Buy clean energy certificates. Another way to help spur the renewable energy market and cut global warming pollution is to buy "wind certificates" or "green tags," which represent clean power you can add to the nation's energy grid in place of electricity from fossil fuels. For information, see Green-e. And here's an innovation that's catching on: calculate the global warming pollution associated with your everyday activities, then buy enough certificates to offset them and become "climate neutral." Two places to learn how: NativeEnergy's WindBuilderssm program and Bonneville Environmental Foundation's Green Tags program. (NRDC worked with these two groups to make our February 2003 Rolling Stones concert to raise awareness about global warming climate neutral.)
