After months of debate and millions of dollars in lobbying, a House panel has approved a climate and energy bill to reduce greenhouse gases. While several environmental groups have welcomed the bill, others remain critical of its concessions to the coal, nuclear, gas and oil lobbies, the scaling back of the greenhouse gas reduction target, and the giving away of the majority of pollution credits for free, instead of auctioning them. We host a discussion with Tyson Slocum of Public Citizen and Dan Lashof of the Natural Resources Defense Council.
