Number 45 on TIME Magazine's list of 51 Things We Can Do to only make right turns while driving. It sounds strange at first, but when you think about it, it starts to make sense. How much time do you spend sitting at green lights waiting for your chance to turn left? While you sit idling, your car is burning fuel, which wastes your money and contributes wasteful carbon to the global warming problem.
According to TIME, in 2004, UPS announced that its drivers would avoid making left turns. In metro New York, UPS has reduced CO2 emissions by 1,000 metric tons since January. Today 83% of UPS facilities are heading in the right direction; within two years, the policy will be adopted nationwide.
So plan your routes ahead of time to avoid making left turns. You could save yourself some money and do your part to fight global warming at the same time.
