Use More Right Turns
Emission Reduction: Several hundred pounds of CO2 over the course of a year. It makes complete sense if you think about it. Turning right is often the easiest, quickest, and most convenient way to get around the city under the current U.S. rules of the road. It involves less wait, you don't have to worry about oncoming traffic (although you do have to watch for pedestrians), and you don't have as strict of traffic light rules to obey (unless you see the sign: "No Right On Red").
