A policy promoting cost-effective, low-carbon "homegrown" fuels as alternatives to oil could benefit the US economy as well as the environment. Madhu Khanna (2009) and her colleagues propose a national Low Carbon Fuel Standard, which would provide flexibility to energy companies to meet national carbon reduction targets using any mix of fuels they want. Recognizing that the scientific consensus on climate change cannot motivate all stakeholders, they highlight the standard as "a major win for American consumers, businesses, and farmers, with large positive effects on our economy and our national security in the long run."
