The Climate Neutral Network has certified the Bonneville Environmental Foundation (BEF) and its renewable energy products as Climate Cool. The certification is designed to recognise businesses and programs that have achieved a net zero impact on global warming, with at least 60% of their emissions reductions coming from cuts in fossil fuel use. The BEF, which sells green tags from new renewables and offers an on-line emissions calculator, was recognised along with the 2002 Winter Olympic Games and Norm Thompson, a US catalogue retailer. Oregon Senator Ron Wyden congratulated the organisations for "demonstrating the kind of creativity and commitment that are absolutely necessary to beat global warming before it beats us." BEF's on-line calculator helps individuals and small businesses determine the greenhouse gas emitted as a result of their choices in electricity use, heating and transportation. Users can then offset all or part of those emissions through a tax deductible donation to BEF, which it will use to buy and retire green tags associated with new renewable energy projects. The Climate Neutral Network is an alliance of companies committed to developing products that reduce their impact on the earth's climate.
