Thursday's traditional Thanksgiving Day football game in Detroit will be the first carbon-neutral contest in National Football League history.

Ford Field and the Detroit Lions announced Monday that they will offset greenhouse gas and carbon dioxide emissions for the Lions' 68th annual Turkey Day game.

The organizations will purchase offsets through Detroit-based Carbon Credit Environmental Services.

It's been more than a year. But, California's passage of the nation's first global warming law is still being defined. And, it will continue to evolve in the coming years as the state grapples with how to cut its greenhouse gas emissions.

The law there, which took effect on Jan. 1, 2007, sets out to reduce California's heat-trapping pollutants to 1990 levels by 2020. The state is off to a notable start by enacting rules to increase its renewable energy supply to 33 percent by 2020 as well as by creating new energy efficiency performance standards and cleaning up motor vehicle emissions.

Office Depot says that its bottom line is green. It aims to be an environmental steward among national retailers and does everything from recycle paper and ink cartridges to invest in renewable energy projects. Altogether, it has spent $20 million making its stores energy efficient while providing 4,000 in-store products that have recycled content.

Its latest forays, though, are less known. Office Depot is buying renewable energy credits to offset its energy use. Companies of all sizes have the ability to purchase blocks of green power -- energy that is then used to displace so-called brown or dirty fuels. While companies will never know what types of electrons are powering their facilities, they will know that they are guaranteeing the production of clean energy.

State and federal policymakers may be digging coal into a hole. In a first-ever, the Kansas Department of Health and Environment denied an air quality permit for two proposed coal generators based upon the expected level of carbon emissions. Meantime, a movement is afoot on Capitol Hill to limit heat-trapping emissions.

Together, the actions work to set a new tone - one that considers it vital to the nation's environmental and economic futures to regulate carbon dioxide (CO2). While not immediate, the United States is well on its way to enacting legislation that would control CO2 emissions, which most scientists say causes climate change.
