Climate Commitments Could Cut Nearly 1°C From Global Warming, Report Finds
………..

Fully implementing three key climate pledges could substantially slow global warming, according to an analysis presented at the Cop30 summit, as reported by The Guardian. The Climate Action Tracker coalition indicates that meeting commitments on renewable energy, energy efficiency, and methane reduction could reduce projected temperature increases this century by about 0.9°C.

Countries have agreed to triple renewable energy generation and double energy efficiency by 2030, alongside significant methane cuts. If realized, these measures could lower global emissions by 18 billion tonnes by 2035 among G20 nations, sharply reducing the rate of warming over the next decade. Bill Hare, chief executive of Climate Analytics, described the impact as a “gamechanger,” potentially bringing global temperature rise down from 2.6°C to roughly 1.7°C.

This scenario would bring the world closer to the 1.5°C target of the Paris Agreement. However, other goals, such as stopping deforestation, remain unmet, threatening natural carbon sinks. Hare emphasized that the agreements are already in place and now require urgent action for implementation.

Investment in renewable energy continues to rise, exceeding $2 trillion last year, with China and India leading in solar and wind development. Methane reduction, however, faces delays, with emissions still increasing and some major emitters underreporting. While over 150 nations have pledged cuts, achieving the 2030 target remains uncertain.

At Cop30 in Belém, negotiators are expected to discuss draft proposals for phasing out fossil fuels and addressing gaps between current plans and climate targets. Experts say that fulfilling the three core pledges would accelerate the energy transition and help reduce fossil fuel use by the mid-2030s.
