The Green Swan Toolkit

The Green Swan Toolkit argues that current financial policy frameworks are insufficient to address the "radical uncertainty" of climate change. It advocates for a precautionary approach to risk, the adjustment of Pillar I capital requirements to account for fossil fuel asset stranding, the use of macroprudential systemic risk buffers, and the mandatory integration of 1.5°C-aligned climate criteria into bank financing decisions via Pillar II requirements.

• Current climate risk policies relying on disclosures, scenario analysis, and stress testing are limited because climate risks involve "radical uncertainty", making "efficient" price discovery impossible and biasing concerns toward short-term market disruption over long-term catastrophic risks.
• To limit global warming to 1.5°C, fossil fuel production must decrease by an average of 6% annually until 2030, meaning 84% of known reserves must remain unexploited. Current EU regulations, such as the Capital Requirements Regulation (CRR) and Solvency II Directive, do not treat fossil fuel exposures in a way consistent with this risk of asset stranding.
• Climate change is a source of systemic risk that should be addressed through macroprudential frameworks, specifically by implementing systemic risk buffers under the Basel Framework to require higher capital from the most exposed financial institutions.
• Financial regulators should mandate that banks adopt climate targets aligned with a 1.5°C trajectory and develop 5-year transition plans, potentially linking these metrics to Pillar II capital requirements to account for the risk of activities that contradict the Paris-aligned transition.
