An analysis released at the Cop30 climate summit in Belém, Brazil, suggests that adhering to three major climate commitments—tripling renewable energy capacity, doubling global energy efficiency, and significantly reducing methane emissions—could prevent nearly 1°C of additional global warming this century. The Climate Action Tracker coalition estimates that achieving these goals could lower projected warming from 2.6°C to about 1.7°C, aligning more closely with the Paris Agreement’s 1.5°C target. Among G20 nations alone, these measures could reduce greenhouse gas emissions by 18 billion tonnes by 2035, cutting the rate of global heating by one-third in the next decade. However, experts warn that implementation remains uncertain, particularly regarding methane reductions, as many countries underreport emissions and face pressure from fossil fuel industries. The Cop30 summit is focusing on translating existing pledges into action and developing a roadmap for phasing out fossil fuels, though resistance from major petrostates remains a challenge.
