On Monday morning, President Barack Obama signed executive orders that could speed the reduction of greenhouse-gas emissions from automobiles by improving fuel economy and setting stricter emissions standards. While the technology exists to reach the stricter standards, it's not clear that automakers can implement them fast enough. What's more, additional policy measures may be needed to reduce overall fuel consumption.
Obama signed two orders on Monday. One required the Department of Transportation (DOT) to enforce a law that will increase fuel-economy standards to a minimum of 35 miles per gallon by 2020. The law was passed in 2007, but detailed rules telling automakers how to comply were never implemented by the Bush administration. The second order signed by the president calls for the Environmental Protection Agency (EPA) to revisit a request from the state government of California asking for permission to implement emissions standards that are more strict than federal rules. Those standards call for decreasing carbon-dioxide emissions from new vehicles by 30 percent by 2016; more than a dozen other states have since followed California's example. Under President Bush, that request was denied, but experts say it's likely that the EPA will now approve it.
