With technical supports from National Renewable Energy Laboratory (NREL) and World Resource Institute (WRI), USA, this case study was conducted to estimate the response towards expanding the use of natural gas as an alternative for SO2 emission reduction and health benefit in Shanghai.

The Emission-Air Quality-Health (MARKAL-TRANSMATRIX-HEALTH) model was used in the case study. The Market Allocation (MARKAL) model was used to estimate local air pollutant emissions. It is consisted of 22 energy carriers, 30 materials, 28 processes and 173 technologies, of which 21 are conversion technologies. The processes represent all activities necessary to provide products and services, many of which can be generated through a number of alternative processes based on different technologies.
