Accelerated climate action could boost global GDP by 0.2% by 2040 compared with current policies, a study showed on Tuesday, as delegates from 40

countries meet in Berlin to shape the agenda for the COP30 summit in Brazil later this year.



An analysis by the Organisation for Economic Co-operation and Development (OECD) and United Nations Development Programme said that well-designed climate policies not only cut emissions but could enhance efficiency, productivity and innovation -potentially raising output by an amount equivalent to the size

of Sweden’s economy.



Investing in clean energy and efficiency drives productivity and innovation, offsetting the economic impact of policy-driven price and consumption changes, the study found. Reinvesting carbon revenues could further boost GDP and build public backing for climate action, it said.
