Next time you’re travelling, think about what you’re carrying. Any extra weight causes extra strain on the vehicle you’re in, which in turn burns more fossil fuels. Lighten your load as much as you can.
When driving,for example, take out of the car whatever you don’t need. Take the extra seats out of your van if you’re not using them. Weight is the single most significant contributor to fuel usage; for every hundred pounds in cargo, you lose between one and two percent of fuel economy. Even carrying wet or heavy snow will make a difference—be sure to clean all accumulated snow and ice off your car before driving.
Leaving unused ski-, bike-, or roof-racks on your car will not only add unnecessary weight, but will also contribute to drag, which reduces your car’s efficiency as well.
