Tracking carbon impact
The OCO-2 mission, which launched in July 2014, is designed to provide a better idea of how carbon is contributing to climate change.

Findings
Satellite data combined with surface-based observations provided information on carbon dioxide emissions and absorption by forests and other carbon-absorbing "sinks" in countries.

Map
NASA's map illustrates net carbon dioxide emissions and removal from 2015-2020. Countries with higher emissions are marked in shades of tan or brown.
