“…In 2015, the GDP of the two study regions accounted for 29% of the national GDP [21]. In the same year, the energy demand accounted for 27% of the national energy demand, according to [22]. Also, the specific energy consumption per GDP in BTH is significantly higher than the national average of 1.3 MJ/RMB.…”

With an expected accelerated urbanization process until 2050, China is facing big challenges of mitigating CO2 emissions, especially in the eastern coastal metropolitan regions. Since cities are the hubs for innovation regarding new technologies and infrastructures, investments and governance, they are playing an important role in decision-making and implementation processes on the way to a decarbonized economy and society. The national and provincial administrations in China have already started to address the issue of energy system transition toward a low-carbon pathway, but long-term integrated transition plans are not yet available on a regional level. In our paper, we therefore consider the main challenges of the energy system transition, such as efficiency improvement, coal reduction, decarbonization of transport, and multisector electrification with regional integration, focusing on two eastern coastal metropolitan regions of China. A systematic review of current near-term policies reveals how far these challenges have already been addressed on different administrative levels and which gaps may exist from an external perspective. Based on the current decision- and policy-making processes among national, regional, provincial and municipal levels, policy implications are identified with regard to an effective energy system transition in eastern China.

“…From a yearly perspective, apart from the interval time affected by economic activity, power generation efficiency is the suppressing driver in carbon emissions from the power industry. The change of thermal power generation efficiency can be attributed to two aspects: technology and management [7].…”

“…Without a doubt, carbon emissions from China's power industry is a major origin in China and throughout the world. Statistics show that in the past decade, the emission growth from China's power industry accounted for 49.1% of the country's total and 32.1% of the world's total [7]. After years of rapid increase, energy-related CO 2 in China's power sector has reached more than 3671.1 Mt.…”

As an important single source to carbon emissions, China's power industry should bear social responsibility for mitigating climate change. To explore what low-carbon development means for the industry, a novel approach that combines the extended multilevel LMDI model with Tapio algorithm was conducted to study the drivers of carbon emissions in the power industry and whether CO 2 emissions from power output is out of sync with economic development, covering the period from 1996 to 2016. Our results come to the following: 1. Carbon emissions from electricity output are characterized by increases and volatility, with an average annual growth rate of 7.05%. The carbon emission factor of electricity, facilitating to compute CO 2 data, shows a decline. 2. The positive driving factors are economic activity effect (169.53%), population scale effect (9.29%), fuel mix structure effect (0.41%), and electricity trade effect (1.05%); the negative driving factors are electricity intensity effect (-46.38%), power generation efficiency effect (-24.93%), and power generation structure effect (-8.97%). 3. Weak decoupling and expansive decoupling are the main status during the research period. The electricity intensity effect is the main force to promote the decoupling process. 4. The market-oriented reform in the power industry in 2003 has a significant effect. The generationside competition mechanism successfully changes the historical developmental trend of the decoupling elastic index.

Abstract:China is now facing great challenges resulting from climate change and air pollution, driven by the processes of industrialization and urbanization. Greenhouse gas and air pollutant emissions produced by the coal-fired power industry represent approximately 70% of the total emissions in China's industrial sector. In this study, 39 coal-fired power plants built in China between 2014 and 2015 were analyzed in regards to the co-effects oncarbon dioxide and air pollutant emissions generated directly and indirectly by end-of-pipe measures of pollution control. After completing the quantitative analysis with input data from 83units of power plants, we found that co-effects were positive only for air pollutant reductions through the implementation of desulfurization, denitrification, and dedusting measures, but co-effects were negative for carbon dioxide production because of the corresponding electricity use and chemical reactions that led to the increases in carbon dioxide emissions. We also performed an assessment of the synergistic coefficients to better understand the degree of co-effects. It will be important for researchers to take a comprehensive view of China's coal-fired power plants and look for solutions that can maximize positive co-effects and achieve overall co-benefits of reductions in greenhouse gas emissions and air pollutants.
