“…However, the utilization efficiency of coal is relatively low. The lack of energy efficiency in existing coal-fired power plants and coal-fired industrial boilers has resulted in large amounts of waste and pollutant emissions [46,47]. To quickly achieve energy savings and emission reduction, actively promoting and implementing the clean and efficient use of coal to increase energy efficiency is necessary.…”

Due to the large-scale utilization of high-carbon fossil energy, considerable amounts of critical air pollutants (CAPs) and greenhouse gas (GHG) have been emitted, which has led to increasingly serious global climate change and local air pollution problems. Given that climate change and air pollution have the same source, energy systems, the rational development and use of energy for collaborative governance should be emphasized to solve these problems in parallel. This paper presents a multi-dimensional, multi-perspective and achievable analysis framework to quantitatively evaluate the emission reduction effects of energy countermeasures aimed at tackling climate change and governing air pollution in support of sustainable development. As a typical developing country pursuing sustainable development, China is taken as an example to demonstrate an application of the proposed framework to assess the emission reduction effects of energy countermeasures issued for tackling climate change and governing air pollution on CAPs and GHG. The results indicate that the key energy actions proposed in this paper would result in emission reductions of approximately 6 million tons (Mt) of CAPs and 575 Mt of GHG in 2016. By 2020 and 2030, emission reductions of 12 Mt of CAPs and 1094 Mt of GHG and of 21 Mt of CAPs and 1975 Mt of GHG, respectively, will be achieved. The proposed framework can effectively help China identify the emissions reduction effect of a given energy countermeasure and support the development of policy describing the next steps for tackling climate change and haze pollution. The proposed framework in this paper is also beneficial for countries similar to China in their efforts to simultaneously address climate change and improve air quality.

“…China has been the world's top producer and consumer in key industrial products such as steel, cement, aluminum, paper and chemicals, which are primarily driven by the demand of downstream industries (e.g. construction, automotive and packaging sectors) (Liu et al, 2016). The industrial sector has been a major driver of China's economic boom, and is thus responsible for the vast majority of total energy demand.…”

“…Dependent on the perspectives, various discount rates are used to estimate the economic benefi ts of energy effi ciency improvement and emission reduction (Hasanbeigi et al, 2013). From the perspectives of policy making and market investment, discount rates of 4 % to 30% are used to assess the sensitivity of cost-eff ective potentials in diff erent grids (Wang et al, 2016). Table 3.7 and Figure 3.18 show the eff ect of various discount rates on the economic potentials of electricity saving and associated emission reduction at a grid level (while other parameters remain constant).…”

“…Karali et al (2017) used the industry sector energy effi ciency model (ISEEM) to evaluate the impacts of 24 energy effi ciency measures on energy-savings and CO 2 emission reduction in U.S. iron & steel industry between 2010 and 2050, and indicated 180 PJ energy use and 14.9 billion tons of CO 2 emissions would be saved by 2050. Unlike the single-product industries (iron & steel, cement and power (Wang et al, 2016)), few studies have separately estimated the potentials of CO 2 emission mitigation and energy conservation in the chemical industry Saygin et al, 2011;Lin and Long, 2015). studied the CO 2 emissions though emission factor-based methods and two-level method from the whole chemical industry and sub chemical sectors level respectively, and suggested large amounts of CO 2 can be saved in China's chemical industry.…”
