2017.12.14

The modifications required by US regulators to VW diesel engines designed to cheat emissions tests are more stringent and more effective than in Europe.

2017.11.28

A statistical portrait of passenger car, light commercial, and heavy-duty vehicle fleets in the European Union from 2001 to 2016, with emphasis on vehicle technologies, fuel consumption, and emissions of greenhouse gases and other air pollutants.

2017.11.05

This update adds one new data source, for a total of 14, covering 16 years, eight countries, and approximately 1.1 million cars. The analysis shows that, in the EU, the gap between official and real-world CO2 emission values continues to grow—from 9% in 2001 to 42% in 2016.

2017.11.05

Investigates the gap between real-world and official CO2 emission values in the four largest vehicle markets in the world: China, the EU, Japan, and the United States. The analysis shows that the gap has increased in all markets since 2001. 

2017.10.26

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.

2017.10.12

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.

2017.10.10

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.

2017.09.19

Summarizes provisions of the first national-level remote sensing regulation adopted by China for diesel vehicles.

2017.09.05

Legal brief summarizing public access to vehicle emissions data in the EU and US.

2017.09.03

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.

2017.08.29

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.

2017.08.15

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.

2017.07.28

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.

2017.07.13

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.

2017.06.30

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.

2017.06.26

Results of a project by the International Centre of Automotive Technology (ICAT), in India, to conduct laboratory and on-road testing of three in-use vehicles, using a portable emissions measurement system, over a variety of drive cycles and routes.
