Topics / CO2 standards

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.
