The transition to a low-carbon economy, which is needed to mitigate climate change and meet the Paris Agreement temperature goals, has been affected by the supply chain and energy supply disruptions that originated during the COVID-19 pandemic, the Russian invasion of Ukraine, and the subsequent energy crisis and exacerbation of geopolitical tensions. These developments, and the broader context of the ongoing “polycrisis,” can affect future decarbonization scenarios. This reflects three main factors: (1) pullbacks in climate mitigation policies and increased carbon lock-in in fossil fuel infrastructure and policymaking; (2) the decreasing likelihood of continuous cost reduction in renewable energy technologies; and (3) the likely intensification of macroeconomic shocks amid increasing geoeconomic fragmentation, and the associated policy responses. In this context, the note assesses the implications of the polycrisis for hypothetical scenarios used to assess climate-related financial risks. Following an analysis of the channels through which these effects are likely to materialize over short- and long-term horizons and some policy implications, the note proposes potential adjustments to the design of the climate scenarios used by financial institutions, central banks, and financial sector supervisors and regulators within their risk management frameworks.

The surge in energy prices since Russia’s invasion of Ukraine has reduced the energy-intensive sector’s production in Germany, although the non-energy intensive sector’s production has held up thanks in part to firms’ efforts to improve energy efficiency. Energy prices are expected to remain elevated in the foreseeable future, compared to pre-war levels, adversely affecting firms’ productivity and thus lowering Germany’s potential output. Economic modeling suggests that this effect could be around 1¼ percent of GDP in staff’s baseline, with some uncertainty around this estimate, depending on the ultimate magnitude of the energy price shock and the degree to which increased energy efficiency can mitigate it. Policies can promote effective adjustment to the shock by increasing productivity and maintaining strong price incentives to conserve energy and invest in renewable energy production.
