The document discusses the relationship between climate change, the environment, and the global financial system. It argues that policymakers need to take greater account of environmental factors when making decisions that impact finance and the economy. The G20 is positioned to advance this by taking three steps: 1) Asking the FSB to consider the impact of climate change on financial stability. 2) Encouraging environmental stress testing of financial policies like Basel III. 3) Exploring how central banks can green their asset purchasing activities. Aligning finance more with environmental sustainability would improve the stability of the global economic system in the long run.
