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.

This case study shows that the actual CO2 reductions of 18.6% achieved in the 2018 Camry exceed the 17.7% reductions predicted by EPA models. This confirms that the OMEGA and LPM models accurately predict both new technology benefits and synergies between technologies. It also suggests that other studies contradicting EPA model outcomes are inaccurate and underpredict future technology benefits.

Effectively enforced vehicle CO2 performance standards are at the core of any effort to realize lower-carbon transport. EU member states should implement supporting policy measures such as emissions-based vehicle taxes, mandates for electric vehicles, and emissions-based road pricing.

A transparent assessment of the current new passenger vehicle market in South Africa in terms of CO2 emissions, and provides an evaluation of the benefits of adopting fuel economy and CO2 emission standards in those vehicles.
