GHG standards for light-duty vehicles: U.S. automaker performance report

National Program consisting of standards for light-duty vehicles that reduce greenhouse gas (GHG) emissions and improve fuel economy was established by U.S. EPA  and requires compliance with progressively more stringent GHG emission standards for the 2012 through 2025 model years. According to the annual GHG Performance Report, which formally documents the status of auto company compliance with the GHG standards, the auto industry outperformed the GHG standard by a substantial margin for the fourth consecutive year.
In particular, in model year 2015  overall industry performance was 7 g/mi of GHG emissions better than required by the emissions standard. Nine of the twelve manufacturers with sales greater than 150,000 vehicles reported meeting or beating their standard, with margins of compliance ranging from 23 g/mi (Nissan and Subaru) to exactly meeting their standard with no margin (BMW). Three manufacturers (FCA, Mercedes, and Kia) missed their unique 2015 standards by 3, 11, and 12  g/mi.  Read more at
