Those of us who would like to be more environmentally friendly are getting more and more chances to practice this as time goes on. Many people would also like to jump on the environmentally friendly bandwagon, additional companies begin offering us the choices that we have been looking for. One example of this is the availability of green cars as rental cars.
It used to be that you had a few choices when you went to the cheapest car rental agencies. You could just pick the category of the vehicle that you wanted, without any way of determining which cheap car hire would be better for the environment. These days many of these companies offer categories such as hybrid or electric cars as well as your basic economy, compact, and luxury car hire selections. Doing a quick research through the offerings of the airport rent a car agencies should turn up at least one company with this option in most cases.
Keep in mind that even though green car rental is now a possibility, the number of these cars that are available for car hire are still relatively few. This might mean you will need to do your planning and reserve one from the cheap car hire agency way in advance of your vacation to avoid the chance of them already being claimed by other environmentally friendly travelers.
In the case of not being able to get one of these green cars, you can still help the environment by getting the most fuel efficient model available from the agency. Try to find a company that lets you specify which of the holiday car rental options you would want, rather than one that only lets you select the class of vehicle. If you cannot do this, just rent the smallest car that will fit your needs and you will have a good chance of getting the most fuel efficient option available from the agency you use.
