Enter Phase 2

摘要

Announced in late summer after almost a year of comments and deliberations by scientists, engineers, and regulation writers at two federal agencies, the Phase 2 Greenhouse Gas and Fuel Economy rules will affect engine and truck design starting in model-year 2018 and running into 2027. The Environmental Protection Agency, which regulates exhaust emissions, and National Highway Traffic Safety Administration, which decrees how new vehicles should perform, said Phase 2 will cut emissions through reducing fuel consumption by 24 percent by 2027-a win-win proposition for both the environment and truck operators.
