Transportation’s Role in Greenhouse Gas Emissions
The Transportation sector is the second largest contributor to greenhouse gas emissions in the United States. The majority of these emissions are carbon dioxide (CO2) resulting from the combustion of petroleum-based products (i.e. gasoline and diesel), but also include smog-forming compounds, particulate matter, and other air pollutants.
Sources of transportation-related greenhouse gas emissions include:
- Passenger cars
- Light-duty trucks
- Commercial aircraft
- Ships and boats
- Trains
Reducing the use of petroleum-based products could reduce the emissions that impact air quality and public health.
