The new rules, introduced in the wake of the Volkswagen emissions scandal, will allow construction companies to make and install more efficient cars and buses.
The European Union is currently negotiating a deal with the US and other countries to ensure the vehicles will be built in the EU and will not be subject to US tariffs.
The rules, which were announced on Monday, will come into force in 2019, after the US administration had already given provisional approval to the new emissions standards.
The European Commission, which is responsible for implementing the regulations, said it will consult on the rules.
“We are committed to supporting the implementation of the new rules and to ensuring that the most sustainable use of resources is preserved,” EU commissioner for environment, environment and fisheries Cecilia Malmstrom said in a statement.
She said the regulations would also help protect the environment and boost investment.
“The Commission will work with the federal governments to ensure that the measures take account of the needs of both the EU’s economy and the environment,” Malmstroth added.
