Poor air quality has extremely detrimental health consequences, including cancer, stroke, asthma or heart disease. Existing research on air pollution-induced environmental injustice (EI) in Hong Kong (HK) is based on sparse air pollution data due to the limited number of pollution monitoring stations, rendering the study of the relationship between air pollution exposure and social deprivation (SD), and the subsequent study of EI at finer geographical scales difficult. A key research question remains to be explored in a methodologically rigorous manner: Are the socially deprived exposed to a higher level of PM 2.5 pollution in HK? Our study develops a Granger Causality model, utilizing ubiquitous urban dynamics closely related with air pollution, including ambient pollutants concentration, traffic, meteorology and urban morphology to provide a fine-grained estimation of air pollution in HK at 100 m × 100 m spatial resolution, achieving a 82% accuracy. We focus specifically on ambient PM 2.5 concentration, given its serious health consequences and the preliminary evidence of differential PM 2.5 distribution across different socio-economic groups in HK. We investigate if there is any differential distribution in PM 2.5 pollution across people residing in constituency areas (CAs) with different levels of SD. In our study, SD is measured by the Social Deprivation Index (SDI), which is a composite indicator comprising four socio-economic status variables, namely, low-income, low-education, non-professional occupation, and non-owner occupier, selected and combined via principal component analysis. We conclude there is a statistically significant, positive relationship between ambient PM 2.5 concentration and SDI in HK, based on the SDI and mean PM 2.5 exposure values derived from 412 CAs (R 2 = 1.4%, p -value <0.01, based on ordinary least squares), justifying the existence of PM 2.5 -induced SD and EI at the CA level in HK. Our study highlights an emerging need for HK to develop more integrated, human-centric, location- and justice-based environmental policies, and the need to adopt evidence-based policy-decision-making to properly address air pollution-induced EI. Our policy implications and recommendations can be extended to the rest of the world, particularly the Asian metropolis, as well as places where GDP growth is rapid, population density and pollution concentration (including particulate pollution) appear to be high, and the income gap between the rich and the poor is widening.

China has the world’s highest levels of carbon dioxide (CO 2 ) emissions, and its adoption of optimal measures to address climate change is extremely important. In this article, we assess the performance of various Chinese policies aimed at addressing climate change in terms of cost effectiveness, cost-benefit efficiency, and their contribution to a reduction in emissions with a new single-region model, DEMETER-CCPE. Our analysis shows that the performance of these Chinese policies strongly depends on the principles and indicators used in the evaluation. When climate-specific cost indicators are considered, the mixed policy performs best in terms of cost reduction. When cost-efficiency indicators are used, a single policy performs better to some extent. From the perspective of evaluating the contribution to emissions reduction, the development of non-fossil-fuel-based energy technologies offers the greatest opportunity for reducing emissions in a mixed-policy scenario. Finally, this article study possible ‘burden’ and ‘free-rider’ scenarios in order to explore the effect of different levels of joint actions between China and the rest of the world (ROW) on a performance evaluation of policies to address climate change.

In recent decades, China has been facing serious water pollution crises. To address this problem, discharge standards for wastewater treatment plants in China are becoming more and more stringent. Also, the sewage charge for compliant emissions and the penalty rate for non–compliant emissions have increased significantly. This paper comprehensively investigates the economic and environmental implications of such wastewater management policy in China. In this paper, a general framework for the analysis of WWTPs’ behavior and the resulted economic and environmental consequences is presented, and the impacts of discharge standard, charge rate, and penalty rate are analyzed. The trade–offs between the operational cost, environmental impact, and pollutant emissions are identified. This study also provides some insightful management implications for concerned policy makers. [ABSTRACT FROM AUTHOR]

With the development of agriculture in China, the productions of agricultural wastes increase rapidly. The occurrence of agricultural wastes was unique in the different areas. The agricultural straw and livestock excrement are considered to be potential resources. Improper disposition of agricultural wastes not only result in environmental pollution, but also waste a lot of valuable biomass resources. The recycling and utilization of agricultural wastes are considered to be the important step in environmental protection, energy structure and agricultural development. However, the problem in China's current agricultural waste recycling impeded the achievement of scale ecological functions. The objectives of this study were to illuminate the potential environmental risk, recycling and utilization pathway, influencing factors and policy suggestions in the recycling and utilization progress of agricultural wastes. The survey provided the development mode of industrialization and scale of agricultural waste recycling. The recycling and utilization pathway of agricultural wastes were also analyzed. The crucial suggestions were proposed, such as cultivating new industry, building economy incentive standard, improving laws and regulations, and creating rural market strengthening medium and long-term plans of agricultural waste recycling. The resource consumption, ecological crisis and other issues caused by agricultural wastes were evaluated. It will provide more comprehensive fundamental information for the recycling and utilization of agricultural wastes during the modernization and urbanization of China. [ABSTRACT FROM AUTHOR]

The promotion of modern industrialization has caused heavy environmental pollution. Environmental protection is a basic national policy of China. In 2011, China began to implement the "Twelfth Five-Year Plan for National Environmental Protection" (12th FYP_NEP). Using the survey data of small and medium-sized enterprises (SMEs) in Shandong Province of China, this paper empirically explores the impact of 12th FYP_NEP on the energy utilization and operating efficiencies of SMEs. It is found that the environmental policy "12th FYP_NEP" has a significant incentive effect on both efficiency performance of Chinese SMEs, and has a greater positive impact on operating efficiency. Our heterogeneity analysis showed the following results. The incentive effect is different in different industries and enterprises of different sizes. The policy "12th FYP_NEP" has a greater positive impact on the energy utilization efficiency of SMEs in China's first and second tier cities, but it has no significant impact on their operation efficiency. This shows that SMEs in first and second tier cities are more effective in coping with the national environmental policy reform strategy. It can be seen that the promulgation of China's environmental policies can significantly improve the energy utilization awareness of these SMEs. The incentive effect of the policy on the two efficiency performances of SMEs in cities with "heavy air pollution" is greater, indicating that the implementation effect of "12th FYP_NEP" on SMEs in such cities is better. The enlightenments are as follows: the current situation of Chinese SMEs is that the energy utilization efficiency is low, while the operating efficiency is high. Most enterprises attach great importance to their own operating profits and economic development, and the awareness of energy utilization needs to be greatly strengthened. "12th FYP_NEP" has obvious positive effect on the energy utilization and operating efficiencies of SMEs, but there are slight differences among different types of enterprises. It is suggested that governments can refine their own environmental regulation standards and implement different environmental regulations for different types of enterprises, so as to enhance the performance of domestic enterprises most effectively. • This paper used the China survey data on SMEs over the period 2010–2013. • It is found that the Chinese "12th FYP_NEP" has a significant incentive effect on efficiency performance of Chinese SMEs. • The incentive effect is different in different industries and enterprises of different sizes. • The policy makes for improving the energy efficiency of SMEs in first and second-tier cities and heavy-polluted cities. • Chinese SMEs should attach great importance to energy utilization rather than operating profits only.

• Latent Dirichlet Allocation topic model is used to construct political factors. • SBM-DEA model is used to evaluate the ecological efficiency of 36 cities. • Time effect is introduced into FSQCA to analyze the panel data of all cities and four regions. • Differences of the four urban agglomerations are compared. • Analyze the different paths of political factors in 36 cities. Rapid economic development of any country will usually lead to negative environmental impacts. A free market economy cannot fundamentally solve this issue, which requires the guidance and control of the government. The environmental policies of governments can effectively improve the ecological conditions in a region. This study quantifies environmental regulation policies and takes four urban agglomerations in eastern China as the research object to explore the influence of environmental regulation on regional ecological efficiency. First, policies can be divided into policy control, pollution control, ecological protection, and social adjustment by building a Latent Dirichlet Allocation (LDA) model of a policy text library to measure differences in urban policy bias. Next, a slack-based measure (SBM) model was used to measure urban ecological efficiency. Finally, using the qualitative comparison analysis method, the time effect was considered and the ecological efficiency configuration of the entire region was obtained. In addition, contrast analysis was conducted for different path configurations and the reasons of the statuses of the four urban agglomerations were obtained. The results show that policy control, pollution control, ecological protection, and other mandatory policies can significantly reduce the negative environmental effects, especially when the policy controls involve an explicit form of punishment, which is a necessary condition for achieving a high level of ecological efficiency. However, social adjustment means having higher requirements for regional total factor development, which requires improving the environmental awareness of residents and improving corporate social responsibility. Regional differences will mean that areas with a lower level of economic development have a higher intensity of policy control, and the means of policy control should be matched with the level of economic development. In addition, this study proposes some policy suggestions, such as strengthening policy control and pollution prevention, strengthening social regulation, and promulgating environmental laws and regulations according to local conditions.

Abstract: The importance of improving the effectiveness of Plan EIA and SEA-type evaluations in China cannot be overstated: at a time when the country''s economy is being boosted by a stimulus package worth over RMB 400trillion – largely for infrastructure – the pressure on China''s already strained environment and resource base is bound to increase. The aim is to propose the criteria for plan EIA''s effectiveness to raise the awareness of the need to strengthen the performance of the assessment and maximize its potential benefits. The authors first review critically the discourse on the effectiveness of the impact assessment, identifying three dimensions: substantive, procedural and incremental. The resulting conceptual framework allows them to interpret the weaknesses of the Chinese discourse on the effectiveness and of the practice of the Plan EIA to date. The result is the identification of a clear gap, both in terms of the breadth of the concept, and in terms of the quality of the existing criteria, which tend to be very generic to the point of inapplicability. The analysis also reveals a need for transitioning from formal models of the Plan EIA to more strategic approaches, in a gradual manner that is consistent with context-specificities. The proposal of a set of preliminary criteria for effectiveness is therefore structured on three levels. This framework is meant to input into the ongoing debate on how to improve the practice of PEIA and the SEA-type evaluations in China, and provide ideas for a government strategy aimed at maximizing the positive impact of PEIAs on planning, as well as on the context of application.

Abstract: There are many factors have contributed to China''s environmental crisis and are hindering environmental recovery campaigns. In particular, the implementation of government policy has played a strong role, both because of a government''s natural slowness to change and because of structural impediments. Competition for a share of the huge investments that are being made to support environmental protection among various governmental departments and with local governments has also slowed progress. The conflicting socioeconomic policies that can result from this competition have undermined the large investments in environmental programs by failing to consider the environmental consequences of the conflicts, leading to inappropriate actions and compromising the ability to achieve environmental restoration goals. To improve governance and the ability to meet environmental goals, governments at all levels must understand the problem created by the competition that leads to weak coordination of efforts and must formulate revised policies that encourage sustainability by balancing economic growth with a careful consideration of the need for all groups, whether governmental or private sector, to benefit from these policies.
