Analyzes the model structure, simulation flow, and limitations of the EU’s regulatory tool for the simulation of heavy-duty vehicle fuel consumption. Compares the regulatory vehicle simulation tools used in the EU and the United States.
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.
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.
Annual update to ICCT's ranking of U.S. airlines by fuel efficiency on domestic operations. The gap between most- and least-efficient airlines narrowed slightly to 25%, and overall industry fuel efficiency improved by 1.7%.
This annual update to the L2R series analyzes eleven data sources covering fourteen years, six countries, and almost 600,000 vehicles. In the EU the gap between official and real-world vehicle CO2 emissions grew to 38 percent in 2014.
Analyzes results of emissions tests on 32 Euro 6 diesel passenger cars from 10 different manufacturers. Results show some automakers meeting diesel NOx emissions standards under more realistic driving conditions, while others lag badly.
Inspection and maintenance (I/M) programs are key to identifying high-emitting vehicles and mitigating their impact on air quality and climate. This paper assesses best practices for I/M programs targeting heavy-duty vehicles and makes recommendations on how to improve HDV I/M programs in the future.
Analyzes the implications of a growing natural gas vehicle fleet on the emission benefits of the U.S. HDV “Phase 2” greenhouse gas rulemaking, synthesizing data on upstream emissions, vehicle emissions, and efficiency technology.
Surveys actions being taken by state and local governments and public utilities to facilitate electric vehicle deployment in the 25 largest U.S. metro areas. Presents city-specific analysis of consumer benefits and links between policies aimed at promoting EVs and market uptake.
