Climate Change 2022: Mitigation of Climate Change

The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.

Summary for Policymakers

The Summary for Policymakers (SPM) provides a high-level summary of the key findings of the Working Group III Report and is approved by the IPCC member governments line by line.

Technical Summary

The Technical Summary (TS) provides extended summary of key findings and serves as a link between the comprehensive assessment of the Working Group III Report and the concise SPM.

Full Report

The 17 Chapters of the Working Group III Report assess the mitigation of climate change, examine the sources of global emissions and explain developments in emission reduction and mitigation efforts.

The Technical Summary (TS), the full Report Chapters, the Annexes and the Supplementary Materials are the Final Draft versions, and remain subject to revisions following the SPM approval, corrigenda, copy-editing, and layout. Although these documents still carry the note from the Final Government Distribution “Do Not Cite, Quote or Distribute” they may be freely published, as the report has now been approved and accepted.
