No left turn on solid green...

The shipping company United Parcel Service did a study in 2004 and announced that their drivers would avoid making left turns. It was determined that this act will be a way to curb CO2 emissions. The reasoning behind this is that the time spent idling while waiting for oncoming traffic burns fuel. Now, for a company of this size, this fuel can become a substantial amount of millions each year. They devised a software program to map out the necessary customized routes for their drivers to minimize the left turns. Through enacting this process, in New York City, the company reduced their emissions by 1,000 metric tons in the first six months of 2007. Today, 83% of all of the UPS facilities are headed in this direction. Within 2 years the policy will become national to the company.
