GREEN TIP OF THE WEEK - 05/03/11

If you're going to be idling your vehicle for more than 10 seconds, shut off the engine. You'll be saving gas, saving money, and reducing polluting emissions.

Modern vehicles need only about 30 seconds of idling to warm the engine, and should then be driven off slowly to warm wheel bearings, suspension, transmission and tires.

An idling engine produces twice the amount of exhaust emissions as an engine in motion, including particulate matter, dirt, nitrous oxide, hydrocarbons, carbon monoxide and carbon dioxide.

These gases and compounds are related to asthma, allergies, cancer and climate change, causing major impacts worldwide.

It's our world. If we consume resources carefully, everyone will benefit.
