Climate Change 2022: Mitigation of Climate Change is the third part of the Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) and was prepared by its Working Group III. The volume provides an updated global assessment of current and projected emissions from all sources and sectors, mitigation options that reduce emissions or remove greenhouse gases from the atmosphere, and progress towards meeting climate ambitions. It assesses what is required to achieve net zero emissions as pledged by many countries.

This report shows that greenhouse gas emissions over the last decade are at the highest levels in human history. It shows that urgent action is needed. Unless there are immediate and deep emissions reductions across all sectors, limiting global warming to 1.5°C will be beyond reach. Global greenhouse gas emissions implied by Nationally Determined Contributions announced prior to COP26 make it likely that warming will exceed 1.5°C and will also make it harder to limit warming to below 2°C.

But there are positive signs and increased evidence of climate action. Options are available now in every sector that can at least halve emissions by 2030. Some countries have already achieved a steady decrease in emissions consistent with limiting warming to 2°C. Costs for some forms of renewable energy have fallen, use of renewables continues to rise and, in some countries and regions, electricity systems are already predominantly powered by renewables.
