The Environmental Protection Agency and the National Highway Traffic Safety Administration last week rolled out their joint standards to curb greenhouse gas emissions from cars and trucks. Federal officials predict that the regulations will increase fuel economy by 5 percent every year from model years 2012 through 2016 and conserve 1.8 billion barrels of oil. They say that the new requirements will reduce U.S. dependency on foreign oil, cut greenhouse gas emissions and help save the average car buyer $3,000 in fuel costs.
However, Senate Environment and Public Works ranking member James Inhofe of Oklahoma argued that the new standards "will not enhance America's energy security, and, in fact, will make new cars more expensive and less safe."
Are the regulations too ambitious? Should they be stricter? Do you think they're emblematic of how the administration will curb greenhouse gases -- through regulation rather than legislation? What changes would you recommend?
