Industry (23% of 2021 greenhouse gas emissions) – Greenhouse gas emissions from industry primarily come from burning fossil fuels for energy, as well as greenhouse gas emissions from certain chemical reactions necessary to produce goods from raw materials.79% of our electricity comes from burning fossil fuels, mostly coal and natural gas. Electricity production (25% of 2021 greenhouse gas emissions) – Electric power generates the second largest share of greenhouse gas emissions and includes emissions from electricity production used by other end use sectors (e.g., industry).Over 94% of the fuel used for transportation is petroleum based, which includes primarily gasoline and diesel. Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes. Transportation (28% of 2021 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions.The primary sources of greenhouse gas emissions by economic sector in the United States are: Greenhouse Gas Emissions and Sinks: 1990–2021. All emission estimates from the Inventory of U.S. This net sink is not shown in the above diagrams.

Land Use, Land-Use Change, and Forestry in the United States is a net sink and offsets 12% of these greenhouse gas emissions. greenhouse gas emissions. More information is also in the electricity end-use emissions section of this page. Also, if emissions from electricity use are allocated to the industrial end-use sector, industrial activities account for a much larger share of U.S. Greenhouse gas emissions from commercial and residential buildings increase substantially when emissions from electricity end-use are included, due to the relatively large share of electricity use (e.g., heating, ventilation, and air conditioning lighting and appliances) in these sectors. Percentages may not add up to 100% due to independent rounding. Total Emissions in 2021 are 6,340 Million Metric Tons of CO₂ equivalent.
