Big rigs and other heavy vehicles will have to cut their carbon emissions and fuel consumption 25 percent from current models under new rules announced Tuesday by the Obama administration.
The rules are the last in a suite of regulations that have been issued under President Obama’s climate change agenda.
The tractors used in tractor-trailer vehicles, delivery trucks, school buses and other vocational vehicles by 2027 are expected to cut greenhouse gas emissions emissions by 1.1 billion tons and reduce oil consumption by 84 billion gallons, compared to the first round of standards that expire in 2018. The Environmental Protection Agency, the U.S. Department of Transportation and the California Air Resource Board jointly announced the regulations.
In addition, heavy-duty pick up trucks and vans must become 2.5 percent more efficient annually between model years 2021 and 2027.
EPA Administrator Gina McCarthy called the new standards “ambitious and achievable,” and said it’s up to the automobile sector to develop new technologies to meet the standards.
“We expect these will drive innovation as well as protect the air we breathe,” she said.
The government did not immediately release the expected costs of the standards, but said the expected $170 billion in fuel cost savings would more than outstrip the costs.
