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.

This briefing provides a synthesis of information regarding the global development of hydrogen fueling infrastructure to power fuel cell vehicles. The compilation includes research on hydrogen infrastructure deployment, fuel pathways, and planning based on developments in the prominent fuel cell vehicle growth markets around the world.

Assesses zero-emission heavy-duty vehicle technologies to support decarbonization of the freight sector in the 2025–2030 timeframe. Synthesizes data from the research literature, demonstrations, and low-volume commercial trucks regarding their potential to deliver freight with zero tailpipe emissions.

An analysis of advanced biofuel policies and recommendations for improving the effectiveness of policy support for emerging low carbon fuel technologies.

Analyzes the benefits of establishing separate engine CO2 standards in addition to full-vehicle regulations to specifically drive improvements in heavy-duty engine efficiency.

Urban transit bus fleets are a significant source of air pollutant emissions, including black carbon, a harmful ultrafine particle and potent short-lived climate pollutant. Transit bus fleets are therefore an important target for accelerated transitions to clean engine technologies and fuels.

Compiles a high-resolution ship emissions inventory in the Greater Pearl River Delta (GPRD), a heavily populated and prosperous region with heavy ship traffic. Because this traffic contributes to poor local air quality, the Chinese government has identified the GPRD region as a key target for steps to control emissions from ships.

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

Reviews the costs and benefits that would result from implementing the China 6 light-duty vehicle emission standard in Guangdong Province with a recommended timeline earlier than the national plan (2023).

Summarizes provisions of the implementing act adopted in May 2017 by the European Union for type-approval of CO2 emissions and fuel consumption of on-road heavy-duty vehicles, which will go into effect in 2019 and 2020.
