The US government Thursday finalised new automobile fuel economy standards starting with 2012 models, a move officials said would save billions of barrels of oil and reduce greenhouse emissions. The rules announced by the Department of Transportation and Environmental Protection Agency "will significantly increase the fuel economy of all new passenger cars and light trucks sold in the United States," the agencies said.
"The rules could potentially save the average buyer of a 2016 model year car 3,000 dollars over the life of the vehicle and, nationally, will conserve about 1.8 billion barrels of oil and reduce nearly a billion tons of greenhouse gas emissions over the lives of the vehicles covered."
Starting with 2012 model year vehicles, the rules require automakers to improve fleet-wide fuel economy and reduce fleet-wide greenhouse gas emissions by roughly five percent every year. By 2016 the industrywide standard will be 34.1 miles (54.9 kilometers) per gallon (3.8 liters), taking into account improvements in efficiency of car air conditions.
The standards also require that by the 2016 model-year, manufacturers must achieve a combined average vehicle emission level of 250 grams of carbon dioxide per mile. "We will be helping American motorists save money at the pump, while putting less pollution in the air." DOT and EPA received more than 130,000 public comments on the September 2009 proposed rules before issuing the final standards.
