White House announces large truck emission regulations

Although never regulated before, the Obama administration has announced new emission standards for large trucks.

As expected, the Obama administration has announced its first round of fuel economy regulations for large trucks. The regulations, which were penned by the Environmental Protection Agency and National Highway Traffic Safety Administration, extend through 2018.

The White House's new regulations cover medium- and heavy-duty trucks - two segments that have never been subject to emission laws. Large trucks make up only 4 percent of the nation's road traffic, but generate 20 percent of road-going emissions.

The Obama administration's new regulations will require semi trucks to cut emissions by 20 percent by 2018. Diesel-powered heavy duty vans and trucks will need to emit 15 percent fewer tailpipe emissions while their gasoline counterparts will need to cut emissions by 10 percent. Buses, RVs and garbage trucks will be subject to the same 10 percent reduction.

President Obama is expected to have the regulations finalized by July 30th, with the new rules set to begin for the 2014 model year. The regulations will extend through 2018.
