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.

A synopsis of key findings from previous ICCT studies relevant to a 2025–2030 standard in the EU, including technology potential and associated compliance cost, the role of electrified vehicles, and the switch to a new emissions testing procedure.

Addresses several common misconceptions about light-duty vehicle fuel efficiency and greenhouse gas standards and focuses on Australia’s proposed light-vehicle CO2 standards and the effects they may or may not have on Australian motorists.

Finds that for cars, the cost for meeting a 2025 target value of 70 g/km (as measured in the New European Driving Cycle - NEDC) is between 250 and 500 euros higher than would be the case in a footprint-based CO2 target system.

Reveals that the efforts made by multiple Transport Task Group (TTG) countries to promote and support policies and programs—including stringent tailpipe emissions standards, fuel economy standards, low sulfur fuels, and green freight programs—are in good alignment with the long-term perspective and pathways of the Transport Task Group defined in the G20 Energy Efficiency Leading Programme.
