Global methane action pays for itself at least six times over

The authors of this paper provide a comprehensive economic assessment of global methane abatement, quantifying both benefits and costs. The study improves on prior work by incorporating recent climate modeling, country-level damage estimates, and the effects of climate tipping points. The authors anchor their analysis on methane scenarios consistent with the Global Methane Pledge, using an integrated assessment model (IAM) to capture the impact of methane abatement on global temperatures, economic damages, and key tipping elements such as ice sheets and ocean currents. In addition to modeling climate-related benefits, the authors include improved air quality from reduced methane-driven ozone, and we evaluate abatement costs using detailed sectoral estimates from the Global Methane Assessment.
