Medium- and heavy-duty trucks, ranging from school buses to dump trucks, will have to meet tightened greenhouse gas emissions standards and fuel economy standards released today by the Obama administration.
The Environmental Protection Agency and the National Highway Traffic Safety Administration jointly finalized the regulations to be phased in through 2027, which the Obama administration estimates will save 1.1 billion metric tons of carbon dioxide emissions and generate $230 billion in net benefits over the life of the program.
"We expect this will drive innovation as well as protect the air that we breathe," EPA Administrator Gina McCarthy told reporters, calling one of the final landmark regulations expected to be issued under the Obama administration "ambitious and achievable."
Secretary of Transportation Anthony Foxx said the final rule will result in approximately 10 percent more greenhouse gas reductions than the proposal.
The final action did not decide on whether to tighten nitrogen oxide emissions limits sought by a coalition of public health organizations, though McCarthy noted "there is a need to move forward" with additional reductions there.
