A NASA Earth-observing satellite has helped researchers track carbon dioxide emissions for more than 100 countries. The pilot project offers a powerful new look at the carbon dioxide being emitted in these countries and how much of it is removed from the atmosphere by forests and other carbon-absorbing "sinks" within their borders. The findings demonstrate how space-based tools can support insights on Earth as nations work to achieve climate goals.
The international study, conducted by more than 60 researchers, used measurements made by NASA's Orbiting Carbon Observatory-2 (OCO-2) mission, as well as a network of surface-based observations, to quantify increases and decreases in atmospheric carbon dioxide concentrations from 2015 to 2020. Using this measurement-based approach, the researchers were then able to infer the balance of how much carbon dioxide was emitted and removed.
