Action to reduce methane emissions can avoid 0.3°C of warming by 2045, according to UNEP. While reduction in fossil fuel methane emissions is both vital and achievable, this briefing sets out the benefits to concurrently implementing global action plans to address the role of agriculture and food systems in generating methane emissions. This briefing sets out the case for the UK Presidency of COP26 to advocate for effective demand-side food system measures to achieve major methane reductions in the agriculture sector, bringing 1.5 degrees within reach.
