June 2025: Global experts including Better Finance call on G20 to address impacts of nature loss on the global economy

49 leading international experts including Better Finane sign open letter to the G20 Sustainable Finance Working Group meeting in June urging to implement measures to address nature loss in the G20 Sustainable Finance Roadmap. As the Working Group meets next week in South Africa, experts warn that the current economic and financial systems are driving ecosystem and climate breakdown toward irreversible tipping points. G20 environment ministers have similarly highlighted how nature loss poses increasing risks to economic and financial stability.

With over half of global GDP ($44 trillion) moderately or highly dependent on nature and the entire economy ultimately reliant on it, the World Economic Forum’s 2025 Global Risks Report ranks nature loss, alongside climate change, among the top four global risks facing business over the next decade. The global costs of unsustainable practices in food, land, and ocean systems are estimated at $12 trillion—and these costs continue to rise. The G20 Sustainable Finance Roadmap has established the finance sector’s role in driving climate action. In their open letter, experts now urge the G20 to build on this foundation by integrating nature also into the implementation of the G20 Sustainable Finance Roadmap.
