During his first term, President Obama also put in place the first national policy to increase the fuel economy of medium- and heavy-duty trucks with model years between 2014 and 2018.
Tuesday’s regulations mandate that heavy-duty pickup trucks and vans must become 2.5 percent more efficient each year between 2021 and 2027.
Regulators will require other vehicles, such as tractor-trailers, deliver trucks and school buses, to have 25 percent lower carbon emissions and fuel consumption compared to existing standards. Diesel engines also will have to become more efficient.
And for the first time, the EPA is including efficiency standards for trailers as well--excluding some categories, including mobile homes--starting in 2018.
