Abstract For the past 20 years, sulfur dioxide (SO 2 ) emissions control has been a goal in China whose economy has been characterized as fast growing and in enormous transition. As a prerequisite for effective future SO 2 emissions control, a detailed investigation is needed to uncover and assess the contributions to changes in SO 2 emissions of key underlying drivers associated with China’s evolving demand structure. Using structural decomposition analysis (SDA), considering industrial characteristics and sector interactions, this study identifies the underlying drivers behind China’s demand structure shifts as well as their contributions to changes in industrial SO 2 emissions. The results show that the change in total final demand was the largest driver of the increase in SO 2 emissions, resulting in an increase of 36.64 million tons (Mt) SO 2 emissions during the time period 1997 to 2012. From the final demand perspective, the change in capital formation was the largest contributor, resulting in an increase of 16.78 Mt SO 2 emissions, and accounting for 45% of the increase due to final demand shifts. The construction industry was the primary trigger of industrial SO 2 emissions growth caused by shifts in final demand, with an induced amount (impact on other industries) of SO 2 emissions of 10.14 Mt. The key drivers capturing shifts in final demand were mainly capital formation in the construction industry, capital formation and exports in technology-intensive industries, and consumption in the services industries. The recommendation is that to control industrial SO 2 emissions, China should depend first on its economic transition that includes technology improvements and industry structure optimization for both final demand and production.
