going carbon neutral

What does anyone know about going "carbon neutral"? Are any of you currently practicing this? Do you have plans to start? Do you feel its a legitimate and useful way to contribute to the fight against climate change?

I've been reading about going carbon neutral at David Suzuki's website.

Going carbon neutral is an easy way to take responsibility for the greenhouse gas emissions we create every time we drive our cars, take a plane, or turn on our computers. It's based on the principle that, since climate change is a global problem, an emission reduction made elsewhere has the same positive effect as one made locally.

Here's how it works: if you add polluting emissions to the atmosphere, you can effectively subtract them by purchasing 'carbon offsets'. Carbon offsets are simply credits for emission reductions achieved by projects elsewhere, such as wind farms, solar installations, or energy efficiency projects. By purchasing these credits, you can apply them to your own emissions and reduce your net climate impact.

Why Go Carbon Neutral?

To solve the problem of climate change, we all need to take account of our personal carbon emissions and make continued efforts to reduce them wherever possible. But it is impossible to reduce our carbon emissions to zero, no matter how hard we try. Going carbon neutral by purchasing carbon offsets is a practical and affordable way to do something about those remaining emissions.

In addition, by voluntarily calculating and assigning a cost to your carbon emissions, you can begin to prepare for the inevitability of an economy in which carbon dioxide and other greenhouse gases are regulated and taxed. Whether you are a business or an individual, this is an important step towards managing your carbon emissions efficiently and identifying potential for reductions and savings.

Purchasing high quality carbon offsets from projects such as wind farms also helps support the transition to a sustainable energy economy by providing an additional source of revenue to developers of renewable energy.

While voluntary offset programs should not be seen as a substitute for comprehensive government regulations to reduce greenhouse gases (e.g. through implementation of the Kyoto Protocol), they are a step in the right direction, and an opportunity to demonstrate leadership on climate change.

It goes on to list corporations, sports teams, huge special events, bands and other enterprises that have already gone carbon neutral. It's an impressive list. (Scroll down to "Who's Doing It".)

And I guess that's what concerns me. This sounds like an important step, and because it's David Suzuki, I'm inclined to embrace it. (Al Gore has a similar section on his website.) I'm just naturally suspicious of anything that sounds too easy. Which doesn't mean I won't do it, just that I have questions.
