Overview
- The new UNEP/CCAC assessment finds methane emissions are still increasing, with current legislation pointing to about a 5% rise by 2030 and 21% by 2050 versus 2020.
- Full delivery of countries’ stated plans would cut 2030 methane roughly 8% below 2020 levels, far short of the Global Methane Pledge’s 30% goal.
- Ministers in Belém called for mandatory rules, tighter measurement and faster deployment across energy, agriculture and waste to close the implementation gap.
- The report identifies the energy sector as holding about 72% of cost-effective mitigation potential through steps such as leak detection, repair and curbing venting and flaring.
- Independent trackers foresee roughly flat emissions this decade absent stronger action, while meeting the pledge could avoid about 0.2°C of warming by 2050.
