DEVELOPING A FIRST-EVER NATIONAL MOBILE SOURCE EMISSIONS INVENTORY FOR CHINA

Abstract:

The Chinese Ministry of Environmental Protection (MEP) recently initiated a first-ever national pollution source census to be completed in 2009. The Vehicle Emission Control Center of MEP (VECC-MEP), is responsible for the mobile source emissions component of the pollution census. VECC-MEP has undertaken the project in three stages. The first stage, data collection, was completed over the fall and winter of 2007-2008, and entailed the detailed surveying of vehicle population and activity data in 345 cities in China. The second stage, emission factor model development, is currently underway, with an expected completion date of December, 2008. VECC-MEP is surveying existing emission factor models, including COPERT, MOBILE, the IVE model, and more, to determine the most appropriate structure and methodology for a China-specific model. Key considerations include Chinese data availability and reliability as well as how to model China's unique populations of 2 and 3-wheelers and heavy duty vehicles. The third and final stage of the project, completion of the total inventory, will be undertaken during winter and spring of 2008-2009. In this presentation, we introduce the first and second stages of the project, describing key accomplishments of data collection and model development as well as remaining challenges.
