Story summary

At the Cop30 climate summit in Brazil, analysis says fulfilling three promises—tripling renewable energy, doubling energy efficiency, and cutting methane—could prevent nearly 1°C warming.
If G20 countries achieve these goals by 2035, emissions could fall by 18 billion tonnes, but political will is needed to resist fossil fuel pressure.
Cutting methane remains challenging due to underreporting, and the summit aims to close the gap to the Paris Agreement’s 1.5°C target.
