Abstract
It is a very urgent issue to reduce energy-related carbon emissions in China. The three northeastern provinces (Heilongjiang (HLJ), Jilin (JL), and Liaoning (LN)) are typical heavy industrial regions in China, playing an important role in the national carbon emission reduction target. In this study, we analyzed the energy consumption, carbon dioxide (CO2) emissions, and CO2 emission intensity of each sector in the three regions, and we compared them with the national level and those of China’s most developed province Guangdong (GD). Then, based on an input–output (I–O) framework, linkage analysis of production and CO2 emission from sector–system and sector–sector dimensions was conducted. The results showed that the three regions accounted for about 1/10 of China’s energy consumption and 1/6 of China’s CO2 emissions in 2012. In addition, the level of energy structure, CO2 emission intensity, and sectoral structure lagged behind China’s average level, much lower than those for GD. According to the sectoral characteristics of each region and unified backward/forward linkages of production and CO2 emissions, we divided sectoral clusters into those whose development was to be encouraged and those whose development was to be restricted. The results of this paper could provide policy–makers with reference to exploring potential pathways toward energy-related carbon emission reduction in heavy industrial regions.
Highlights
Greenhouse gas (GHG) emissions led to a series of environmental problems including the greenhouse effect [1]
The CO2 emissions are calculated by the terminal energy consumption model proposed by the Intergovernmental Panel on Climate Change (IPCC) [33]
I–O tables (2012) of the three heavy industrial regions and 2012 terminal energy consumption data were used in this study
Summary
Greenhouse gas (GHG) emissions led to a series of environmental problems including the greenhouse effect [1]. As the main component of GHG, energy-related carbon emissions account for more than 80% of the world’s anthropogenic emissions [2]. From 1751 to 2012, China accounted for 10.7% of the world’s cumulative energy-related carbon dioxide (CO2 ) emissions. The State Council of China formulated three phases of policies on energy conservation and emission mitigation in the “five-year” cycle and made some achievements [4,5,6]. As the largest developing country, China is still facing great challenges in controlling energy consumption and CO2 emissions on the premise of ensuring stable economic development [7,8]
