One of the ways for us all to ‘vote’ for reducing global warming is to choose the most fuel-efficient vehicle we can.  This is especially true when we are purchasing a car, new or used. 

It also applies to each trip we make in a vehicle if we have more than one vehicle to choose from.  Always choose the most fuel-efficient vehicle you can for any task or trip.  That’s usually the smallest one.  This works for individuals or families that have more than one vehicle.  It also applies to rental situations.
