From global to national GHG budgets: the REgional Carbon Cycle Assessment and Processes-3 (RECCAP3)

As human-induced climate change intensifies, there is a growing demand for more comprehensive greenhouse gas (GHG) intelligence to support the development and implementation of mitigation policies. This demand is amplified by the surge in GHG data availability, best illustrated by the proliferation of GHG monitoring satellites being launched, and by the increase in GHG reporting requirements for all countries under the Enhanced Transparency Framework of the Paris Agreement. Globally, comprehensive GHG budgets with the skill and detail to separate natural and anthropogenic GHG sources and sinks have played a critical role in supporting the development of global decarbonization pathways. Now, this type of comprehensive earth system budget is required at the national scale, where climate and energy policies are implemented, with an increasing reliance on natural carbon sinks to achieve net zero emission targets. This approach will link the global requirements for climate stabilization with national-scale mitigation efforts and biospheric changes.
