In 2014, the G20 Energy Efficiency Action Plan prioritized the establishment of a Transport Task Group (TTG) to promote cooperation among participating G20 countries to develop domestic policies that improve the energy efficiency and environmental performance of motor vehicles, particularly heavy-duty vehicles.

This briefing paper identifies key differences in the regulations governing certification of NOX emissions from diesel cars (Euro 6) and trucks (Euro VI) that help explain

Annual statistical portrait of technologies, fuel consumption, and GHG and pollutant emissions in Europe's passenger car, light-commercial, and heavy-duty fleets.

Policy and public awareness related to truck pollution will have to be enhanced significantly to accelerate action and protect public health. Trucks are the deadliest source of toxic emissions and fuel guzzling.

The European Commission is preparing to extend the European Union's CO2 emissions regulation for passenger cars and light-commercial vehicles out to 2025–2030.

The European Commission has proposed the world’s toughest emission standards for non-road mobile machinery (NRMM), which will tighten restrictions and set stricter limits on emissions of particulate matter (PM). The Stage V emission standards will phase in as early as 2018 for approval of new engine types, and in 2019 for all sales.
