Abstract:

The Working Group III of the IPCC announced the summary for policy makers and the underlying Sixth Assessment Report “climate change 2022: mitigation of climate change”, on 4 April 2022. This report comprehensively reviews state-of-the-art assessment of the scientific, technical, environmental, economic, and social issues of the mitigation of climate change by updated developments in the literature since the year 2010. It provides an important scientific basis for the scientific community to have an in-depth understanding of global GHG (greenhouse gas) emissions, emission reduction paths at different temperature rise levels, and climate change mitigation and adaptation actions in the context of sustainable development. Based on main conclusions of the report, as well as key scientific issues in terms of regional differences in GHG emissions, mitigation path classification, land use-related emissions assessment and carbon dioxide removal technology assessment, it’s proposed that China should firmly adhere to the “dual carbon” strategic goal in its climate change policies and actions, implement mitigation paths together with the vision of sustainable development, equity and poverty eradication, and accelerate research and development of core science and technology of climate change integrated assessment for enhancement of international influence and voice.
