住宅遭受交通噪声污染时开发商应承担的民事责任初探

从分析住宅遭受交通噪声污染时开发商民事责任的性质入手,探讨了现行声环境质量标准对开发商的适用性和合理性,阐明了开发商的责任范围,提出了完善住宅声环境质量标准的建议。主要结论:目前我国尚缺乏合理的约束开发商的住宅声环境质量标准;开发商的隔声减噪义务主要包括留出与道路之间的防噪距离和采取安装隔声窗、封闭阳台等隔声措施;应将门窗封闭状态下的室内噪声限值颁布为住宅声环境质量标准。

Estimating the extent and structure of trade in horticultural orchids via social media

The wildlife trade is a lucrative industry involving thousands of animal and plant species. The increasing use of the internet for both legal and illegal wildlife trade is well documented, but there is evidence that trade may be emerging on new online technologies such as social media. Using the orchid trade as a case study, we conducted the first systematic survey of wildlife trade on an international social‐media website. We focused on themed forums (groups), where people with similar interests can interact by uploading images or text (posts) that are visible to other group members. We used social‐network analysis to examine the ties between 150 of these orchid‐themed groups to determine the structure of the network. We found 4 communities of closely linked groups based around shared language. Most trade occurred in a community that consisted of English‐speaking and Southeast Asian groups. In addition to the network analysis, we randomly sampled 30 groups from the whole network to assess the prevalence of trade in cultivated and wild plants. Of 55,805 posts recorded over 12 weeks, 8.9% contained plants for sale, and 22–46% of these posts pertained to wild‐collected orchids. Although total numbers of posts about trade were relatively small, the large proportion of posts advertising wild orchids for sale supports calls for better monitoring of social media for trade in wild‐collected plants.     

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。     

中国低碳发展的国际比较研究——基于历史和经济发展阶段的审视

随着近年来我国碳排放总量的增加,一些西方国家开始把碳减排责任的矛头指向中国。为了明确中国碳排放的国际地位,运用历史唯物主义观点,从经济发展阶段视角进行了国际比较研究。首先运用IEA2011年公布的碳排放数据分析了我国2009年面临的碳排放形势,继而研究了工业革命以来中国碳排放的总体贡献情况,最后从经济发展阶段视角进行了国际比较研究。认为:①尽管我国当前的碳排放总量巨大,但人均碳排放量低于世界前10名的主要碳排放国家,碳排放强度与世界主要碳排放国家相比还存在一定差距;②我国的历史累计碳排放贡献及人均碳排放均较低,发达国家和地区的累计碳排放量达到世界累计碳排放量的近3/4;③与发达国家相同经济发展阶段相比,我国的人均碳排放和碳排放强度远低于主要发达国家和地区;④世界主要发达国家和地区在快速推进工业化的经济发展阶段普遍伴随着高碳排放。鉴于此,我们认为应该辩证地看待中国的碳排放,一方面中国当前的确产生了较大的碳排放,另一方面中国的经济发展阶段决定了这种碳排放规模和水平。发达国家的经济发展轨迹和碳足迹也表明,在工业化快速推进的过程中,一定程度的高碳排放是世界经济发展的客观规律。     

Analysis of the Energy Embodied in Foreign Goods Trade of China

In recent years, scientists have been increasingly interested in the energy embodied in traded goods among countries. In this article, the direct energy intensities in various economic sectors of China were calculated with the data of energy consumption and output value of each sector, and the input-output table was used to estimate the external energy consumption. The total energy intensity of all sectors was then obtained. From the data of international trade, the energy embodied in goods trade of China was estimated for the period of 1994-2001. During this period, the average energy intensity of imported goods was always higher than that of exported ones. As a country with a surplus in international goods trade, China actually imported net embodied energy in the past few years. The net embodied energy imported was at the same magnitude of the imported energy in the form of fossil fuels.     

China-Indian Silk Trade： Current Production and Future Prospects

As an important traditional labor-intensive industry of both India and China, the cocoon silk industry has long made great contributions to the ecological environment protection, rural economic development and the increase in export income of both countries. India is not only a very important cocoon silk trading partner, but an important production competitor of China. In recent years, there has been a large increase in the production and trade of the cocoon silk between China and India; however, China relies heavily on Indian market, which leads to a tendency of further deterioration in the silk trade environment between both countries. The present article makes an empirical study of the cocoon silk resources of the two countries and the scale, product mix and market structure of China-Indian silk trade from 2001 to 2007. Overall silk trading volumes from China to India and market concentration rate are on the increase because of the superiority of Chinese cocoon silk production over that of India. Owing to scattered market share and export that mainly focused on raw materials product, there has been a phenomenon of price reduction and quantity increase. India carries out fierce competition with China in the international market and even imposes antidumping sanction on Chinese silk, which are key factors restricting further increase between China-India trade. Based on the abovementioned facts, the authors aim to put forward suggestions for steadily developing the production and trade of China＇s silk.     

全球绿色低碳发展与公平的国际制度建设

在可持续发展和扶贫框架下发展绿色经济与国际可持续发展制度建设及改革是当前世界可持续发展的核心和关键,也是"里约+20"峰会的两个主题。首先,绿色经济是体现经济社会与资源环境相协调和可持续发展的根本途径。绿色经济的核心是以低的自然资源消费、低排放、低污染,达到高的自然资源利用效益,实现高的经济社会发展水平,提供高的生活水平和优良的生活环境。全球绿色经济的发展潮流,将引发社会形态由"工业文明"向"生态文明"转变。虽然经济发展和消除贫困是发展中国家当前首要和压倒一切的优先任务,但也必须探索新型的绿色低碳工业化和现代化道路,在实现工业文明的过程中,努力建设生态文明,实现跨越式发展。同时积极应对全球绿色低碳转型中新的经济、贸易、技术竞争规则和格局的变动,加强先进技术创新,提升自身的低碳竞争力。其次,公平获取可持续发展的理念,应成为国际可持续发展制度建设和改革的基本原则。可持续发展要求既要促进经济社会发展与资源环境相协调,促进"代际公平",又要关注欠发达地区消除贫困,提高生活质量,改善生态环境,实现"国别公平"、"人际公平"。因此,国际可持续发展制度框架的建设和改革,要体现世界各国公平获取可持续发展的理念和原则,全面均衡地反映不同国情和发展阶段国家的利益诉求。主要表现在公平享有全球环境空间、公平获得现代优质能源服务、公平适应全球环境变化、公平承担责任义务及公平的国际制度和机制。中国需要统筹国内外两个大局,走中国特色的绿色低碳发展之路。最后,中国的国情和发展阶段特征,在可持续发展领域又面临比发达国家更多的困难和更严峻的挑战。在全球发展绿色经济,努力实现可持续发展的大背景下,中国要统筹国际国内两个大局,协调推进。在国际上积极参与国际制度的建设和改革,在促进全球经济发展,社会进步和环境保护等方面发挥积极的建设性的作用。在国内加强可持续发展战略的实施,走绿色、低碳和可持续发展的路径。主要战略对策包括加速转变发展方式,强化节能优先,控制能源消费总量和CO2排放总量的过快增长;加强能源结构的低碳化,逐步建立并形成以新能源和可再生能源为主体的可持续能源体系;加强城乡统筹,地区平衡,促进生态城市建设;适应国际可持续发展制度改革的趋势,加强绿色低碳和可持续发展的制度建设;抓住机遇,顺应世界绿色低碳发展潮流,自主实现发展方式的转变,把传统的资源依赖型、粗放扩张的发展方式转变到新型的技术创新型、内涵提高的发展方式上来,基本走上绿色低碳和可持续发展的轨道。
