Non-state and subnational actions that contribute to climate change mitigation are becoming increasingly important and need to be explicitly considered by countries when they determine their national contributions.

The Non-State and Subnational Action Guide facilitates the integration of the impacts of actions by entities such as states, regions, cities, and businesses into national GHG projections and mitigation assessments. While monitoring historic emission developments automatically reflects all emission reductions efforts undertaken within nation-states, including those driven by non-state actors, developing accurate projections requires that non-state actions be explicitly taken into account.

The Non-State and Subnational Action Guide provides tools for the integration of non-state actors’ activities including how to account for the variety of non-state and subnational actions undertaken by regions, cities, companies and/or sectors; assess the extent to which those actions are a means towards achieving or surpassing national climate targets; and reflect the impact of those actions in national GHG projections, policy development, and target setting.

The Non-State and Subnational Action Guide is applicable across sectors.
