Embedded in Nature: Nature-Related Economic and Financial Risks and Policy Considerations
Charlotte Gardes-Landolfini, William Oman, Jamie Fraser, Mariza Montes de Oca Leon, and Bella Yao
The economy is embedded in, and dependent on, nature. Yet economic activity is degrading nature at an unprecedented pace. Interacting with climate change, nature loss and transformation generates significant threats to the global economy and financial system. However, work on the implications of nature-related risks for macroeconomic and financial sector policies remains at an early stage. This note seeks to contribute to this emerging policy space in three main ways: (i) it proposes a conceptual framework for understanding nature-related risks by mapping out macroeconomic transmission channels, emphasizing their impact on the economy and financial systems through “double materiality;” (ii) it conducts empirical analysis, finding that nearly 38 percent of bank loans of the 100 largest global banks are to harmful subsidies-dependent sectors and 44 percent are exposed to conservation areas under the Global Biodiversity Framework, and that industries most exposed to nature degradation are not well prepared to manage these risks; and (iii) it discusses takeaways for macroeconomic and financial sector policies and frameworks.

Energy Transition and Geoeconomic Fragmentation: Implications for Climate Scenario Design
Charlotte Gardes-Landolfini, Pierpaolo Grippa, William Oman, and Sha Yu
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.

Cross-Border Risks of a Global Economy in Mid-Transition
Etienne Espagne, William Oman, Jean-François Mercure, Romain Svartzman, Ulrich Volz, Hector Pollitt, Gregor Semieniuk, and Emanuele Campiglio
This paper analyzes the cross-border risks that could result from a decarbonization of the world economy. We develop a typology of cross-border risks and their respective channels. Our qualitative and quantitative scenario analysis suggests that the mid-transition – a period during which fossil-fuel and low-carbon energy systems co-exist and transform at a rapid pace – could have profound stability and resilience implications for global trade and the international financial system.

Climate Action to Unlock the Inclusive Growth Story of the 21st Century
Amar Bhattacharya, Maksym Ivanyna, William Oman, and Nicholas Stern
Climate change is a major threat to the sustainability and inclusiveness of our societies, and to the planet’s habitability. A just transition to a low-carbon economy is the only viable way forward. This paper reviews the climate change challenge. It stresses the criticality of systems changes (energy, transport, urban, land use, water) in a climate-challenged world, and the importance of infrastructure investment geared toward such systems changes. The key policies to enable the transition are: public spending on and investment frameworks for sustainable infrastructure, pricing carbon, regulations, promoting sustainable use of natural resources, scaling up and aligning finance with climate objectives, low-carbon industrial and innovation policies, building resilience and adaptation, better measurement of well-being and sustainability, and providing information and education on climate risks. Implemented well, climate action would unlock the inclusive growth story of the 21st century, making our societies more sustainable, inclusive, and prosperous.
