Life in the fast lane is fun but it can quickly destroy our planet. In the U.S. alone, 20% of all greenhouse gas emissions come from cars and small trucks like SUVs, contributing to climate change, pollution, and diseases like asthma.

Fulfill your need for speed mindfully with help from our spankin' new How to Go Green: Cars guide. It's full of useful facts, stats and more importantly, solutions that will leave you feeling better about taking that long awaited road trip.

Here are some exclusive bonus tips to get you free-wheelin' towards a greener life:

- Speak up

Become an advocate for strong fuel-economy standards, better public transit, more bike lanes, better sidewalks, and more car-free areas in your city. Many communities are not designed for life without an automobile, but that can change with some good planning and political will.

- Organize your coworkers

Get a ride?sharing network going at work. (Maybe you'll even get a raise)

- Good tires

Different tires affect MPG in different ways. When you're in the market for new tires, look for the ones that help give you the best mileage. (And don't forget about proper inflation!)

- If you're the boss

If you are an employer, there's almost no limit to the things you can do to encourage greener driving from your employees. A growing number of bosses are using rewards and perks to encourage employees to rideshare and drive hybrids or other fuel-efficient cars. You can also subsidize passes for public transit, make your office bike friendly (anything from having good bike racks to having showers), and set a good example with your own transport choices. Facilitating telecommuting can also save on fuel, emissions, and time wasted commuting.
