Green Tips

Bad news: your car is probably the single-biggest contributor to your environmental footprint. Good news: choosing a hybrid, diesel, or flex-fuel car as well as adjusting your driving habits can have a profound impact on the earth and on your wallet. In an age of astronomical fuel prices, it's helpful to remember that the little things—keeping tires properly inflated, rethinking your commute, greening rented wheels—can quickly add up.
