Starting January 1, 2021, all new HDVs sold in Mexico will be required to meet the best-in-class, filter-based standards, equivalent to those currently in place in the rest of North America and the European Union. The Euro VI and US 2010 options are introduced in 2019, along with much weaker Euro V and US 2007 options, which are allowed over a two-year transition period. The soot-free standards become the only regulatory option on January 1, 2021.

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.

Collects and analyzes real-world emissions data from multiple sources in China. The data include emissions of NOx, CO, and total hydrocarbons. from 55 LDVs and 67 HDVs tested using PEMS. The vehicle sample covers a wide range of emissions standards, from China 0 to China 5/V, and vehicle types.

Reviews recent research regarding greenhouse gas emissions from the manufacturing of lithium-ion batteries for electric vehicles. We analyze this research in the overall context of life-cycle emissions of electric cars as compared to conventional internal combustion vehicles in Europe. Finally, we discuss the primary drivers of battery manufacturing emissions and how these emissions could be further mitigated in the future.

Finds that ILUC emissions from energy cropping are highly sensitive to assumptions of the composition of marginal lands and suggests that additional sustainability safeguards may be necessary for energy cropping in order to ensure that it only occurs on low-carbon stock land.

2018.02.05

Explores some of the compliance pathways available to heavy duty vehicle manufacturers. Specifically, this paper develops hypothetical technology packages for certain types of tractor trucks, vocational vehicles, and trailers using distinct technology strategies compares cost-effectiveness.

2018.02.01

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.

2018.01.17

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.

2018.01.16

Summarizes the potential in Europe of presently available efficiency technologies to produce fuel savings that greatly exceed the upfront costs of technology and maintenance, and evaluates emerging advanced efficiency technologies that offer even more substantial fuel savings and short payback periods over the long term.

2018.01.16

Compares the fuel efficiency of 20 airlines operating nonstop flights between the mainland United States and East Asia and Oceania and extends the previous transatlantic fuel efficiency methodology to the transpacific market.

2018.01.11

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.

2018.01.09

Summarizes and evaluates key elements of the November 2017 European Commission proposal as it goes to the European Parliament and the European Council.

2018.01.03

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. 

2017.12.27

Comparison of the fuel efficiency of airlines serving 10 transborder routes between Canada and the United State for the 12 months between March 2016 and February 2017. 

2017.12.15

An updated global inventory of black carbon emissions from the global shipping sector with several recommendations on how to reduce black carbon emissions from ships.

2017.12.15

Assesses the environmental impacts of crop residue management to inform advanced biofuel policy in Europe.

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.

2017.12.14

A sharp increase in revenue passenger miles drove both profits and fuel consumption on domestic operations up between 2014 and 2016 for U.S. airlines. Alaska Airlines again ranked first in overall fuel-efficiency, while the gap between it and the least fuel-efficient carrier, Virgin America in 2016, widened slightly to 26%.
