Voluntary and active participation by a wide variety of actors is a prerequisite for successful societal transitions towards sustainability. The ‘Commitment to Sustainable Development 2050’ is a national-level initiative in Finland, aiming to mobilise a large-scale transition involving various societal actors through openly communicated commitments to concrete actions. Each commitment should focus on at least one of the eight nationally defined sustainability objectives connected to the global Sustainable Development Goals. This article assesses the implementation and the development needs of the commitment process based on a range of materials. The results highlight the importance of securing adequate resources for long-term coordination and continuous development of the commitment process, trust creation through long-term and open communication, and flexibility allowing for experimentation aimed at finding new modes of interaction between the public and private sectors. 相似文献

河流水质的动态马尔柯夫评价 总被引:3,自引:0,他引:3
根据马尔柯夫过程的原理,在水质级别评价结果的基础之上,构造水质变化的概率转移矩阵,并对转移概率赋权计算绝对进步度,然后在此基础上引出相对进步度的概念,用相对进步度来评价河流水质在一段时期内的变化程度.运用该方法计算了中国四大河流2005年的水质相对进步度,并对计算结果进行了分析. 相似文献

党的十九大提出“统筹发展和安全”的要求,构建相应的“安全—发展”协同治理绩效评估体系成为迫在眉睫的任务。通过运用社会基本矛盾、社会主要矛盾、社会主要矛盾主要方面的理论原理,构建“发展—应急—满意度”(Development-Contingencies-Degree of Satisfaction,DCD)的三角形绩效分析框架,设立经济发展、安全责任制、科学管理、依法行政、公共服务、安全感等一级指标,探讨若干二级和三级指标,构建“安全—发展”协同治理绩效评估指标体系框架,为检验常态与应急态协同绩效治理水平提供尺度。 相似文献

中国人口基数大、发展水平低、人均资源占有量少的特点以及巨大燃煤量也导致中国环境污染问题愈发严重,决定了中国必须向发展低碳经济转变.中国应通过提高能源使用率,减少资源消耗,开发可再生能源等途径,削弱资源对经济发展的限制.虽然中国的基本国情和发展现状使中国向低碳经济发展转变的难度较大,但是发达国家实施低碳经济转型的实践活动为中国发展低碳经济提供了许多宝贵的经验,让中国发展低碳经济的过程中少走许多弯路,使中国向低碳经济更好的发展. 相似文献

This paper evaluates the planning competences required to enact a managed transition to sustainability at the municipal level for cities facing population, economic and employment decline. Drawing on the ‘shrinking cities’ literature, we argue consolidation of the built environment can become a focal point for sustaining citizen welfare when transitioning cities that are facing decline, especially those previously reliant on resource industries. We evaluate the former coal mining city of Yubari, Japan, which is developing a consolidated urban form with the aim of creating a ‘sustainable’ future city. Findings from interviews and content analysis of Yubari’s planning policy indicate, however, that to translate ‘shrinking’ a city into a managed transition, spatial planning must be accompanied by a wider range of social policy measures and strong cross-sectoral engagement. We also caution that the unique geographical and political context of Yubari mean its model may not be directly replicable in other contexts. 相似文献

This study deals with the German Federal Government’s approach of ensuring public support for its ‘Energiewende’, the swift and complete transition to an energy system based on renewable sources. First, the government’s ‘consensus management’ strategy is described as consisting of four elements: the setup of stakeholder deliberation fora; the funding of organisations dedicated to the public promotion of the energy transition; public campaigns that appeal to people’s commitment and the support of research on energy technologies. The study then traces the need for a strong social mandate of the energy transition back to the scope of the regulatory challenge and the recently growing conflicts around implementation, to institutional constraints of a consensus democracy and to the narrative of ‘Energiewende’ as the ‘grand national task’. 相似文献

ZrO2负载过渡金属氧化物催化剂对CO+NO(O2)反应的影响 总被引:6,自引:0,他引:6
本文运用固定床微反技术考察了Cu,Fe,Mn,Cr,Co和Ni负载(ZrO2载体)氧化物对CO+NO(O2)反应的催化活性。研究了NO和CO在不同比例时,催化剂对N2O和N2生成的影响。结果表明,在NO+CO反应中,NO和CO的比例对催化剂活性和N2O,N2生成均有明显的影响,CuOx/ZrO2催化剂的活性最高;N2O是NO+CO反应的中间产物,低温或NO过量时有利于生成N2O,高温或NO不足时有 相似文献
