Stop Global Warming has a list of personal actions you can take to reduce your carbon footprint. Here are a few which I think are particularly interesting and relatively painless.

Use Recycled Paper
Make sure your printer paper is 100% post consumer recycled paper. Save 5 lbs. of carbon dioxide per ream of paper.

Fill the Dishwasher

Run your dishwasher only with a full load. Save 100 lbs. of carbon dioxide and $40 per year.

Buy Products Locally

Buy locally and reduce the amount of energy required to drive your products to your store.

Plant a Tree

Trees suck up carbon dioxide and make clean air for us to breathe. Save 2,000 lbs. of carbon dioxide per year.

Air Dry Your Clothes

Line-dry your clothes in the spring and summer instead of using the dryer. Save 700 lbs. of carbon dioxide and $75 per year.

Buy Organic Food

The chemicals used in modern agriculture pollute the water supply, and require energy to produce.

Be a Meat Reducer

The average American diet contributes an extra 1.5 tons of greenhouse gases per year compared with a vegetarian diet. Eliminating meat and dairy intake one day a week can make a big difference.

My Notes:

If you plant a fruit tree, you are cutting the carbon footprint of transporting some of your food down to zero.

You can partially dry clothes in the dryer, and then hang them up on hangers indoors year around. You get some of the energy savings, and you get fewer wrinkles.

Eating some tofu and texturized soy protein (TSP) instead of meat also adds variety to your diet. Diversifying diet is generally a health boost in addition to a flavor boost.
