IPCC AR6 WGIII report was published in April 2022. Similar to previous IPCC assessment reports, one of the chapters is long-term mitigation pathways, which play an important role in every assessment report process. Long-term mitigation pathways provide basis for understanding on warming levels or warming targets, and support the international collaboration on GHG mitigation. AR6 again made assessment on emission scenarios published by 2021, majority of these emission scenarios were taking warming targets in Paris Agreement. This report focused on assessment on pathways, policies, cost-benefit and linking with SDGs (Sustainable Development Goals) under the Paris Agreement warming targets. This paper presents the key findings from the Chapter 3 of the report. Achieving the warming targets in Paris Agreement, global emissions need to peak before 2025, and then make rapid decrease. Negative emission technologies are needed in future, and effective emission reductions in all sectors are essential, and the mitigation could bring negative effects on economy development.

Key words: IPCC, Mitigation pathways, AR6, Paris Agreement, Scenario
