So it’s 2010, and your resolutions are under way. Let me share a few items to add to your list. I’ll be undertaking each and every one of these this year and hope you’ll join me. There are many interesting notes “out there” about how if all of us undertook some small change in our lives, we can collectively make a significant impact on the world. Here are 5 of our favorites and suggestions on how to actually do something about them.

1. If every home in America replaced just one incandescent light bulb with an ENERGY STAR qualified CFL, in one year it would save enough energy to light more than 3 million homes. That would prevent the release of greenhouse gas emissions equal to that of about 800,000 cars. GE has a nice calculator on their website.

2. If we cut our weekly meat intake by 1/7 (one day meat-free) we’ll reduce our carbon footprint by over 431.2 pounds of CO2 equivalents per year. The international meat industry generates roughly 18% of the world’s greenhouse-gas emissions. Meat free recipes.

3.  If everyone drove their cars 20 fewer miles per week, it would reduce CO2 output by 107 million tons, or 9 percent of all auto emissions. Most of us could reduce our daily miles pretty easily (and save money on gas) by simply planning our drives ahead of time.

4. If just 25 percent of American homes used 10 fewer plastic bags a month, we’d save more than 2.5 billion bags a year.  Take a reusable bag to the store with you.  See why reducing plastic trash matters here.

5. If the average American reduced junk mail for 5 years, we would conserve 1.7 trees and 700 gallons of water, and prevent the associated global warming emissions. See 41pounds.org for more on how you can reduce your mail.
