The United States introduced the first emission standards for vehicle fuel consumption
The U.S. government on April 1 issued the first national automobile fuel consumption and emissions of the new standard: 2012 to 2016, all U.S. cars and light trucks produced must meet a gallon (about 0.22 gallons 1 liter) gasoline driving 35.5 miles (about 1.6 km 1 mile), the average fuel economy standards, higher than the current standard of 25 miles per gallon increased by 42%. Over the same period, the average emissions per vehicle from 2012 down to 295 grams per mile in 2016 to 250 grams.
This is the United States since the 70s of last century from the first large-scale increase in fuel consumption standards and Obama is set by the Government in 2020 U.S. greenhouse gas emissions in 2005 decreased by 17% on the basis of part of the goal. Can the new climate bill passed in Congress this year are still skeptical about the case, the new standard is the White House to arrest global warming achieved important results.
U.S. Secretary of Transportation in the promulgation of standards Lahoud said the new standard is "historic", it encourages the development and application of new technologies for the automotive industry has set ambitious but achievable standard. "We want the United States is not only fuel-efficient cars, and environmental protection." According to the U.S. Environmental Protection Agency estimates that between 2012 to 2016 models sold in the United States will be able to save 18 million barrels of crude oil and reduce greenhouse gas emissions 960 million tons, equivalent to an annual reduction of 58 million cars on the road. The new standards may lead consumers to increase in the car when the cost per vehicle of about 1000 U.S. dollars, but consumers through fuel savings within 3 years can make up for this expenditure.
Over the years, the United States federal and state standards on car exhaust emissions vary. Among them, the State of California that the federal vehicle emission standards are too lenient, not conducive to controlling greenhouse gas emissions. The state in 2004 than the federal government issued a "Clean Air Act," provides a more stringent standard, and get the other 13 states and Washington DC response. Car manufacturers questioned the legitimacy of this standard, and the courts. The Bush administration supported the demands of car manufacturers to stop the implementation of California standards. January 2008, by the California led the U.S. 16 states sue EPA jointly to require states to allow the formulation vehicle exhaust emission standards.
Obama said after taking office, the federal government should cooperate with the states, rather than block states to reduce vehicle emissions on the efforts. May 2009, representatives of 11 U.S. and foreign automotive manufacturers in the United States the interests of the U.S. automobile industry alliances and state governments, labor and environmental organizations reach a settlement. This by the U.S. Department of Transportation and the Environmental Protection Agency jointly issued a new fuel consumption standards, is in May 2009 the U.S. government reached a settlement with the auto industry's product, as in recent years, U.S. auto makers, state and federal governments in the management of vehicle exhaust emissions on the differences and disputes arising from a stop.
The new standard, the U.S. car manufacturers that the new standards While harsh, but the next few years, vehicle fuel efficiency to set a clear road map. Vice Chairman of the U.S. automobile industry, Ms. Bergquist said that government policy has a more forward-looking, as soon as possible to develop the next phase of the new fuel consumption standards, the U.S. auto industry, more targeted research and development.
