In the transportation sector, refers to regulation that directly limits carbon dioxide emissions from a vehicle, as opposed to restricting those emissions indirectly (through, e.g., fuel economy standards). Examples would include the U.S. EPA 2016 standards for light-duty vehicles, which require LDVs to meet an estimated combined average emissions level of 250g CO2 per mile, or the EU rules establishing fleet-average emissions targets of 95g CO2 per kilometer for passenger cars and 175g CO2 per kilometer for light commercial vehicles.
This paper compares fuel consumption / CO2 values of passenger cars from different sources and aims at quantifying the discrepancy between laboratory type-approval values and real-world values, including a retrospective analysis for the years 2001-2011 to determine if the gap between the two datasets has increased over time. Potential explanations for the discrepancies found are discussed and possible practical solutions for the future outlined.
