The Intergovernmental Panel on Climate Change has released its final installment of the Sixth Assessment Report, Working Group III’s report on the global assessment of climate change mitigation progress and pledges “Climate Change 2022: Mitigation of Climate Change” (the Report). It also released an accompanying Summary for Policymakers and Technical Summary. The Report considers and documents the scientific, technological, environmental, economic, and social aspects of mitigation of climate change and notes the growing role of non-state and sub-national actors including cities, businesses, Indigenous Peoples, citizens, transnational initiatives, and public-private entities in addressing the impacts and causes of climate change. The Report has been highly anticipated and is the first mitigation report that the IPCC has published since 2014. It provides an unprecedented level of scientific analysis on the options to mitigate climate change, including a significant focus on carbon dioxide removals and the costs of emissions reductions. This bulletin briefly highlights key findings of the Report. Recent developments and current trends. The Report notes that: Total greenhouse (GHG) emissions continued to rise during the period 2010–2019, largely attributed to urban areas, and that the average annual GHG emissions during 2010–2019 were higher than in any previous decade. Reduced emissions from industrial processes and fossil fuels have been more than offset by increased emissions from rising global activity levels in industry, energy supply, transport, agriculture, and buildings. Global GHG emissions in 2030 associated with the implementation of nationally determined contributions (NDCs) announced prior to COP26 make it likely that warming will exceed 1.5°C during this century. Policy, cost, deployment of low-emission technologies and finance. The Report notes that: The cost of low-emission technologies such as photovoltaics, onshore and offshore wind, concentrating solar power, and batteries for passenger electric vehicles (EVs) has continued to decrease since 2010, as demonstrated by an over…
