Simulative governance: on the collaborative narrative of civil society participation in the CDM stakeholder framework

The Kyoto Protocol’s Clean Development Mechanism (CDM) is often cited as an exemplar of new, hybrid forms of global environmental governance operating at the public–private interface. Practically, enacting this arrangement involves a wide range of non-state actors. This broad involvement is here assumed to mark a shift towards more polycentric and networked modes of governance in which agents collaborate as ‘stakeholders’ in the process of consensual rule-setting and implementation. Using post-political critique, the depoliticising effects of the stakeholder framework on civil society actors are interrogated, using formal and informal participation opportunities to raise concerns regarding specific CDM projects. The analysis suggests that the CDM’s collaborative narrative of stakeholding structurally fails to stimulate public (re)engagement and is, instead, a prime example of simulative governance that struggles to achieve the simultaneity of two incompatibilities: the participatory revolution and the post-political turn.     

结合《土壤污染防治行动计划》探讨中国土壤环境监管制度与标准值体系建设

2016年,中国国务院印发《土壤污染防治行动计划》(简称《土十条》),明确提出对农用地土壤实施分类管理,按照污染程度划分为优先保护类、安全利用类和严格管控类;对建设用地要防范新增污染,针对疑似污染地块,开展土壤环境状况调查评估,保障地块安全再利用;以影响农产品质量和人居环境安全的突出环境问题为重点,制定土壤污染治理与修复规划,组织开展治理与修复。实施严格的土壤环境质量保护、污染土壤的风险管控、高风险污染土壤的治理与修复是落实《土十条》的重要任务,也是建设我国土壤环境监管制度的重要内容。土壤环境标准是实施土壤环境管理的重要依据。本文基于《土十条》重要任务以及当前及今后一段时期国家土壤环境管理需求,以土壤环境管理需求为导向,探讨提出了包括土壤环境质量保护标准值、土壤环境风险管控标准值、污染土壤修复标准值的土壤环境标准值体系,可望为国家土壤环境标准体系的建立和标准制修订方法的发展提供技术参考。     

国外学术界对《巴黎协定》的评价及履约前景分析

2016年《巴黎协定》的正式生效是全球环境治理的重要里程碑,是国际社会在应对气候变化的艰难进程中迈出的重要一步,标志着全球环境治理从此进入履约阶段。本文基于宾夕法尼亚大学智库与公民社会项目(TTCSP)公布的《2015年全球智库指数报告》,选取其中排名前十位的国际环境智库的研究报告和环境领域中代表性学者的相关论文,对国外学术界有关《巴黎协定》履约前景的分析进行了系统梳理,并对此做出简要评述。文章在肯定《巴黎协定》有力推进国际气候治理进程的同时,也指出在新的国际形势之下,尤其是在英国正式启动脱欧进程和特朗普新任美国总统后,其履约过程中更是存在着协定之内和协定之外的众多挑战和不确定性,本文的基本结论如下:首先,协定之内面临着协定缔约方国内批准程序上的挑战;国家自主贡献的实现与发展中国家能力建设;2℃温升目标的实现前景;审评和盘点的效力评估;碳市场机制能否有效运行。其次,协定之外面临着英国脱欧的潜在气候政策变化及影响;美国气候政策的可能变化及其影响。基于对以上智库报告和相关研究论文的分析,笔者对《巴黎协定》的履约前景得出几点看法:(1)正视国际气候合作的机遇与挑战;(2)对具体议题的落实需充满信心;(3)理性冷静看待英美气候政策的可能变化;(4)鼓励环境类国际组织之外的非国家行为体展开通力合作。对此,我们应正视履约中的挑战与不确定性,做好充分的应对之策,确保履约进程的顺利完成。总之,《巴黎协定》的履约前景不容乐观,国际社会任重道远。

Local air pollution and global climate change taxes: a distributional analysis for the case of Spain

Global climate change measures are difficult to implement. In this context, local air pollution measures may play an important role in the political agenda since their effects are felt more immediately by citizens. Distributional implications are one of the main barriers for implementing environmental policies. This paper explores the distributional implications of air pollution taxes and compares them to climate change taxes. For the comparison, both tax schemes were set to yield the same revenue. Methodologically, the study uses a top–down approach linking a macro model to a micro model. We find that taxes on local air pollutants are more regressive than those levied on CO₂. This is because the goods implicitly taxed have a greater weight in the consumer basket of low-income groups, even if the tax revenues are recycled. Furthermore, the revenue-neutral recycle scheme increases both taxes efficiency, but, at the same time, can increase regressivity.     

反应气耦合等离子体降解沙林模拟剂

采用水蒸气、氨气、过氧化氢气雾和臭氧4种气体对沙林模拟剂氟磷酸二异丙酯(DFP)进行降解研究,发现臭氧对DFP具有较好的降解作用,在流量200 L/h,DFP初始浓度50 mg/m3时,降解率最高可达56.1%。对高浓度DFP(大于80 mg/m3)进行降解研究时,等离子体单独作用最高降解率为89%,而添加臭氧后的降解率都在95%以上。计算得到臭氧作用的能量利用率为0.05 mg/(W·h),等离子体的能量利用率为0.55 mg/(W·h),而添加臭氧后的等离子体能量利用率为0.68 mg/(W·h)明显高于臭氧和等离子体能量利用率之和,因此对高浓度DFP进行处理时,臭氧与等离子体存在耦合作用。对等离子体和臭氧耦合等离子体降解DFP反应进行了产物分析,发现主要的降解产物基本一致,但是臭氧的存在能使降解更加彻底。     

高氯酸钾项目生产过程中的环境风险及防范措施

根据国家环保总局发布的"高污染、高环境风险"产品名录(2009年),无机盐产品高氯酸钾属于高环境风险的产品,其生产存在较大风险。高氯酸钾项目在生产过程中的环境风险主要来源于强酸、强碱、有毒有害、易燃易爆等原辅材料、产品,运输、贮存和使用过程产生的燃爆、泄漏、贮运风险以及工艺废气治理措施失效等环节。识别项目产生的环境风险主要包括爆炸风险、泄漏风险、危险化学品贮运风险及氯气直排风险,并从生产管理、生产工艺及贮运等方面提出相应的防范措施。     

Regional impervious surface estimation: an urban heat island application

This paper describes a GIS-based estimation method that can be used to forecast future amounts of impervious surface as a mitigation measure for urban heat island effect in a metropolitan region. The method is unique because it employs a regression model that links the existing amount of impervious surface to population and employment at the census tract level. This approach provides a means to forecast future amounts of impervious surface based on projected population and employment. The method also includes a detailed analysis of high-resolution aerial photography to divide impervious surfaces into different categories. Subdividing impervious surfaces is necessary to evaluate potential urban heat island mitigation policies for different types of impervious surface. The analysis here shows that the impervious surface in the metropolitan Atlanta region will increase to 2638 km2 2. “The Albedo is defined as the hemispherical reflectivity averaged over the solar spectrum. A perfect reflector has a = 1, and a perfect absorber has a = 0” (Pomerantz et al. 1999 Pomerantz, M. 1999. Reflective surfaces for cooler buildings and cities. Philosophical magazine B, 79: 1457–1476. [Taylor & Francis Online], [Web of Science ®] [Google Scholar], p. 1458). View all notes in 2030, an increase of 45% from 2000. The most common type of impervious surface is dark-coloured pavement. Within this study area, the analyses showed that two-thirds of impervious surfaces are dark. Replacing dark pavement with light pavement materials, therefore, represents an important opportunity to mitigate the urban heat island effect in the Atlanta region.
