Defunct
The Voluntary Gas Tax project operated from 2001 to 2006. In 2007 we shut down the project. We've left the old web pages posted here just for the historical record.
If you would like to contact me about this site, my e-mail address is posted on my homepage.
You can't prevent your car from contributing to global warming, but you can help mitigate the damage.
Carbon dioxide is one of the main causes of global warming, and 20% of that CO2 comes from cars. Joining the Voluntary Gas Tax is an easy way to help counterbalance your car's environmental impact.
