Transportation: the largest source of emissions since 2017
The transportation sector is a major contributor to US greenhouse gas (GHG) emissions. In 2022, the sector accounted for 28% of total US GHG emissions, making it the largest source of emissions. This includes the movement of people and goods by cars, trucks, trains, ships, airplanes, and other vehicles.
The largest sources of transportation GHG emissions in 2022 were light-duty trucks (37%), medium- and heavy-duty trucks (23%), passenger cars (20%), and commercial aircraft (7%). From 1990 to 2022, total transportation emissions increased, largely due to increased demand for travel. The number of vehicle miles traveled (VMT) by light-duty motor vehicles (passenger cars and light-duty trucks) rose by 47% during this period due to population growth, economic growth, urban sprawl, and periods of low fuel prices.
In 2021, CO2 emissions from transportation in the US reached 1.7 billion metric tons, the highest of any economic sector. Transportation emissions accounted for 38% of energy-related emissions in the US in 2021, again the largest share of any sector. In 2017, CO2 emissions from transportation surpassed those from electric power generation.
While the EPA has made significant progress in improving air quality, approximately 140 million people in the US lived in counties with pollution levels above the primary National Ambient Air Quality Standards (NAAQS) in 2023. Since 1990, emissions of air toxics have declined by 74%, driven by federal and state regulations and technological advancements.
The EPA's Air Emissions Sources site provides detailed information on national, state, and local emissions data, tracking a range of emissions and pollution sources, including vehicle emissions.

Fossil fuels: the most polluting sector
The burning of fossil fuels has been the primary energy source for over a century, powering vehicles, businesses, and homes. Even today, fossil fuels serve about 80% of our energy needs, with 60% of electricity in 2022 being generated from burning fossil fuels. Oil, coal, and gas are the most common fossil fuels, and their combustion has severe environmental and health consequences.
The fossil fuel sector is ranked as the most polluting industry in the world. Despite a brief decline during the COVID-19 pandemic, emissions from fossil fuels rose by 1% in 2022, reaching 40.5 gigatons of CO2. The combustion of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas that traps heat in the atmosphere, leading to global warming and climate change. In the United States, the burning of fossil fuels, especially for power and transportation, accounts for about three-quarters of the country's carbon emissions.
Fossil fuel extraction methods, such as fracking and strip mining, also contribute to environmental degradation and health issues. Fracking involves injecting water, chemicals, and sand at high pressure to fracture rock and extract oil or gas, leading to air and water pollution. Strip mining, particularly in sensitive areas like Canada's boreal forest, can release vast amounts of stored carbon.
The transportation sector, including vehicle emissions, is a significant contributor to air pollution. While regulations and technological advancements have reduced emissions from vehicles, the overall increase in vehicle miles traveled has contributed to air quality issues.
To address the climate crisis, it is crucial to prioritize decarbonizing the fossil fuel industry and transitioning to renewable energy sources. Implementing sustainable practices, improving energy efficiency, and adopting cleaner energy sources, such as solar power, are essential steps toward reducing emissions and mitigating the environmental impact of the fossil fuel sector.

Commercial and residential emissions: increased by electricity use
Commercial and residential emissions in the US come from fossil fuels burned for heat, gases used for refrigeration and cooling in buildings, and waste management. In 2022, direct and indirect greenhouse gas emissions from homes and businesses accounted for 31% of total US greenhouse gas emissions. Direct emissions from commercial and residential sources made up 13% of total US greenhouse gas emissions in 2022.
Indirect emissions from electricity use in the commercial and residential sectors contribute significantly to overall emissions. This is because buildings account for 75% of electricity consumption in the US, which is used for heating, ventilation, air conditioning, lighting, appliances, and plug loads. When indirect emissions from electricity use are considered, the commercial and residential sectors account for a much larger share of US greenhouse gas emissions.
The sources of indirect emissions are power plants burning fossil fuels to generate electricity for residential and commercial use. Direct emissions from the residential and commercial sectors are produced through the combustion of natural gas and petroleum products for heating and cooking, resulting in the emission of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Natural gas consumption accounted for 78% of direct fossil fuel CO2 emissions from these sectors in 2022.
While total emissions in the US have decreased by over 3% since 1990, emissions from the residential and commercial sectors have increased by less than 1% in the same period. In 2024, residential sector electricity use rose due to increased cooling demands, leading to a 1% increase in emissions associated with residential electricity consumption. However, overall residential sector emissions were lower due to decreased heating fuel consumption. Commercial sector emissions remained relatively flat in 2024, with a minor decrease attributed to reduced natural gas and petroleum consumption.

Food retail: food and plastic waste emissions
Food waste is estimated to account for between 30% and 40% of the food supply in the United States. This estimate is based on figures from the USDA's Economic Research Service, which found that in 2010, 133 billion pounds of food, worth $161 billion, was wasted. This amount of food waste has far-reaching environmental, societal, and economic impacts.
The USDA defines food loss as the edible amount of food post-harvest that is available for human consumption but is not consumed for any reason. This includes cooking loss, natural shrinkage (e.g. moisture loss), loss from mould, pests, or inadequate climate control, and food waste. Food waste occurs at various stages of the supply chain, from production and post-harvest handling to storage, processing, distribution, and consumption.
In 2015, the USDA and the US Environmental Protection Agency (EPA) set a goal to reduce the nation's food waste by 50% by 2030. This initiative, known as the US Food Loss and Waste 2030 Champions, includes businesses and organizations that have committed to reducing food loss and waste in their operations. The FDA is also involved in reducing food waste, providing tips and resources to help consumers, students, and parents reduce food waste at home and when eating out.
Food waste has significant environmental consequences. It wastes the water, energy, land, labour, and other resources used in its production, processing, transportation, and storage. Additionally, food waste generates greenhouse gas emissions, contributing to global warming. The production of wasted food in the US is equivalent to the greenhouse gas emissions of 37 million cars. Food waste in landfills also produces nitrogen pollution, leading to algae blooms and dead zones.
Plastic waste is another significant environmental concern in the food retail industry. Plastic packaging is commonly used to protect and preserve food products, but it can contribute to pollution if not properly recycled or disposed of. While the US has made progress in reducing pollution from manufacturing industries, the food retail industry continues to contribute to plastic waste and pollution through the use of packaging and single-use plastics.
