Will a national "cap and trade" carbon market emerge in the United States? What can the volatile experience of the European carbon market teach us? Where are the future economic and environmental opportunities in carbon finance? On January 31, 2007, Columbia Business School's Social Enterprise Club, Energy Club and Bernstein Student Leadership and Ethics Board held a panel discussion to address these and other compelling questions about carbon finance. The panel featured two executives from leading carbon trading firms, as well as a distinguished environmental scholar who discussed the opportunities and challenges in the carbon finance industry. This discussion was followed by a screening of An Inconvenient Truth, the Oscar-winning documentary about the dangers of global warming, which many hope carbon finance will help to mitigate.
