Hazardous waste management (HWM) in chemical industrial parks is an important issue related to sustainable development. Previous researches concentrations on HWM have been transferred from technologies, economic, and ecological benefits to social relations because the coordination and cooperation among different stakeholders determine the efficiency of HWM. To analyze stakeholder coordination in HWM, this paper employed a mixed-method combined with stakeholder analysis(SA) and social network analysis(SNA), for analyzing interests, powers, attitudes, knowledge of different stakeholders, and the characteristics, power quantification of the stakeholders' coordination network, by chosen Shanghai Hangzhou bay economic and technical development park(SHDP) as a case study area. In hazardous waste management, governmental supervision has enough interest but less power and with the complete knowledge on, third-party supervision has a medium interest but less knowledge to support their supervision, firms have the lowest power but interest, waste treatment and disposal company have most power and interest but limited knowledge. NGOs, research institutes and media have interest and knowledge but less power. Most stakeholders have positive attitude. We also find that local supervisions play an important role in stakeholder coordination, and NGOs and research institutes have the most potential to push stakeholder coordination by improving information exchange. Therefore, policy recommendations are proposed, including the establishment of communication mechanisms, the adoption of hazardous treatment regulations and economic instruments, the application of a platform for information exchange, and the encouragement of stakeholders' engagement and public participation.

Environmental infrastructure investment (EII) is an important environmental policy instrument on responding to greenhouse gas (GHG) emission and air pollution. This paper employs an improved stochastic impact by regression on population, affluence and technology (STRIPAT) model by using panel data from 30 Chinese provinces and municipalities for the period of 2003–2015 to investigate the effect of EII on CO2 emissions, SO2 emissions, and PM2.5 pollution. The results indicate that EII has a positive and significant effect on mitigating CO2 emission. However, the effect of EII on SO2 emission fluctuated although it still contributes to the reduction of PM2.5 pollution through technology innovations. Energy intensity has the largest impact on GHG emissions and air pollution, followed by GDP per capita and industrial structure. In addition, the effect of EII on environmental issues varies in different regions. Such findings suggest that policies on EII should be region-specific so that more appropriate mitigation policies can be raised by considering the local realities. [ABSTRACT FROM AUTHOR]

Metal production from mineral resources is crucial for economic development. However, most mining activities usually target short-term financial benefits, rather than long-term consideration on ecological sustainability. To better understand the impact of metal production, systematic evaluation methods should be applied to complement current economic accounting tools. Under such a circumstance, this study proposes an emergy-based metal production evaluation framework, taking a life cycle perspective from the formation of mineral deposit to the final production of metal. Ecosystem service loss, CO2 emissions, and emissions' impact are quantified, evaluating the comprehensive performance of a lead and zinc production system in Yunnan Province of China. The results show that minerals contribute significantly to the formation of lead and zinc production; however, emergy received in terms of money substantially undervalues environmental work associated with production. Such a metal production system relies heavily on nonrenewable resources and put enormous pressures on local ecosystems. The beneficiation subsystem generates the highest negative impact per emergy output, followed by the smelting and refining subsystem and the underground mining subsystem. From climate change point of view, producing 1 ton of lead bullion leads to 1.79E+03 kg CO2eq. Electricity use contributes a dominated share to the total CO2 emission of all subsystems. In addition, lead recycling can greatly reduce the overall CO2 emission, indicating that it is necessary to build up a regional lead collection and recycling system. Finally, several policy suggestions are raised by considering the local realities, aiming to promote sustainable development of this industry. [ABSTRACT FROM AUTHOR]
