Compares official laboratory-test and on-road nitrogen oxide (NOx) emissions for 541 Euro 5 and Euro 6 diesel passenger cars, representing 145 of the most popular European models.

2017.08.31

Evaluates well-to-wheel greenhouse gas emissions from soot-free urban transit bus types in 20 megacities.

2017.08.29

A report investigating the real-world emissions of four Euro 6 passenger cars—one gasoline and three diesel vehicles with different aftertreatment technologies, tested under variable conditions. The investigation was conducted by the Laboratory of Applied Thermodynamics, of the Aristotle University of Thessaloniki, and its spin-off company, Emisia.

2017.08.24

Assesses the indirect greenhouse gas emissions of diverting waste and residual materials to biofuel production.

2017.08.23

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.

2017.08.15

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.

2017.08.09

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). The authors conclude that early adoption (in mid-2018) of the China 6b standard will help Guangdong address its most prominent air quality and human health concerns cost-effectively, in both the short and long term.

2017.08.01

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.

2017.07.28

Outlines the current procedure for the determination of fuel consumption, carbon dioxide (CO2) emissions, electric energy consumption, and electric range, specifically for PHEVs in Europe, highlights the most relevant changes expected with the introduction of the new Worldwide Harmonized Light Vehicles Test Procedure (WLTP) and discusses key differences between the EU and U.S. test procedures for PHEVs.

2017.07.27

A summary of the technology and policy landscape encompassed by the phrase "new mobility," and survey of considerations involved in ensuring that new mobility developments support and advance the goals of clean transportation.

2017.07.27

Examines the link between soybean and rapeseed biodiesel and palm oil in light of a new study on substitution effects.

2017.07.24

Assesses the U.S. electric vehicle market and the factors that are driving it. Catalogues electric vehicle promotion activities. Identifies best practice policies in the 50 most populous U.S. metropolitan areas. Conducts a statistical analysis to discern links between the promotion actions and electric vehicle uptake.

2017.07.20

Examines the HDV market in China and investigates the potential for currently sold vehicles to reduce fuel consumption through the adoption of known efficiency technologies. 

2017.07.16

Assesses, through vehicle simulation modeling, the baseline fuel efficiency performance and the potential of various fuel saving technologies to improve the efficiency of European tractor-trailers and rigid trucks, in the 2020–2030 timeframe.

2017.07.13

Evaluates the European Commission’s version of the proposed EU new motor vehicle type-approval framework, where it relates to market surveillance activities, and proposes specific ways in which it could be strengthened.

2017.07.10

Highlights important innovations and trends in diesel engines and emission control systems, some of which were not considered when the 2025 CAFE and greenhouse gas standards were finalized, yet promise to improve diesel passenger vehicles’ cost-effectiveness, especially for larger classes.

2017.07.10

Diesel engines, aftertreatment, and emissions control have developed since 2012, improving diesel vehicles’ cost-effectiveness, particularly for larger passenger vehicle classes.

2017.07.07

Summarizes the key barriers that impede the adoption of fuel-saving technologies in the trucking sector and discusses some of the ways policymakers can combat them.

2017.07.05

Despite the anticipated decline in diesel car sales future carbon dioxide (CO2) standards in the EU can still be met even if new-car diesel share falls as low as 15% by 2025. The net compliance cost for reaching a 70 g/km (NEDC) target by 2025 would decline by €10–€280 per vehicle, if the diesel market share were to drop to a level as low as 15%.

2017.06.30

Summarizes and analyzes preliminary data for 2016 recently released by the European Environment Agency (EEA) on CO2 emissions from new passenger cars in the EU. New cars sold in the EU in 2015 had average CO2 emissions of 118 g CO2/km, which was 1.2% lower than in 2015.
