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.


Describes case studies of energy cropping in Europe in the context of advanced biofuel and bioproducts sustainability.
