by Alec C. Zacaroli and Peter C. Condron (June 2008; 13 pages) The prospects for new regulations on greenhouse gas emissions have evolved from a possibility to an inevitability, according to the authors of this article. They say the greatest potential for new regulations on greenhouse gas emissions is emerging from existing laws--most particularly, the Clean Air Act. The authors, noting that state regulatory efforts and successes in the courts have set the stage for more comprehensive regulation at all levels, recommend companies position themselves to address GHG emissions by developing comprehensive climate change strategies.
