Nothing will advance our plan faster than bold and ambitious policies. The next set of global actions must accelerate the world’s transition to clean energy while defining how each country will tackle the challenge. Countries must simultaneously signal their long-term plans while taking more immediate steps to make net zero possible by 2050.
Which policy changes have the most impact? At COP30, the 2025 climate summit in Brazil, countries will declare updated commitments to cut greenhouse gas emissions. Between now and then, they must adopt more aggressive policies, from transformational legislation to stringent emissions standards for power plants, vehicles, buildings, and factories. We call upon nations to end direct subsidies for fossil fuels and to set a meaningful price on carbon. Finally, they must curb emissions from methane, which has eighty times more near-term warming power, pound for pound, than carbon dioxide. These efforts need to be supported by expanded government funding for research and development.
