Including and quantifying methane mitigation in NDCs is key to a better climate outcome

Long-term success requires that NDCs be aggressive in terms of ambition and comprehensive in terms of gasses and sectors covered. We call upon nations to include all GHGs in the next NDCs and specify additional ambitious quantitative contributions from methane and other non-CO₂ gasses; this is a critically important opportunity to increase overall mitigation ambition, to deliver reduced near-term warming, and to obtain important societal co-benefits.
