What’s the Big Deal?
Cars are one of the great mixed bags of our time. They are at once wonders of engineering and a threat to life on Earth. They create convenience and comfort and also snarled traffic and sprawling suburbs. In the US, about 20% of all greenhouse gas emissions come from cars and light trucks like SUVs, contributing to climate change, air pollution, and disease. If you are truly trying to lighten your environmental footprint, the first thing to do is ask if you do in fact need a car. If the answer is yes, there are many things you can do to make your driving life greener.
