The heavy-duty industry should monitor California developments -

Key Points:

..The Obama EPA initiated new rulemaking to further reduce NOx emissions from on-highway, heavy-duty diesel engines and vehicles.

..The Trump administration’s regulatory pullback, however, could prompt California action with nationwide consequences.

..Component makers, in addition to engine and vehicle manufacturers, must now keep abreast of California developments as recent rulemakings have increasingly vehicle-wide impacts but also offer opportunity for competitive advantage.
