- Transportation (28% of 2021 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions. Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes. Over 94% of the fuel used for transportation is petroleum based, which includes primarily gasoline and diesel.2

Burning fossil fuels like gasoline and diesel releases carbon dioxide, a greenhouse gas, into the atmosphere. The buildup of carbon dioxide (CO2) and other greenhouse gases like methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons (HFCs) is causing the Earth’s atmosphere to warm, resulting in changes to the climate we are already starting to see today.
Greenhouse gas (GHG) emissions from transportation account for about 29 percent of total U.S. greenhouse gas emissions, making it the largest contributor of U.S. GHG emissions. Between 1990 and 2021, GHG emissions in the transportation sector increased more in absolute terms than any other sector.

Transport is the only sector where greenhouse gas emissions have increased in the past three decades, rising 33.5% between 1990 and 2019.
Cars major polluters
Road transport accounts for about a fifth of EU emissions.
CO2 emissions from passenger transport varies significantly depending on the transport mode. Passenger cars are a major polluter, accounting for 61% of total CO2 emissions from EU road transport.
