US PIRG has a study about six simple steps to cutting our greenhouse gas emissions. In a nutshell, they are:
1. Drive less (and making driving less plausible)
2. Make cleaner cars (->40 mpg standards)
3. Increase percentage of biofuel, and more availability (+10%)
4. Use less electricity (-10%)
5. Get more electricity from renewable sources (->20%)
6. Don’t increase emissions in other areas
Simple? Perhaps. Possible? Certainly.
