Abstract

CO2 and SO2, while having different environmental impacts, are both linked to the burning of fossil fuels. Research on joint patterns of CO2 emissions and SO2 emissions may provide useful information for decision-makers to reduce these emissions effectively. This study analyzes both CO2 emissions and SO2 emissions embodied in interprovincial trade in 2007 and 2010 using multi-regional input–output analysis. Backward and forward linkage analysis shows that Production and Supply of Electric Power and Steam, Non-metal Mineral Products, and Metal Smelting and Pressing are key sectors for mitigating SO2 and CO2 emissions along the national supply chain. The total SO2 emissions and CO2 emissions of these sectors accounted for 81% and 76% of the total national SO2 emissions and CO2 emissions, respectively.

Highlights

  • The Paris Agreement entered into force on 4 November 2016 signed by 188 countries, accounting for over 90% of global greenhouse emissions [1,2]

  • In order to provide more information for provincial government to formulate and implement environment-friendly measures and climate policies, we investigated both CO2 emissions and SO2 emissions embodied in interprovincial trade inside China using multi-region input–output (MRIO) analysis, backward and forward linkage were used to help identify sectors and regions to prioritize emission-reduction measures

  • There are two methods of calculating carbon emissions embodied in trade: the emissions embodied in bilateral trade (EEBT) framework and multi-regional input–output analysis (MRIO)

Summary

Introduction

The Paris Agreement entered into force on 4 November 2016 signed by 188 countries, accounting for over 90% of global greenhouse emissions [1,2]. One of the persistent problems of controlling carbon emissions is that China’s energy structure is still coal-dominated the economy is being restructured (National Bureau of Statistics of China, 2016). Linked to this structural problem is the serious haze pollution that is afflicting many areas in China. China should combine air-quality improvement with carbon emission reduction targets, through better coordination between departments and joint emission control measures, since connecting CO2 emissions mitigation with air-quality management measures is more effective. In order to provide more information for provincial government to formulate and implement environment-friendly measures and climate policies, we investigated both CO2 emissions and SO2 emissions embodied in interprovincial trade inside China using multi-region input–output (MRIO) analysis, backward and forward linkage were used to help identify sectors and regions to prioritize emission-reduction measures
