Carbon Mitigation Pathway Evaluation and Environmental Benefit Analysis of Mitigation Technologies in China’s Petrochemical and Chemical Industry

Abstract

The co-benefits of mitigation technology in China’s petrochemical and chemical industry have not been evaluated, although they are deemed valuable for the cost-benefit analysis of carbon mitigation. On this basis, this study evaluates the carbon mitigation effects and environmental co-benefits of mitigation technologies that have been long ignored in China’s petrochemical and chemical industry. In addition, this study also fills the gap of provincial research in chemical industry. A bottom-up energy model and marginal abatement cost curves are constructed for each sector. The study is based on national and provincial levels to provide quantitative reference for the mitigation technologies. Results show that, among 18 technologies in the chemical industry, waste heat utilization and technological process transformation technologies have the highest marginal abatement benefits. Technologies in the petrochemical industry with the largest marginal abatement social benefit typically exists in three categories: efficiency improvement technology, waste heat utilization technology, and coating technology. At the national level, 8039 and 5105 premature deaths are effectively avoided by the promotion of chemical and petrochemical mitigation technologies, respectively. Monetary value of health impact in these two industries are 7.0 billion and 5.5 billion RMB, respectively. At the provincial level, coal gasification multi-generation gas turbine power generation technology, a technological process transformation technology, performs well in Shaanxi province with 122 million RMB of total social benefit.
