基于排污许可的环境标准制度改革完善研究

排污许可制度是固定点源环境管理的基础核心制度,政府以排污许可证为载体,对固定污染源的污染物排放限值、排污行为等进行许可,以排放标准的要求作为基本依据,并以环境质量标准为依据,对非达标区实施更为严格的排污许可限制。然而,现有的部分行业排放标准由于制定时间较早、科学技术支撑方法不足、与环境质量改善难以挂钩等问题,难以满足新排污许可证制度改革要求。本文在研究现行环境标准体系对排污许可制度的支撑作用与相互关系的基础上,研究了基于排污许可制的排放标准存在的主要问题,并以健全排污许可制度的环境标准支撑为目的,提出了现行环境标准体系的完善和修订建议。

摩托车头盔与摩托车交通事故的相关研究

我国近年来的摩托车死亡事故占交通事故死亡总数的25％-28％。在我国摩托车使用比较普及的地区,摩托车交通事故数占到该地区交通事故总数的70％-80％,伤亡比例占到总数的50％以上,甚至更高。通过对摩托车交通事故伤亡人员的具体受伤部位分析,发现头部受伤致死的比例非常高,占到该类事故死亡总数75％以上,远远高于其他部位受伤致死率。摩托车驾乘人员头部受伤致死的主要原因是摩托车驾驶乘人员头盔佩戴率低和佩戴的头盔质量差,对头部未能起到应有的保护作用。造成这一局面既有摩托车乘员头盔标准等技术层面存在的问题,又有行业监管等政策层面存在的问题,最后,文章从摩托车头盔标准方面提出了几点修订建议,为规范头盔行业进行基础性的准备。     

特朗普“去气候化”政策对全球气候治理的影响

美国特朗普政府宣布退出《巴黎协定》是当前全球气候治理中最受舆论关注的问题,对事态发展趋势的判断和事件影响的评估是最为亟需的。本文系统分析了特朗普政府上任后推行的一系列"去气候化"政策,以及其退出《巴黎协定》的主要动因和可能形式,同时量化评估了这些内政外交的"倒退"对美国实施国家自主贡献目标以及全球气候治理格局的实质影响,并据此提出了中国应对全球气候治理新形势变化的对策和建议。研究表明,特朗普政府"美国优先"的能源政策根植于复兴制造业和加大基础设施投资的经济利益动机,随着特朗普"去气候化"进程持续发酵,诸多气候政策面临存续风险,美国实施国家自主贡献将面临严峻挑战,"倒行政策"将有可能使美国温室气体排放出现反弹。如果不考虑中、高危气候政策,美国2025年温室气体排放也仅能相对2005年下降11.0%—14.9%,距离下降26%—28%的国家自主贡献目标相去甚远。同时,特朗普政府拒绝继续履行向发展中国家提供气候资金支持的义务,将有可能导致绿色气候基金拖欠资金总额上升117%,并进一步挫伤全球低碳投资的信心。没有美国的全球气候治理3.0时代将呈现出新的复杂特征,并不可避免地造成减排、资金和领导力缺口的持续扩大,也不排除后续会出现消极的跟随者,整体进程将可能进入一个低潮周期。虽然国际社会对中国引领全球气候治理充满期待,但中国仍应审慎对待,长远谋划应对气候变化的内政外交战略,而不应将"气候举旗"看作是一蹴而就的短期策略,对各种要求中国发挥"领导作用"的说法保持清醒头脑。在今后气候谈判中,美国仍有较大可能会二次"要价",中国作为排放大国的压力依然不容小觑,中美气候关系需要再定位。     

Measurement of public awareness of climate change in China: based on a national survey with 4,025 samples

Just before the new round of UN climate change conference in Bonn, a survey report, named as the Climate Change in the Chinese Mind 2017, was released in Beijing. The investigation was conducted in the form of a computer-assisted telephone survey with a sample size of 4,025 samples, covering 332 prefecture-level administrative units and four municipalities in China. Urban-rural proportion and sex proportion were specially taken into account, so as to demonstrate the Chinese public awareness objectively. The investigation measures the public awareness from six aspects, which includes climate change beliefs, impacts, response, policies, actions, and the assessment of the effectiveness of climate communication. This article presents the key findings of the survey and provides further insights behind the data.     

Virtues and humanitarian ethics

This paper analyses the contribution of virtue ethics, the study of good character traits, to the humanitarian context. It argues that a virtue ethics perspective paints a realistic picture of the use of ethical standards in morally complex circumstances. Virtuous relief workers can employ standards in their thinking, but they are also committed to professional excellence that goes beyond any formal code. The concept of virtue ethics places a stress on moral development, which can be facilitated by role models that impart modest and feasible ideals. However, virtue ethics cannot provide simple guidelines on how to resolve difficult situations. It is possible that two virtuous persons can disagree on what should be done in a particular instance. In addition, a virtue ethics perspective emphasises the need for both individuals and organisations to discuss the actual purpose of relief work in order to pinpoint the virtues of a good relief professional.     

构建覆盖国家环境监测网的质量控制体系

"十二五"期间,中国将全面完成国家环境监测网的布局与建设,环境管理将开始由以环境污染控制为目标导向,向以环境质量改善为目标导向转变,以全面考核空气、水环境和土壤等环境质量的新环境管理时代即将来临。从现有环境监测质控体系所发挥的作用、存在的问题以及环境管理的需求出发,提出构建覆盖国家环境监测网的质量控制体系,论述各级环境监测站的质控职责,尤其是省级监测站作为地区质量控制中心,应该和国家站一起加大自身质控能力建设,为提高环境监测数据的可信度做好质控工作。

生活垃圾焚烧炉烟气新标准可达性分析

对《生活垃圾焚烧污染控制标准》(GB 18485—2001)和《生活垃圾焚烧污染控制标准》(GB 18485—2014)中各项指标的排放限值作比较,并探讨了二噁英、重金属、酸性气体、烟尘、碳氧化物等烟气污染物的控制措施。结合2010—2014年浙江省部分生活垃圾焚烧厂"三同时"验收废气监测数据,对排放指标的达标情况作分析,结果表明,采用"3T+E"焚烧工艺+SNCR脱硝+半干法脱酸+活性炭喷射+布袋除尘器除尘的烟气污染控制技术,可以同时满足脱氮、脱酸、除尘,以及去除重金属和二噁英的要求。     

Downgrading,Downsizing, Degazettement,and Reclassification of Protected Areas in Brazil

Protected areas (PAs) are key elements for biodiversity conservation and ecosystem services. Brazil has the largest PA system in the world, covering approximately 220 million ha. This system expanded rapidly in the mid‐1990s to the mid‐2000s. Recent events in Brazil, however, have led to an increase in PA downgrading, downsizing, and degazettement (PADDD). Does this reflect a shift in the country's PA policy? We analyzed the occurrence, frequency, magnitude, type, spatial distribution, and causes of changes in PA boundaries and categories in Brazil. We identified 93 PADDD events from 1981 to 2012. Such events increased in frequency since 2008 and were ascribed primarily to generation and transmission of electricity in Amazonia. In Brazilian parks and reserves, 7.3 million ha were affected by PADDD events, and of these, 5.2 million ha were affected by downsizing or degazetting. Moreover, projects being considered by the Federal Congress may degazette 2.1 million ha of PA in Amazonia alone. Relaxing the protection status of existing PAs is proving to be politically easy in Brazil, and the recent increase in frequency and extension of PADDD reflects a change in governmental policy. By taking advantage of chronic deficiencies in financial and personnel resources and surveillance, disputes over land tenure, and the slowness of the Brazilian justice, government agencies have been implementing PADDD without consultation of civil society. If parks and reserves are to maintain their integrity, there will need to be investments in Brazilian PAs and a better understanding of the benefits PAs provide.
