10 out of 10

An article in today’s paper discussed your carbon footprint. They talk about some cars, and how each one gets an EPA “greenhouse gas score” out of 10 (higher is better). A GMC Yukon gets a 3 out of 10; a Prius gets 10 out of 10.

A perfect score? For a car which only reduces greenhouse gas emissions by a 1/3 compared to a behemoth SUV?

A bicycle should be 10/10. Walking should be 10/10. A fuel-cell car with hydrogen generated from a solar source should be 10/10. But the Prius is far from perfect, and it’s doing us all a disservice to pretend that’s the best we can do.
