Countries around the world have set ambitious targets for reducing greenhouse gas emissions and, as a result, are now pursuing a breadth of mitigation actions across sectors and at all scales, from local projects to national policies. These developments make it more important than ever that countries not only identify methods to measure the impacts of these mitigation activities, but also that they capture these impacts in their national inventories to improve the accuracy of their greenhouse gas reporting. This new guide, developed by the RALI team, provides a “turn-key” approach for national inventory teams, mitigation activity implementers, and other climate change practitioners to successfully apply the Harmonization Framework to a selected mitigation activity, and can be used to improve national GHG accounting. This guide provides a six-step process a country can apply to a selected mitigation activity to align MRV methods with national inventory compilation efforts, thereby improving national GHG accounting. The Harmonization Framework is helpful for:  ·        National Inventory teams  ·        Mitigation activity implementers  ·        Other climate change practitioners
