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.
