You can also purchase credits for flights you take, and home usage. What's the point? Well they basically offset your carbon emissions by funding clean air sources. Neat, yea? :)
Awesome idea, and I found it VERY helpful regarding what cars to consider for having the lowest emissions. I looked at several cars, comparing mine to newer ones. Obviously, the hybrid would be the best bet, but after doing some number crunching, it isn't the most affordable bet for me either. I can actually afford a regular Civic, and something my boyfriend noted was that if finances get better next year, maybe we can trade it in for a hybrid.
*sigh* I test drove both the regular Civic and the Hybrid Civic today and oh goodness, I yearn for the hybrid WITH navigation. Why can't you be affordable?!
Here's a conversation I had with my boyfriend today in the car too which I found amusing.
HIM: Hybrid cars aren't affordable... you don't see poor people driving hybrids
ME: No, poor people take public transportation which is better.
HIM: .....
HIM: Well, you don't see lower middle class people driving hybrids.
:P
