Working Group III focuses on climate change mitigation, assessing methods for reducing greenhouse gas emissions, and removing greenhouse gases from the atmosphere.

Climate change mitigation involves actions that reduce the rate of climate change.

Climate change mitigation is achieved by limiting or preventing greenhouse gas emissions and by enhancing activities that remove these gases from the atmosphere. Greenhouse gases can come from a range of sources and climate mitigation can be applied across all sectors and activities. These include energy, transport, buildings, industry, waste management, agriculture, forestry, and other forms of land management.

Working Group III supports the IPCC’s solution-oriented approach but does not advocate any specific mitigation options. It takes both a near-term perspective relevant to decision-makers in government and the private sector and a long-term perspective that helps identify how high-level climate policy goals might be met. Working Group III addresses all aspects of mitigation including technical feasibility, cost and the enabling environments that would allow measures to be taken up. Enabling environments cover policy instruments, governance options and social acceptability. Synergies and trade-offs with adaptation measures are of increasing interest as are co-benefits, risks and links to sustainable development. To meet these needs, Working Group III is highly interdisciplinary in character.

Working Group III is led by two Co-Chairs, Katherine Calvin based in the United States of America and Joy Pereira based in Malaysia. They are supported by seven Vice-Chairs from different regions who make up the Working Group III Bureau. Bureau members provide guidance to the Panel on the scientific and technical aspects of its work, advise on related management and strategic issues, and take decisions on specific issues such as the selection of authors and review editors. They also oversee scientific quality and engages with the wider scientific community, both regionally and globally. The Co-Chairs and Bureau Members are supported by the Working Group III Technical Support Unit.

Reports

Working Group III is responsible for the mitigation component of an assessment report. It also contributes to the Synthesis Report that integrates the findings of the three Working Group reports. In the sixth assessment cycle it also managed the production of the IPCC Special Report on Climate Change and Land  finalized in August 2019, and contributed to the scientific leadership of the IPCC Special Report on Global Warming of 1.5°C finalized in October 2018.

Activities

Working Group III activities include the scoping of the IPCC reports which it manages and to which it contributes, selecting authors, and planning, organising and managing Lead Author Meetings. In April 2017, Working Group III organised an expert meeting on Mitigation, Sustainability and Climate Stabilization Scenarios which strongly influenced the subsequent scoping of the Sixth Assessment Report. Working Group III Bureau members and Technical Support Unit also regularly attend conferences, workshops and outreach events, to talk about the IPCC and engage with stakeholders globally.
