An August 21 WYPR Midday With Dan Rodricks podcast discusses Maryland’s Greenhouse Gas Reduction Plan, which aims to reduce the state’s greenhouse gas emissions by 25% of its 2006 levels by 2020.  From the podcast description:

Is it a plausible plan or window dressing for O’Malley’s presidential ambitions? How will the state implement the plan? How will it affect consumers and businesses? Our guests: David Costello, deputy secretary for the Maryland Department of the Environment; Tommy Landers, policy director for the Maryland, DC Chesapeake Climate Action Network; and Kim Burns, president of Maryland Businesses for Responsive Government.
