In the aftermath of Dieselgate, diesel car sales shares are falling in Europe. But diesel's decline does not put EU CO2 targets out of reach. Other technologies offer more compelling and cost-effective pathways to reducing CO<sub>2</sub> emissions from passenger cars.
This case study shows that the actual CO2 reductions of 18.6% achieved in the 2018 Camry exceed the 17.7% reductions predicted by EPA models. This confirms that the OMEGA and LPM models accurately predict both new technology benefits and synergies between technologies. It also suggests that other studies contradicting EPA model outcomes are inaccurate and underpredict future technology benefits.
Effectively enforced vehicle CO2 performance standards are at the core of any effort to realize lower-carbon transport. EU member states should implement supporting policy measures such as emissions-based vehicle taxes, mandates for electric vehicles, and emissions-based road pricing.
A comprehensive overview of vehicle remote sensing, an emissions measurement technique which has been used for more than 25 years to evaluate emissions from passing motor vehicles in real-world driving. Reviews technical details of the vehicle remote sensing test method, describes the multiple types of emissions analyses that can be conducted with remote sensing data, and explores areas where remote sensing can supplement emission test methods currently used in the European Union light-duty vehicle regulatory program.
Der derzeitige Rückgangs des Dieselanteils zieht keine negativen Auswirkungen auf die Erreichbarkeit der Klimaschutzziele nach sich. Vor diesem Hintergrund sollte ein Festhalten an der derzeitigen Subvention von Dieselkraftstoff für Pkw kritisch hinterfragt und eine Angleichung der Steuersätze für Diesel und Benzin in Erwägung gezogen werden.
A transparent assessment of the current new passenger vehicle market in South Africa in terms of CO2 emissions, and provides an evaluation of the benefits of adopting fuel economy and CO2 emission standards in those vehicles.
Provides an overview of how the NEV mandate will work, summarizes major differences between the interim proposal and the final rule, and evaluates potential impacts.
Summarizes and evaluates key elements of the November 2017 European Commission proposal as it goes to the European Parliament and the European Council.
Investigated the impacts of updating three standards in Mexico to align with the international best practices employed in the rest of North America: gasoline and diesel sulfur standards, passenger vehicle emissions standards, and truck and bus emissions standards.
The modifications required by US regulators to VW diesel engines designed to cheat emissions tests are more stringent and more effective than in Europe.
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.
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.
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.
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.
Summarizes provisions of the first national-level remote sensing regulation adopted by China for diesel vehicles.
Legal brief summarizing public access to vehicle emissions data in the EU and US.
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.
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.
