Many of our daily activities—such as disposing of waste, driving cars, and using electricity—cause greenhouse gas emissions. Combined, these emissions make up a household’s carbon footprint.
The EPA, businesses, and individuals all have significant roles to play. We can reduce the intensity of the consequences of climate change by taking action to reduce emissions of the greenhouse gas pollution that warms our planet.
What You Can Do to Reduce Your Emissions on the Road
The following emissions factors are based on the EPA’s estimate of the average annual emissions and fuel consumption for gasoline-fueled passenger cars and light trucks in the United States.
Cost savings for reducing the number of miles driven can be calculated using the rate of 20 cents per mile, which includes the costs of gas, oil, and maintenance. 1
Properly inflating tires increases fuel efficiency by 3 percent, and keeping your engine properly tuned improves fuel efficiency by 4 percent. 2
Performing regular maintenance on your vehicles increases fuel efficiency by 7 percent. 3
Cost savings for purchasing a more fuel-efficient vehicle can be calculated using the rate of $3.68 per gallon of gas. 4
