Climate: Pew Center's Judi Greenwald analyzes Northeastern states' cap-and-trade plan

Seven Northeastern states are finalizing a greenhouse gas cap-and-trade plan, which will affect hundreds of fossil fuel-burning power plants in the region, beginning in 2009. But will the Regional Greenhouse Gas Initiative mean higher electricity costs for consumers and businesses? How far can renewable energy sources and energy efficiency go toward meeting proposed emissions cuts? And is the RGGI effort compatible with emerging climate policies in other states? During today's OnPoint, Judi Greenwald, director of innovative solutions at the Pew Center on Global Climate Change, weighs in on what is happening in the Northeast.
