There are many options when it comes to buying a climate-friendly car, and in every state, the top car is a four- or five-leaf car. That means that over 100,000 miles of driving, these cars produce fewer than 31.7 tons of CO2. In 12 of those states at least one car achieves a five-leaf rating, meaning those cars produce fewer than 18.4 tons of CO2 over 100,000 miles of driving.

Moreover, across the U.S. greenhouse gas emissions from transportation account for about one third of the national total. Choosing a more climate-friendly and low-emissions vehicle is one important way individuals can reduce their carbon footprint, and can help contribute to reducing our country’s total greenhouse gas emissions.
