Short summary

The Paris Climate Agreement requires all parties to report CO₂ emissions regularly. Given the self-reporting nature of this system, it is critical to evaluate the emission reports with independent observation systems. Here we present the direct observations of city CO₂ plumes from space and the quantification of CO₂ emissions from these observations over the largest emitter country China. The emissions from 46 hot-spot regions representing 13 % of China's total emissions can be well constrained.
