Calculate Your Emissions

The first step in reducing your emissions from driving is learning about your personal contribution to the carbon dioxide (CO2) content of the air. EPA has developed tools to help individuals (and households) reduce greenhouse gas emissions and take action. Businesses and organizations interested in educating their employees and members about what they can do at home to help protect our climate can also use these tools. By using this personal emissions calculator, you can estimate your personal greenhouse gas emissions or your family’s greenhouse gas emissions, including emissions from driving.

Now that you've calculated your CO2 emissions from driving, learn more below about how to reduce your emissions through purchasing the cleanest and most fuel-efficient vehicle that meets your needs, as well as other tips for reducing vehicle emissions and fuel usage.

• The Green Vehicle Guide provides information about the environmental performance of vehicles, including emissions and fuel economy, and provides the user with dynamic search and sort capabilities. Side-by-side comparisons can be performed for up to three vehicles and searches can be customized based on user choices by using the Advanced Search function.
• The Fuel Economy Guide helps consumers make informed fuel economy choices when purchasing a vehicle and helps them achieve the best fuel economy possible from the cars they own. The site provides fuel economy estimates, energy and environmental impact ratings, fuel-saving tips, and other useful information. It is maintained jointly by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy and the U.S. Environmental Protection Agency.
