This briefing summarises key outcomes from the G20 hosted by South Africa in 2025 relevant for responsible investors with an interest in multilateral sustainable finance policy developments.

The G20 is the leading forum for international economic cooperation, bringing together major advanced and emerging economies to address global challenges such as financial stability, sustainable development, and climate action. Each Presidency culminates in a Leaders’ Declaration that reflects shared commitments and guides global policy direction. In 2025, South Africa’s Presidency placed an emphasis on linking climate action with economic resilience and financial stability. This briefing highlights the key areas where continued progress is needed as attention shifts to the next G20 cycle and evolving global dynamics.
