The United States is one of the world’s biggest emitters of greenhouse gases, accounting for 25% of global emissions. Within the U.S., emissions from transportation sources represent about a third of the nation’s total emissions, and have accounted for nearly half of the net increase in U.S. emissions since 1990.

Americans rely on transportation sources of all types to go about their daily lives, but with the amount of greenhouse gases our vehicles emit even small changes could help reduce our collective carbon footprint. While using your car or taking a flight may seem like the most convenient way to travel, you may discover that you can save time, money, and stress by choosing a lower greenhouse gas-emitting option.
