Short summary
Given that East Asia has the highest CO2 emissions in the world, understanding the region’s carbon uptake is essential for planning mitigation strategies. We estimated natural carbon sinks in East Asia from 2010 to 2019 using satellite observations and a chemical transport model within a Bayesian inversion framework. Natural sinks offset 13.6 % of fossil fuel emissions, indicating that emissions exceed the region's carbon uptake capacity and highlighting the need for stronger mitigation efforts.
