Although some states in America already have very strict rules about fuel emission which cannot be passed by many cars with European standards, President Obama and his team have announced that they would set new rules to make the manufacturers produce more environmentally friendly cars.

The final Corporate Average Fuel Economy rules and regulations should be announced today. The good side of these regulations is that it will eliminate the great difference between the federal standards and extremely high standards in some states like California.

President Obama and his team plan to ask the auto manufacturers to start making cars and trucks with average 35.5 mpg usage by 2016: passenger cars should use 39 mpg and trucks – 30 mpg. While many think that the administration wants to make everybody drive little fuel-efficient cars, it has been noted that the size of the vehicles would not change, but the autos of all sizes will use less fuel.

The future will show how well the new requirements will be accepted, as for now Edmunds.com CEO Jeremy Anwyl says, “Defining what should be built does not create demand. There are tons of great fuel-efficient cars out there today but most consumers aren't interested, and the new fuel-economy standards don't appeal to deal with the demand side at all.”
