Bonneville is a Northwest non-profit organisation that in 1999 pioneered the use and sales of green tags and uses the proceeds to buy energy from wind farms in the Pacific Northwest. Native Energy uses the money from selling wind certificates to develop wind power on the Rosebud Sioux Tribe Reservation in South Dakota.
A kick-off in Los Angeles for a campaign against global warming by the Natural Resources Defense Council (NRDC) was a hot affair made climate neutral by green tags from the Northwest's Bonneville Environmental Foundation and wind certificates from Native Energy. With music by the Rolling Stones and appearances by former President Bill Clinton and actor Leonardo DiCaprio, the free concert on February 6 to "Turn Up the Heat on Global Warming" needed large volumes of electricity for lights and amplifiers, as well as fossil fuel for travel. The purchase of green tags and wind certificates ensured the event would not impact the very thing it sought to prevent -- climate change -- by offsetting all the carbon dioxide generated by the activity. The NRDC campaign is designed to pressure Congress to take the action to fight global warming that President Bush has failed to.
