Sign up for Slate’s Green Challenge.

Much of the discussion around climate change involves national and international policy–should the United States sign the Kyoto Treaty or increase auto efficiency standards? But even without major political or legislative changes, there’s a lot that concerned individuals can do to make the problem better. To that end, we’ve created the Slate Green Challenge–a straightforward program to evaluate and reduce your carbon emissions between now and the end of the year.

First, you’ll take a quiz to assess your annual emissions. Next, Slate and treehugger.com will put you on an eight-week “carbon diet”–the goal being to reduce your contribution to global warming by at least 20%.

I’m down to participate. Who’s with me? I hear we’re still allowed to eat (locally produced) ice cream.
