In a move that has sent shockwaves through the environmental policy world, the US Environmental Protection Agency (EPA) has proposed to rescind greenhouse gas emissions standards for vehicles under the Clean Air Act. This is not merely a regulatory rollback, but a fundamental rethinking of the legal and scientific basis for environmental regulation in America.
An accompanying climate assessment report from the US Department of Energy provides the scientific rationale for the rollback. It will make for uncomfortable reading for those who think that green policy should be based on ideology rather than a clear-headed assessment of the facts, but it is a vital document for bringing clarity to a subject often clouded by dogma.
