Project at a Glance

Project Status: active

Title: Measuring real-world emissions from the on-road passenger car fleet

Principal Investigator / Author(s): Stedman, Donald and Gary Bishop

Contractor: University of Denver

Contract Number: 12-303

Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels

Research Summary:

The study will yield light-duty exhaust emission trends and distributions by vehicle model year and age, and explore the feasibility of measuring running loss evaporative emissions using RSDs. The results will be used to evaluate the effectiveness of Californiaís LEV II program in reducing vehicle exhaust emissions, and to investigate a potential new method to identify gross evaporative emitters.
