Researchers have discovered that carbon-rich permafrost is thawing at increasingly high rates, likely as a result of human-induced climate change, making the Arctic an important potential source of methane emissions.

The mission of the Compton Gamma-Ray Observatory was to study gamma-ray emissions in not only our galaxy, but other galaxies beyond ours.

Algeria should reduce its greenhouse gas emissions.

Carbon emissions trading has yet to take off in earnest.

Because their rapid pulse of radio emission is so predictable, a large array of well-understood pulsars can be used to measure extremely subtle abnormalities, such as gravitational waves.

The Biden administration is promoting a plan to boost electric bus production, proposing $45 billion spending to reduce American-made bus emissions to zero by 2030.

In 2011, the Administration finalized fuel economy standards for Model Year 2014-2018 for heavy-duty trucks, buses, and vans. This will reduce greenhouse gas emissions by about 270 million metric tons and save 530 million barrels of oil.

In March 2014, the Administration released a Strategy to Reduce Methane Emissions from landfills, coal mining, agriculture, and oil and gas systems through voluntary actions and common-sense standards.

One fourth of the world's carbon dioxide emissions are from the United States. Its per-capita emissions are also the highest in the world.

The differing volumes of carbon emissions are plotted in the graph below.
