Global methane emissions
New insights from the GAINS team have revealed important contributions from global oil production. Combined with increased shale gas extraction in the US and Canada, and coal production in China, these activities would significantly contribute to the expected doubling of global methane emissions by the mid-century, unless effective action is taken to limit emissions as well as the use of fossil fuels. The scope for future reductions at low costs is found the greatest in the fossil fuels and waste sectors, with methane emissions from enteric fermentation in livestock posing the greatest challenge in terms of technical reduction potential.
