Climate change 2022: mitigation of climate change

The report provides an updated global assessment of climate change mitigating 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. The report introduces several new components viz., a new chapter on the social aspects of mitigation, which explores the ‘demand side’, i.e. what drives consumption and greenhouse gas emissions and explores the ‘supply side’ of climate change what produces emissions. There is also a cross-sector chapter on mitigation options that cut across sectors, including carbon dioxide removal techniques. A new chapter on innovation, technology development and transfer, which describes how a well-established innovation system at a national level, guided by well-designed policies, can contribute to mitigation, adaptation and achieving the sustainable development goals, while avoiding undesired consequences.
