NASA Space Mission Takes Stock of Carbon Dioxide Emissions by Countries, A pilot project has estimated emissions of carbon dioxide
) 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.
This animation shows yearly fossil fuel emissions by more than 100 countries from 2015 to 2020. Countries with high emissions, including the U.S. and China , appear to pop from the page, compared to those with lower emissions. Credit: NASA’s Scientific Visualization Studio,“NASA is focused on delivering Earth science data that addresses real-world climate challenges — like helping governments around the world measure the impact of their carbon mitigation efforts,” said Karen St.
This is why developing a database of emissions and removals via a top-down approach could be especially helpful for nations that lack traditional resources for inventory development, the study authors assert. In fact, the scientists’ findings include data for more than 50 countries that have not reported emissions for at least the past 10 years.
