This technical report supersedes previous reports and details manufacturers’ performance towards meeting GHG standards in the 2015 model year, the fourth year of the GHG standards which become increasingly stringent in each model year from 2012 through 2025. Shows that overall industry performance in model year 2015 was 7 g/mi better than required by the 2015 GHG emissions standard. This marks the fourth consecutive model year of industry outperforming the standards by a sizeablemargin .
In this mandated final review of the standards, the EPA determined to leave the standards in place, stating that they “are projected to reduce oil consumption by 50 billion gallons and to save U.S. consumers nearly $92 billion in fuel cost over the lifetime of MY2022-2025 vehicles”, with minimal employment impacts. President Trump re-opened that decision in March 2017.
This draft regulatory analysis document, at 377 pages, is complex and comprehensive, looking at multiple impacts. Chapter 8, which deals with employment effects of the new regulations, surveys multiple models and concludes with a highly qualified statement that "For the regulated sector, the cost effect is expected to increase employment by 600 - 3,600 workers in 2017, depending on the share of that employment that is in the auto manufacturing sector compared to the auto parts manufacturing sector."
