Federal Agencies Releases Phase 2 Truck Emissions Rule

August 16, 2016 - The Environment Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) issued the Phase 2 Truck Emissions Rule.  This rule sets new fuel economy and greenhouse gas emissions (GHG) standards for heavy-duty trucks for model years 2021 through 2027.The Phase 2 program will include technology-advancing standards that will reduce GHG emissions and fuel consumption. The Agencies outlined the following program highlights:

  • Achieves 10 percent more GHG reductions.
  • Has more robust compliance provisions such as more repeatable and accurate test procedures, enhanced enforcement audits, and protection against defective devices.
  • Includes more stringent diesel engine standards, and an improved vocational vehicle program with a regulatory structure that is better tailored to match the right technology for the job.
  • Maintains the structure and incremental phase-in of the earlier proposed standards, allowing manufacturers to choose their own technology mix and giving them the lead time needed to ensure those technologies are reliable and durable.
  • Increases flexibility to minimize impacts on small businesses. 

TIA, along with other industry stakeholders, supports lowering greenhouse gas emissions, improving air quality, and making roads safer.  However, federal agencies continue to propose rules that raise the bar in those areas to levels that cannot be supported based upon engineering costs and market concerns.
