This policy brief provides an in-depth analysis of the role of non-CO2 emissions in the context of Nationally Determined Contributions (NDCs) ambition updates. It gives an overview of the role of non-CO2 emissions for national and global climate goals and how these emissions have been covered so far in countries’ current and (where already available) updated NDCs. The report also discusses different options for updating NDCs by including non-CO2 emissions.
