Mexico to have tougher truck emissions rule in 2020

A significantly tougher rule governing heavy-duty truck emissions in Mexico will take effect in 2020, earlier than the truck industry had wanted, a top government official said on Friday,

After years of heated debate between truck makers and environmental activists, new heavy-duty vehicles will have to meet emission standards used by the United States and the European Union, known as Euro VI, in 2020, Mexico's undersecretary for Environmental Policy and Planning, Rodolfo Lacy Tamayo, said in an interview.

New heavy-duty trucks will have to meet a lower emissions standard known as Euro V from July 1 . . .
