Climate Risk as Investment Risk: Integrating Physical and Transition Risks

At AP7, we've moved beyond the debate about whether climate change affects investment returns. The evidence is unequivocal: physical climate risks are already impacting asset valuations, and the transition to a low-carbon economy is creating both risks and opportunities across every sector. Our climate risk framework distinguishes between three time horizons. In the near term (1-3 years), regulatory risk dominates. Carbon pricing mechanisms now cover 23% of global emissions, up from 5% in 2015. Companies with high carbon intensity face increasing compliance costs that directly impact margins. Our analysis shows that a $50/ton carbon price would reduce earnings by 5-15% for the most exposed sectors, including cement, steel, and conventional utilities. In the medium term (3-10 years), transition risk becomes paramount. The shift to renewable energy, electric vehicles, and sustainable agriculture is accelerating faster than most models predicted. Solar and wind are now the cheapest sources of new electricity generation in 90% of the world. Companies that fail to adapt their business models face stranded asset risk—we estimate that $2.5 trillion in fossil fuel reserves may become economically unviable under a 2°C scenario. In the long term (10-30 years), physical risk dominates. Rising sea levels, extreme weather events, and agricultural disruption will affect real estate values, supply chains, and sovereign creditworthiness. Our modeling suggests that unmitigated climate change could reduce global GDP by 10-23% by 2100, with disproportionate impacts on emerging markets. Our investment response has been multi-faceted. First, we've implemented carbon footprint reduction targets: our portfolio's carbon intensity has declined 45% since 2019, achieved through both engagement and divestment. Second, we've allocated 15% of the portfolio to climate solutions—renewable energy infrastructure, green bonds, and climate technology venture capital. These investments have generated attractive returns while contributing to emissions reduction. Third, we've developed proprietary climate scenario analysis tools that stress-test our portfolio under multiple warming pathways (1.5°C, 2°C, 3°C, and 4°C). This analysis revealed that our real estate portfolio was significantly exposed to flood risk in Northern Europe, leading us to divest from properties in high-risk zones and invest in climate-resilient infrastructure. The engagement approach has been particularly effective. Through Climate Action 100+, we've co-led engagements with 15 major emitters, resulting in science-based emissions reduction targets, improved climate governance, and enhanced disclosure. Engagement is not a substitute for portfolio action, but it amplifies the impact of our investment decisions. For fellow CIOs, my key message is this: climate risk integration is not about sacrificing returns for values. It is about incorporating a material risk factor that traditional financial analysis has systematically underpriced. The pension funds that integrate climate risk most effectively will be the best-performing funds of the next decade.
