Sources of Greenhouse Gas Emissions | US EPA

The increase in CO 2 emissions from fossil fuel combustion was a result of multiple factors, including increased energy use due to greater heating and cooling needs due to a colder winter and hotter summer in 2018 compared to 2017. Note: All emission estimates from the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2018.

Fact Sheet | Climate, Environmental, and Health Impacts of Fossil Fuels

When fossil fuels are burned, they emit greenhouse gases like carbon dioxide that trap heat in the earth''s atmosphere and contribute to climate change.

Burning of fossil fuels

Fossil fuels form over millions of years from the burial of photosynthetic organisms, including plants on land (which primarily form coal) and plankton in the oceans (which primarily form oil and natural gas). To grow these organisms removed carbon dioxide from the atmosphere and the ocean, and their burial inhibited the movement of that carbon through the carbon cycle.
