Good morning, and thank you for the opportunity to speak.
Climate change is absolutely the defining challenge of the century and will give rise to increasingly severe financial risks unless we accelerate climate action. Risks include not only the cost of adapting to physical impacts, for example, increased fire and hurricane intensity, but also those related to transitioning businesses as policy-makers act to attempt to avert the worst physical aspects. Transition risks include both policy and regulatory-related transition risks, predominantly focused on decarbonizing activities, and technology-related transition risks related to changing demand patterns and consumer preferences.
Individual sectors are impacted differently by these climate-related financial risks. They are, however, all interrelated. Policy action to reduce the physical impacts on sectors such as agriculture drives policy action to decarbonize others, such as transport—for example, mandates to shift to electric vehicles. In turn, this reduces demand for oil products for transport fuels via substitution. Coal and gas are similarly impacted as electricity is increasingly generated from renewables.
Climate risks are felt by businesses across all sectors and, by extension, their investors. This is particularly so for investors with long-term liabilities invested across a broad cross-section of the market—universal owners—including defined benefit pension schemes. Given many such schemes—including four of the five largest Canadian funds by assets under management—are state-backed, climate risk is ultimately held by governments and taxpayers. Climate change must be viewed as a systemic financial risk to markets, and politicians who dismiss climate risk as a woke concern do so at their own peril.
From the Canadian economic perspective, agriculture is a big sector, highly exposed to physical impacts, while also a major fossil fuel extractor and exporting economy. As European banks increasingly turn away from fossil fuel lending, these risks are becoming concentrated within the Canadian financial system. Lower long-term demand for oil and gas exports will also impact our system.
Investors must consider the impacts of these climate-related financial risks on portfolios and use appropriate climate models and scenario analyses to do so. Pension funds should keep the methods they use to assess risks current and keep members informed on how they are managed.
Current practices in the investment industry have major shortcomings, however. A range of key players, from investment consultants to pension funds and banks, rely on economists' flawed research to map warming to future GDP damages, informing investment decisions as well as supervisory stress tests. Such economists' work is generally self-referential, generally ignoring critical feedback from climate science.
Invalid assumptions within one such model, the DICE integrated assessment model from William Nordhaus, include, one, that industries not exposed to weather will be unaffected by global warming, which also ignores the two types of transition risks I described earlier, and two, a quadratic function is appropriate to extrapolate damages, despite other functions—for example, an exponential function—equally fitting our historical data but projecting far greater climate impacts.
Such damages are likely greater for a given temperature and occur sooner in time. They will likely have a greater cost in present value terms—i.e., the financial costs are less discounted—so the benefit of climate action is underestimated within the financial system.
Carbon Tracker's report “Loading the DICE” warned that, “Following the advice of investment consultants, pension funds have informed their members that global warming of 2-4.3°C will have only a minimal impact upon their portfolios.” Another study looking at economists' projections suggested a 5°C world would lower GDP by 10% and a 7°C world by just 20%, which cannot conceivably be reconciled with climate scientists' warnings that such temperature rises will be an “existential threat” to human civilization.
Ultimately, financial institutions, central banks, regulators and governments have all been misled by such models, underestimating the dangerous and likely economic damages of climate change.
While that report was focused on U.K. pensions, it featured in the Canadian press and findings were applied to a number of Canadian pension funds including AIMCo, PSP, IMCO and others, where a “lack of disclosure leaves plan members [ultimately] in the dark about the pension risks of climate change”.
Furthermore, a review of 2023 Task Force on Climate-related Financial Disclosures reports of leading pension funds found many others were lacking in terms of their climate disclosures, particularly around client choice of scenarios and climate risks being presented.
We see a number of areas for potential regulatory interventions. These focus on investors, investment consultants, the economist community and a consideration to require corporates to publish transition plans—as, for example, the U.K.'s transition plan task force and the EFRAG guidance in the European Union.
