Transportation

Avoid conventional antifreeze, which is highly toxic. Buy antifreeze made from propylene glycol, which is lower in toxins and biodegradable, or recycled antifreeze. As a last resort, you could buy an "extended life" product that will last for five years or 150,000 miles. It's toxic, but because you'll use less, it's preferable to conventional antifreeze, which generally has to be replaced every thirty months or 30,000 miles. Whichever antifreeze you choose, recycle it at the end of its useful life. Many auto repair shops will recycle antifreeze on-site, or remove the antifreeze and send it to another location for recycling.

Try public transportation for one week. There are considerable advantages to you as well as the environment. You can save on gas, maintenance costs, parking fees, parking tickets and possibly insurance premiums. You won't have to worry as much about accidents, vehicle wear and tear, vandalism or theft. You won't have to deal with tolls, traffic, bad drivers or parking. You can catch up on reading or pass the time with a hobby, like knitting, during the ride.

Explore your carpool opportunities. Type up a notice stating you are interested in discussing carpooling and post it in approved areas at work, school or wherever you are commuting to. Make sure you pick your carpool buddies carefully; interview each candidate for personal, geographical and schedule compatibility.
