SwRI wins $20M EPA contract for emissions and fuel consumption testing, analytical services

Green Car Congress

When a vehicle is tested for emissions and fuel economy on a chassis dynamometer, the load from aerodynamic drag, friction, and tire losses associated with road operation must be simulated. First, actual on-road operation must be characterized, which is referred to as the road-load force specification.

Researchers Propose New Method for Life Cycle Impact Assessment; Transportation Fuels as a Case Study

Green Car Congress

Argonne’s GREET model (Greenhouse gas Regulated Emissions and Energy Use in Transportation) is, for example, an inventory tool. However, current normalization practices risk masking impacts that may be significant within the context of the decision, albeit small relative to the reference data (e.g., total US emissions).
