MADISON, Wis. -- Wisconsin is designating next weekend's homecoming football game with Illinois as "carbon-neutral."

The designation gives the university a chance to raise awareness of environmental issues, such as the damaging effects of carbon dioxide and the benefits of recycling.

The university will provide information on ways fans can take action in their daily lives to become more environmentally friendly.

It also will use an anonymous donation to buy carbon credits to offset estimated game-day carbon dioxide emissions.

The university will work with the nonprofit Delta Institute Carbon Offset Program to buy credits on the Chicago Climate Exchange. When credits are purchased on the exchange, the money is invested in other projects to offset emissions by a corresponding amount.
