Even if you don’t drive a fuel-efficient vehicle, you can still work to make your car greener.

Clean out your trunk: Carrying around too much stuff in your trunk can weigh your car down and result in your car needing to work harder to move. Lessening the load in the trunk can help your car run better.

Take care of your tires: Make sure your tires are well maintained and properly inflated. Driving on under-inflated tires can make your car less fuel efficient. Check your car’s owner’s manual to determine the proper levels your car should be at.

Slow down: How you drive can have a big impact on your car’s fuel efficiency. Accelerating and stopping quickly can waste gas. Instead, try to drive at a speed where you don’t regularly have to slam on the breaks to stop, and try to create situations where you can coast before coming to a complete stop.

Car pool: Instead of making changes to your car or the way you drive, consider changing who you drive with. Driving in a car pool will make your commute to work more energy efficient, as you are reducing the number of cars on the road.

Public transportation: If you can’t find people to car pool to work with, you can also take public transportation, like the bus.
