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.
Discusses the use of computer simulation to certify whole-vehicle efficiency of HDVs, and compares tools used to quantify HDV CO2 emissions in the US (GEM v2.0) and EU (VECTO v2.0.3 beta; not yet used in a regulatory context).
Evaluation, based on leading technology effectiveness, technology cost, and fuel price data, of payback periods for the efficiency technologies analyzed in a companion paper on tractor-trailer technology potential.
Evaluates eight vehicle replacement programs from around the world and identifies five best practices in the areas of program design and implementation, as well as fiscal incentives and policies, to serve as guidelines for policymakers.
Explores performance levels and adoption rates of trailer technologies that reduce fuel consumption in tractor-trailers and identifies challenges and opportunities going forward by capturing a broad cross-section of experts in the Canadian trucking industry.
