On Friday, the Obama administration officially announced plans to further lower carbon emissions in the United States. This new rule, issued by the Environmental Protection Agency (EPA) and the Transportation Department, aims to increase the fuel efficiency of the large trucks crossing the country everyday. New regulations will also affect other trucks, such as delivery vehicles, dump trucks and buses.
Two categories of standards were created, one for the front part of big trucks, called tractors, and one for trailers that trucks haul. The tractor standard will be implemented for those built in 2021 and require efficiency increases of up to 24 percent. This will be the first time, however, that regulations extend to trailers. The first federal standards for big trucks were announced in 2011 for any truck models built between 2014 and 2018.
