analysis visualized in the tool.

Key Takeaways

  • Current climate change projections show that a typical California summer in 2100 may be 4-5° F warmer than today. Heat waves are also lasting longer, occurring later into the summer season and in areas less accustomed to heat waves.
  • Elderly or very young people, outdoor workers and individuals with preexisting health conditions or limited resources are most sensitive to the impacts of extreme heat and may be disproportionately affected. Some of these sensitive, or frontline, populations may experience adverse health impacts at temperatures 6-8° F lower than the general population.
  • Current thresholds for heat alerts are based on temperatures that exceed certain statistical thresholds, rather than temperatures that cause public health impacts. These health-neutral thresholds may underestimate the health risks for the most sensitive populations.
  • The online California Heat Assessment Tool (cal-heat.org) allows users to visualize projected changes in heat events that cause adverse health impacts, while also exploring data on social, health and environmental factors that contribute to heat vulnerability.

Weathering Wildfires: 427 Interview

Director of Analytics, Nik Steinberg, discusses wildfire risk, impacts and prevention efforts, on the Midday Briefing. Nik explains implications of increasingly frequent and severe wildfires for the insurance industry and homeowners and shares several ideas for adapting to these risks. While fires have always occurred, climate change is changing the landscape of the wildland-urban interface and residents and policy-makers must understand their wildfire risks and implement preventative strategies. The economic implications are huge for utilities, shareholders and communities, but with intentional planning businesses, governments and residents have the opportunity to mitigate loss.

 

Public Health System Resilience Scorecard

Climate change will continue to adversely affect public health by threatening sanitation, altering the distribution of vector-borne disease, increasing the need for effective heat wave responses, introducing new mental health challenges and more. To help cities understand their vulnerability to these impacts and build resilience, the United Nations Office for Disaster Risk Reduction (UNISDR) developed a Public Health System Resilience Addendum for its Disaster Resilience Scorecard for cities.

The addendum includes 24 questions, defining a 0-5 scale for practitioners to quantify their responses (see example below). The questions cover the integration of public health with each of UNISDR’s Ten Essentials for Making Cities Resilient: disaster governance, disaster scenarios, finances, land use and building codes, ecosystem services, institutional capacity, societal capacity, infrastructure resilience, disaster response, and disaster recovery.

By capturing all of the possible weak spots in the broader health system, the addendum is meant to be a tool for mainstreaming public health considerations into disaster risk reduction plans, rather than just serving as a one-time assessment.  Using this integrated approach can help city officials build resilience over time. Recent events like the power outage that led to eight deaths in a Florida nursing home after Hurricane Irma demonstrate the preventable nature of many public health disasters. Ensuring that critical facilities have backup power supplies and that potential hazards are effectively communicated are ways in which effective planning can mitigate loss. By understanding existing vulnerabilities and how these will worsen with climate change, officials can implement essential adaptation measures that will save lives.

Four Twenty Seven contributed to this addendum and has developed a methodology to assess climate risk exposure in U.S. cities and counties. We are continuing research on quantifying local resilience to climate impacts and supporting public health responses to climate change. The forthcoming California Heat Assessment Tool will provide public health officials with an interactive platform to understand the projected increase in extreme heat events in each California census tract, based on the sensitivity of the local populations. It will also show the distribution of frontline individuals, such as the elderly, to inform effective local heat responses. This free, user-friendly tool will be live in mid-August.
