Planning and implementing sustainability in higher education institutions: an overview of the difficulties and potentials

Planning in sustainable development is believed to be an important element in allowing higher education institutions to set their goals and to commit themselves towards undertaking concrete actions and measures at all levels in order to implement sustainability. Yet, there is a paucity of research that has looked at the extent to which planning can support institutions of higher education to assess their performances and to determine whether the set aims have been met. This research gap needs to be met to allow a better understanding of how planning can help to promote the integration of the three components of sustainable development – economic development, social development and environmental protection in higher education. This paper explores the challenges for planning the sustainable development in higher education, also outlining the potentials lessons learned that could assist in improving Education for Sustainable Development efforts in Higher Education Institutions. Among its main results are the fact that many universities wish to pursue sustainable development, but their efforts are hindered by lack of institutional support and planning and limited emphasis on approaches, such as problem-based learning. The universities that are engaged in the field have to face many problems, varying from limited resources to lack of trained staff. As a result, integrated approaches to sustainability become difficult to implement. Finally, the paper has identified the fact that many opportunities offered mainstream developments, such as the UN Declaration ‘The World we Want’ or the UN Sustainable Development Goals are not being put to full use.     

International trade,carbon leakage,and CO2 emissions of manufacturing industry

Foreign trade drives China’s growth,but as the trade scale continues to expand,the carbon emissions also increase quickly.Based on the industry panel data from 1996 to 2010,this paper calculates carbon emissions of 27manufacturing industries.According to the intensity of carbon emissions,this paper divides the manufacturing sectors into low carbon and high carbon manufacturing industry and then analyzes the carbon emission trends.Next,the paper uses the feasible generalized least square regression to verify the existence of environmental Kuznets curve（EKC）of the manufacturing industry’s carbon.In order to investigate the carbon leakage problem,the regression also includes the interaction term between trade and industrial value added.Our findings are as follows:the carbon emissions of the whole manufacturing industry and low carbon manufacturing industry accord with the EKC curve,but have a linear relationship with the high carbon manufacturing industry;trade reduces the carbon emissions of the whole manufacturing industry and low carbon manufacturing industry,but it increases those of the high carbon manufacturing industry;for the whole manufacturing industry and low carbon manufacturing industry,there is no carbon leakage,but it exists in the high carbon manufacturing industry.On the whole,pollution haven hypothesis does not hold up in China,and China does not need to limit industry foreign trade to reduce the emission of CO₂.But the manufacturing industry will still be the main engine of the economic growth,and therefore our country should make an effective low-carbon policy,introduce advanced technology,increase R&D investment into lowcarbon technologies,and upgrade and transform the original equipment to change the backward mode of production.

Building resilience to climate change – the role of cooperation in alpine tourism networks

While there is ample – though partially contradictory – evidence regarding the effects climate change will have on various regions of the world, there is only very limited work dedicated to the analysis of different governance structures, and how these structures are likely to influence the resilience of alpine tourism systems in the face of climate change. We present an analytical framework based on network theory, and apply this to the Swiss case study destination of Engelberg, in order to deduct a number of insights for the future assessment of resilience based on the cooperation of local actors. The main aim of the paper is to come up with comparable resilience metrics based on social network analysis in order to assess the structural strengths and weaknesses of a geographically delimited tourism system in the face of climate change. Together with the action potential of the individual actors these structural properties influence the adaptive capacity of both individual actors, and the tourism system as a whole. In line with comparable studies, we identify structural strengths and weaknesses around the core-periphery distribution (centrality), subgroups (modularity) and information flows (path length). We find that the Engelberg network follows an almost ideal-typical scale-free structure and the overall cooperation rate (density) is comparable to other tourism networks. The main weaknesses of the network with regard to climate change resilience are the lacking integration of public sector actors and the relatively high number of actors in the periphery of the network.     

新型污染物风险防范国际实践及其对中国的启示

随着重化工业的快速发展和各类化学品的大量使用，一些新型污染物对中国居民和生态环境的危害正逐步显现并日趋严重。如何进一步完善中国新型污染物的风险防范体系，是中国生态环境治理面临的重要问题。发达国家新型污染物的风险防范工作启动较早，对中国完善新型污染物风险防范体系具有重要的借鉴意义。本文从制度建设、体制机制、评估监测、科学研究等方面比较国内外新型污染物风险防范实践的异同，立足我国国情，发现国内实践还需加强之处。在此基础上，提出国际新型污染物风险防范实践对中国的启示。

中国环境质量拐点:基于EKC的实证判断

促进环境质量改善是"十三五"时期实现绿色发展和最终全面建成小康社会的重要目标和任务。随着经济进入新常态和环境治理政策的强势推进,中国环境质量是否已经跨越峰值和进入持续改善的通道?本文基于环境库兹涅茨曲线这一理论工具,依据环境统计数据和国际经验事实判断中国是否到达环境库兹涅茨曲线的拐点和具备促使环境质量持续改善的经济特征。首先,应用中国各省份1998—2013年的面板数据,对人均收入水平与主要大气污染物排放的关系进行回归拟合发现,人均烟粉尘排放自1998年以来持续下降,人均二氧化硫、氮氧化物排放均在"十二五"中前期到达峰值。大部分东部省份已经越过环境库兹涅茨曲线的拐点,但环境质量改善仍然缓慢。多数中部省份处于峰值阶段,而西部省份大都处于经济增长与环境质量恶化的矛盾阶段。其次,基于污染物排放的驱动因素框架,将中国当前的经济特征与美、日、韩三国跨越环境库兹涅茨曲线拐点的经验进行比较,结论表明中国目前已基本具备了跨越环境库兹涅茨曲线拐点的经济驱动条件,但是相对滞后的城镇化进程将会导致污染物排放峰值的扁平化和波动性。以主要污染物排放在2014年的基础上削减30%—40%作为环境质量全面改善的转折点判断,中国环境质量将在2025年左右趋于全面改善。最后,为了促进环境质量全面改善,认为应该根据各地区经济发展与环境污染形势的不同,实施差别化环境治理政策。同时积极防范新一轮城镇化过程中的环境风险,进一步强化区域环境污染的协同治理。     

中国虚拟水贸易的测算及影响因素研究

本文测算2005年、2007年与2010年3个年度中国虚拟水进出口贸易量,采用投入产出及IO-SDA等方法分解分析其变化的影响因素。研究结果显示部门间用水系数差距都非常大,直接用水系数最大的农业部门857.9 t/万元(3年平均值,下同),与直接用水系数最小的部门差距达600倍之多。完全用水系数最大的也为农业部门1 078.7 t/万元,与完全用水系数最小的部门亦达113倍。各部门的完全用水系数和直接用水系数也存在较大不同,有些部门完全用水系数和直接用水系数差距很大,如服装皮革羽绒及其制品业部门差距达115倍,食品制造及烟草加工业部门差距达618.5 t/万元;而有些部门差距非常小,如农业部门差距仅仅0.24倍,煤炭开采和洗选业部门差距仅为8.2 t/万元。虚拟水出口量和进口量分别从2005年的1 774.3亿t和1 378.7亿t增加到2010年的2 254.1亿t和1 836.5亿t,且出口量一直大于进口量。影响因素分解显示,在此期间,进出口规模的增加是虚拟水贸易量增加的主要影响因素,其中出口规模合计为103 698.8×10~6t,进口规模合计为80 401.2×10~6t。进出口贸易结构的影响在不同部门间存在较大的差异。真实用水系数和真实中间投入技术是虚拟水贸易变化的主要负向因素,其中真实用水系数对虚拟水出口与进口的影响分别为-36 793.2×10~6t和-34 668.3×10~6t,真实中间投入技术对虚拟水出口与进口的影响分别为-1 719.7×10~6t和-1 660.8×10~6t,表明在此期间用水效率和中间投入效率都得到了改善。另外,直接用水系数和中间投入技术分解出的结构效应都不明显,中间投入进口比率效应也不明显。     

中国国际贸易隐含碳文献比较研究

贸易中的隐含碳流动对中国的二氧化碳排放具有重要影响。从现有的文献来看,尽管出现了大量的针对中国贸易中隐含碳的相关研究,但由于数据及方法的不同,结果之间存在较大差异,很大程度上影响了研究结果的科学性和应用价值。本文对现有的中国国际贸易隐含碳文献进行了比较研究,结果发现:不同研究得出了相对一致的结论,但在隐含碳的具体数量上差异巨大。定性来看,中国是一个隐含碳净出口国,净出口量呈现出逐年增加的趋势。定量来看,1997-2007年,中国隐含碳出口量从3.1-8.8亿t增长到17.2-30.2亿t二氧化碳;隐含碳进口量从1.0-7.0亿t增长到5.8-16.5亿t二氧化碳;隐含碳净出口量从1.8-7.3亿t增长到11.4-22.6亿t二氧化碳;隐含碳净出口量占国内总排放量的比重由5%-20%增长到17%-30%。贸易中隐含碳核算结果的不确定性主要来自三个方面:核算方法产生的不确定性、数据融合产生的不确定性以及原始数据引入的不确定性。总体来看,多区域投入产出模型的研究结果相对稳定,可重复性较高;从数据精度和数据可获得性方面考虑,40个左右的部门分类可以取得较为理想的结果:把中国划分为多个区域研究国际贸易中的隐含碳在理论上更加可靠。国家气候变化对外谈判和国内减排目标的实现都需要对碳排放进行精确管理。在未来的研究中,应重视隐含碳核算的不确定性研究,逐步提高隐含碳核算的精度,更好地服务于国家的气候变化政策。     

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。
