Policy plays a significant role in accelerating or hindering a circular shift; Governments can set long-term visions and drive legislative change to create an enabling environment. Reflecting the regional picture, Zambia is experiencing increasing waste burdens due to a growing population and economic development. The current management approach is linear, characterized by low collection rates, inadequate disposal, and limited waste revalorization. From a sustainable development perspective, how waste is managed impacts pressing issues such as climate change and public health. The concept of the Circular Economy (CE) has gained global and regional interest given its potential to transform how resources are viewed and managed. Circular strategies may help to reduce waste burdens and create local socioeconomic opportunities while safeguarding the environment. This qualitative study uses document review and expert interviews to explore the current waste management regime in Zambia and understand if and how circularity is embedded into the policy approach. The findings suggest that the CE is potentially highly relevant for Zambia, but there are various policy challenges that could impede its successful integration into the national agenda. These challenges relate to ownership and coordination; gaps in implementation and enforcement; a restrictive licensing approach; obstacles to innovation and new entrants; as well as the role of informal sector actors. The challenges point to opportunities to overturn these policy shortfalls, which also presents future research avenues.
政策在加速或阻碍循环转变方面发挥着重要作用;政府可以制定长期愿景,推动立法变革,创造有利环境。赞比亚的情况反映了该区域的情况,由于人口增长和经济发展,赞比亚的废物负担日益加重。目前的管理方法是线性的,其特点是收集率低、处置不充分和废物再评价有限。从可持续发展的角度来看,如何管理废物会影响到气候变化和公共卫生等紧迫问题。循环经济(CE)的概念已引起全球和地区的关注,因为它有可能改变人们对资源的看法和管理方式。循环战略可能有助于减少废物负担,在保护环境的同时为当地社会经济创造机会。本定性研究利用文件审查和专家访谈来探讨赞比亚当前的废物管理制度,并了解循环是否以及如何被纳入政策方针。研究结果表明,循环经济可能与赞比亚高度相关,但存在各种政策挑战,可能阻碍其成功纳入国家议程。这些挑战涉及所有权和协调;实施和执行方面的差距;限制性许可方法;创新和新进入者的障碍;以及非正规部门参与者的作用。这些挑战为克服这些政策缺陷提供了机会,也为今后的研究提供了途径。

Sustainable development is a global priority. However, a lack of research exists on the programs designed to train sustainable development practitioners. This multi-case case study, possibly the first to describe the programs that trains development practitioners, utilized case study theory and semi-structured interviews with program administrators to describe sustainable development programs offered by 12 higher education institutions in eight countries with membership in the Global Association of Masters in Development Practice. The results revealed five themes or key drivers, nine advantages, and four deficiencies. Two drivers were enrollment-focused (admission of students with prior work experience in development and financial support), two were curriculum-focused (incorporation of field work and integration of specific knowledge aspects and skills training in the curricula), and one was institutional attitude (adoption of a culture of flexibility). The most common challenges were impacts from the COVID-19 pandemic. These results provide insights for continuous improvement efforts of program administrators for students in sustainable development. The practical methodology developed can be replicated and adapted for investigation of similar programs and other disciplines in higher education.
可持续发展是全球优先事项。然而,有关可持续发展从业人员培训项目的研究却十分匮乏。这项多案例研究可能是第一项对培训发展实践者的项目进行描述的研究,它利用案例研究理论和对项目管理人员进行的半结构化访谈,描述了全球发展实践硕士协会 8 个国家的 12 所高等教育机构提供的可持续发展项目。研究结果揭示了五个主题或关键驱动因素、九个优势和四个不足。两个驱动因素以招生为中心(招收有发展工作经验的学生并提供资金支持),两个驱动因素以课程为中心(在课程中纳入实地工作并整合特定知识和技能培训),一个驱动因素以机构态度为中心(采用灵活的文化)。最常见的挑战是 COVID-19 大流行带来的影响。这些结果为可持续发展专业学生课程管理人员的持续改进工作提供了启示。所开发的实用方法可以复制和调整,用于调查高等教育中的类似项目和其他学科。

Changes in consumers’ decision-making relating to food play an important role in the sustainable transition of the food system. However, assessing sustainability across choice alternatives is complex. A holistic or multi-dimensional ‘summary’ sustainability label for food could help consumers make more informed choices, but it is important that such a label is developed taking consumers’ perception and understanding of sustainability into consideration. Hence, it is necessary to understand consumers’ needs and wants in a sustainability food label. The objective of this study is therefore to explore in-depth consumer perceptions and preferences for sustainability as a concept in food production as well as for a sustainability label for food.A total of six online co-creation workshops were carried out in the UK and Ireland (3 groups, n = 24) and Denmark (3 groups, n = 21) using an interactive platform, where participants over the course of two weeks discussed and engaged in creative tasks related to food and sustainability.Results show that consumers in lack information about the sustainability of food products. There were differences with regards to which of 10 pre-tested indicators of sustainability (nature preservation, climate change, animal welfare, fair wages, biodiversity, pollution, health, equality, economic growth and culture) were perceived as most important. The information participants discussed as relevant for a sustainability label included transportation, the degree of processing, and packaging, with some country differences. Consumers acknowledged the complexity of designing and understanding a sustainability food label and existing nutrition labels served as inspiration for creating a sustainability label. Consumers recommended more responsibility to be taken by retailers and food producers through public information campaigns to create awareness.Pros and cons of co-creating a sustainability label with consumers online are discussed as well as the implications for consumers, the food industry and policy makers.
消费者在食品决策方面的变化对食品系统的可持续转型起着重要作用。然而,评估不同选择的可持续性是一项复杂的工作。食品的整体或多维 "概要 "可持续性标签可以帮助消费者做出更明智的选择,但重要的是,这种标签的制定要考虑到消费者对可持续性的看法和理解。因此,有必要了解消费者对可持续性食品标签的需求和愿望。在英国和爱尔兰(3 组,24 人)以及丹麦(3 组,21 人),利用互动平台共开展了六次在线共同创造研讨会,参与者在两周的时间里讨论并参与了与食品和可持续性相关的创造性任务。在 10 个预先测试的可持续发展指标(自然保护、气候变化、动物福利、公平工资、生物多样性、污染、健康、平等、经济增长和文化)中,哪些指标被认为是最重要的存在差异。与会者讨论了与可持续标签相关的信息,包括运输、加工程度和包装,但各国的情况有所不同。消费者承认设计和理解可持续发展食品标签的复杂性,现有的营养标签是创建可持续发展标签的灵感来源。消费者建议零售商和食品生产商通过公共宣传活动承担更多责任,以提高人们的意识。会上讨论了与消费者在线共同创建可持续标签的利弊,以及对消费者、食品行业和政策制定者的影响。

“If less is more, how you keeping score?” Outlines of a life cycle assessment method to assess sufficiency "如果少即是多,你如何记分?评估充足性的生命周期评估方法概要

It is increasingly clear that reaching environmental sustainability requires not only efficiency (reduced environmental impact per functionality) but also sufficiency measures (reduced environmental impact through reduced or changed functionality). Life cycle assessment (LCA) is a widely used tool to study environmental impacts related to consumption. However, because of the LCA convention of only comparing alternative products with equal functionality, it is currently inept as a method for assessing the environmental impacts of sufficiency measures. Against this background, this short paper aims to stimulate a discussion on how sufficiency measures can be assessed with LCA methodology. By analyzing the very few LCAs of explicit sufficiency measures in terms of the components of a functional unit (what function is provided, how much, for how long, and how well) features of a potential new branch of LCA methodology are outlined, called Sufficiency LCA. In Sufficiency LCA, product alternatives need to be similar enough so that the what component of the functional unit can be equal, while the other components, how much, how long, and how well, are allowed to be non-equal. Thus, a key feature of Sufficiency LCA concerns functional non-equivalence of compared product alternatives, which is not allowed or neglected in conventional LCA, but which could be allowed, acknowledged and quantified in Sufficiency LCA. Developing Sufficiency LCA could be critical considering that sufficiency measures are expected to be required, and that LCA is expected to be serviceable as decision-making support, in the transition toward environmental sustainability.
越来越清楚的是,要实现环境的可持续性,不仅需要提高效率(减少每项功能对环境的影响),还需要采取充分措施(通过减少或改变功能来减少对环境的影响)。生命周期评估(LCA)是研究与消费有关的环境影响的一种广泛使用的工具。然而,由于生命周期评估的惯例是只对功能相同的替代产品进行比较,因此目前还不能作为评估充分性措施对环境影响的方法。在此背景下,本短文旨在就如何利用生命周期评估方法评估充足性措施展开讨论。通过分析极少数以功能单元(提供什么功能、提供多少功能、提供多长时间以及提供多好的功能)为基础的明确的充足性措施的生命周期评估,本文概述了生命周期评估方法的一个潜在的新分支--充足性生命周期评估的特点。在 "充足性生命周期评估 "中,产品替代品需要足够相似,以便功能单元的 "什么 "部分可以相等,而其他部分,即 "提供多少"、"提供多长时间 "和 "效果如何",则允许不相等。因此,充足性生命周期评估的一个关键特征是所比较的产品替代品在功能上的不等同性,这在传统的生命周期评估中是不允许的或被忽视的,但在充足性生命周期评估中是可以允许、承认和量化的。考虑到在向环境可持续性过渡的过程中,预计需要采取充足性措施,而且预计生命周期评估可作为决策支持,因此,开发充足性生命周期评估可能至关重要。

This study extends our exploration of the potential of biomass ashes for their CO2-reactivity and self-cementing properties. The ability of three hardwood-based biomass ashes to mineralise CO2 gas and partially replace CEM I in mortars was investigated. The three hardwoods were English oak (Quercus rober), English lime (Tilia x europaea), and beech (Fagus sylvatica). The woody biomass wastes were incinerated at 800°C to extract their key mineral phases, which are known to be reactive to CO2 gas to form carbonates. The selected biomass ashes were analysed for their CO2-reactivity, which was in the range of 32–43% (w/w). The ashes were used to replace CEM I at 7 and 15% w/w and this “binder” was mixed with sand and water to produce cylindrical monolithic samples. These monoliths were then carbonated and sealed cured over 28 days. The compressive strength, density and microstructure of the carbonate-hardened monoliths were examined. The ash-containing monoliths displayed mature strengths comparable to the cement-only reference samples. The CO2 uptake of oak containing monoliths was 7.37 and 8.29% w/w, for 7 and 15% ash substitutions, respectively. For beech and English lime they were 4.96 and 6.22% w/w and 6.43 and 7.15% w/w, respectively. The 28 day unconfined compressive strengths for the oak and beech ashes were within the range of ~80–94% of the control, whereas lime ash was 107% of the latter. A microstructural examination showed carbonate cemented sand grains together highlighting that biomass ash-derived minerals can be very CO2 reactive and have potential to be used as a binder to produce carbonated construction materials. The use of biomass to energy ash-derived minerals as a cement replacement may have significant potential benefits, including direct and indirect CO2 emission savings in addition to the avoidance of landfilling of these combustion residues.
这项研究拓展了我们对生物质灰烬二氧化碳活性和自固结特性潜力的探索。研究了三种硬木类生物质灰烬矿化二氧化碳气体和部分替代灰泥中 CEM I 的能力。这三种硬木分别是英国橡木(Quercus rober)、英国椴(Tilia x europaea)和山毛榉(Fagus sylvatica)。木质生物质废物在 800°C 下焚烧,以提取其主要矿物相,众所周知,这些矿物相会与二氧化碳气体反应生成碳酸盐。对选定的生物质灰烬进行了二氧化碳活性分析,其二氧化碳活性在 32-43%(重量/重量)之间。这些灰烬被用来替代 7%和 15%(重量比)的 CEM I,这种 "粘合剂 "与沙子和水混合,制成圆柱形的整体样品。然后对这些整体石材进行碳化和密封固化,固化时间为 28 天。对碳酸盐硬化整体石块的抗压强度、密度和微观结构进行了检测。含灰单体的成熟强度与纯水泥参考样本相当。在灰分替代率为 7% 和 15% 的情况下,橡木单体的二氧化碳吸收率分别为 7.37% 和 8.29%(重量百分比)。而山毛榉和英国石灰的二氧化碳吸收率分别为 4.96% 和 6.22% w/w,以及 6.43% 和 7.15% w/w。橡木灰和榉木灰的 28 天无压抗压强度在对照组的 ~80-94% 之间,而石灰灰则是对照组的 107%。微观结构检查显示,碳酸盐胶结砂粒在一起,这突出表明生物质灰烬衍生矿物具有很强的二氧化碳反应性,有潜力用作粘合剂来生产碳化建筑材料。使用生物质能源灰渣衍生矿物作为水泥替代品可能会带来巨大的潜在效益,除了避免填埋这些燃烧残留物之外,还可直接和间接地减少二氧化碳排放。

This paper presents a literature review with the aim of facilitating investment funds to understand the practical question of whether investing responsibly can make a fund's portfolios more sustainable without compromising their return/risk profiles. The study contains most of the leading ESG research from the past two decades. We conclude from this research that the relationship between ESG and return/risk profile is predominantly neutral or even positive. Many scholars have found evidence on the performance of stocks, bonds, and real estate. The findings apply to Environmental, Social, and Governance criteria separately and in different regions. We contribute to the body of knowledge accessible to ESG-asset-seeking funds by complementing the impact investment theory and by linking ESG investment to portfolio-level characteristics and investor preferences. Looking into the future, we identify recent trends and developments in this niche field of ESG at the end of the paper.
本文对相关文献进行了综述,旨在帮助投资基金了解这样一个实际问题:负责任的投资是否能使基金投资组合更具可持续性,同时又不影响其回报/风险状况。该研究包含了过去二十年来大部分领先的环境、社会和公司治理研究。我们从这些研究中得出结论,环境、社会和公司治理与回报/风险状况之间的关系主要是中性的,甚至是积极的。许多学者发现了股票、债券和房地产表现方面的证据。这些发现分别适用于不同地区的环境、社会和治理标准。我们对影响投资理论进行了补充,并将环境、社会和治理投资与投资组合层面的特征和投资者偏好联系起来,从而为寻求环境、社会和治理资产的基金所能获得的知识体系做出了贡献。展望未来,我们将在本文末尾指出 ESG 这一利基领域的最新趋势和发展。

Looking into the future, we identify recent trends and developments in this niche field of ESG at the end of the paper.","PeriodicalId":253319,"journal":{"name":"Frontiers in Sustainability","volume":"56 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139533111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For 2030, the Agenda for Sustainable Development sets out 17 goals for sustaining ecological and social growth, known as the Sustainable Development Goals (SDGs), which have mobilized countries around the world to integrate these goals into their national development strategies. However, the Agenda does not explain how these goals are interlinked, which limits their implementation. This paper therefore selects indicator data for 17 SDGs from the World Bank website for four groups of countries to estimate the network structure of the SDGs and the synergies and trade-offs between them, based on the Spearman coefficient. Based on this, the paper further uses a VAR model to identify priority targets among the SDGs and to predict the impact of achieving these targets 2 years earlier on other SDGs. It is found that the SDGs interact with each other in different historical periods, showing both synergies and trade-offs. And as the highest priority goal, the predictions in this paper suggest that SDG 6 has a strong positive impact on SDG 4 and SDG 8. This paper can help policy makers to allocate resources more effectively, maximize benefits, coordinate actions, adapt to future challenges and achieve global sustainable development goals.
2030年,《可持续发展议程》提出了17项可持续生态和社会增长目标,这些目标被称为可持续发展目标(sdg),已动员世界各国将这些目标纳入其国家发展战略。然而,《议程》没有解释这些目标是如何相互联系的,这限制了它们的执行。因此,本文从世界银行网站上选取了17个可持续发展目标的指标数据,对四组国家进行了分析,并基于Spearman系数估算了可持续发展目标的网络结构以及它们之间的协同效应和权衡。在此基础上,本文进一步使用VAR模型确定可持续发展目标中的优先目标,并预测提前2年实现这些目标对其他可持续发展目标的影响。研究发现,可持续发展目标在不同历史时期相互影响,既有协同效应,也有权衡效应。作为优先级最高的目标,本文的预测表明,可持续发展目标6对可持续发展目标4和可持续发展目标8具有强烈的积极影响。本文可以帮助决策者更有效地配置资源,实现利益最大化,协调行动,适应未来的挑战,实现全球可持续发展目标。

Sustainability reporting has become increasingly important to stakeholders, and therefore, there is a growing need for a global set of standards for sustainability reporting. The International Sustainability Standards Board (ISSB) has recently published new sustainability standards under the International Financial Reporting Standards (IFRS) Foundation. The consolidation of integrated reporting into the IFRS Foundation creates the problem of whether there is still a need for principles in the future of sustainability reporting and how these principles will be applied in the standard setting of the ISSB in future. This study provides insights into the similarities and differences between the Framework and the ISSB's draft IFRS S1 standard and clarifies the role that could play in the future of sustainability reporting within the context of the newly issued IFRS S1 standard.The study uses thematic content analysis on the two frameworks and comment letters submitted to the ISSB as part of the standard-setting process to understand the relevance of integrated reporting in sustainability reporting and to identify important principles contained within that can contribute to the ISSB standard-setting process in future.The study identified that there is a largely positive sentiment toward in developing sustainability standards within the IFRS Foundation. The study also identified important aspects where can play a significant role in standard development, such as the connectivity of information, integrated thinking, and the six capitals that can assist organizations in understanding the significant sustainability-related risks and opportunities.The research points out pertinent sustainability principles that could be useful for the ISSB in future standard settings. Furthermore, the research adds to the existing literature on and can act as an impetus for further research on the use of principles in the standard-setting processes of the ISSB.
可持续发展报告对利益相关者越来越重要,因此,越来越需要一套可持续发展报告的全球标准。国际可持续发展准则委员会(ISSB)最近在国际财务报告准则(IFRS)基金会下发布了新的可持续发展准则。综合报告与国际财务报告准则基金会的合并产生了一个问题,即未来的可持续发展报告是否仍然需要原则,以及这些原则将如何在未来的国际会计准则理事会的标准制定中应用。本研究提供了该框架与国际会计准则理事会(ISSB)的IFRS S1标准草案之间的异同的见解,并阐明了在新发布的IFRS S1标准的背景下,该框架在未来可持续发展报告中可能发挥的作用。作为标准制定过程的一部分,该研究使用了对两个框架的主题内容分析和提交给国际会计准则理事会的评议函,以了解综合报告在可持续发展报告中的相关性,并确定其中包含的可能有助于国际会计准则理事会未来标准制定过程的重要原则。研究发现,在国际财务报告准则基金会内部,对制定可持续性标准的态度基本上是积极的。该研究还确定了可以在标准制定中发挥重要作用的重要方面,如信息的连通性、综合思维和六个资本,这些方面可以帮助组织了解与可持续性相关的重大风险和机遇。该研究指出了相关的可持续性原则,这些原则可能对ISSB在未来的标准设置中有用。此外,该研究补充了现有文献,并可作为进一步研究在ISSB标准制定过程中使用原则的动力。

If sustainability is about imagining and pursuing desired futures, our past history, heritage, and culture will influence the kind of futures we seek and our chosen routes towards them. In Scotland, there is a strong connection between culture, land, and identity; a sense of community; and a perception of work ethic that derive from our biogeography and socio-political journey. Concepts and practises of education have been influenced by the ideas of key thinkers such as the Scot Sir Patrick Geddes, who introduced approaches to education and community through concepts such as “heart, hand, and head”, “think global, act local,” and “place, work, and folk”. This background influenced us in establishing Scotland's United Nations University-recognised Regional Centre of Expertise (RCE) in Education for Sustainable Development (ESD), known locally as “Learning for Sustainability Scotland”. Its initial development ten years ago and subsequent evolution have been built on engaging collaboratively across Scotland and linking formal, non-formal, and informal modes of learning for sustainability. In this paper, we explore how culture and context have influenced the emergence, governance, and activities of RCE Scotland over the past decade.We developed an analytical framework of possible cultural and contextual influences on Scottish education. We used a Delphi approach to develop a novel and locally relevant definition of ESD when the RCE was established.Analysis of purposively selected RCE Scotland activities against our cultural framework illustrated how they had been influenced by culture or context. We propose that democratic intellect, local and global, and nature-culture connections have informed our initiative.We conclude that connection to people, place, and nature influences engagement and action on sustainability, and we suggest that additional sustainability competencies should include physical, emotional, and spiritual aspects of nature connection.
如果可持续发展是关于想象和追求理想的未来,那么我们过去的历史、遗产和文化将影响我们所追求的未来和我们选择的通往未来的道路。在苏格兰,文化、土地和身份之间有着紧密的联系;社区意识;以及对职业道德的认知,这源于我们的生物地理和社会政治历程。教育的概念和实践受到了一些重要思想家的思想的影响,比如苏格兰人帕特里克·格迪斯爵士,他通过“心、手和头脑”、“全球思维、地方行动”和“地方、工作和民间”等概念引入了教育和社区的方法。这一背景影响了我们在苏格兰建立联合国大学认可的可持续发展教育(ESD)区域专业知识中心(RCE),在当地被称为“苏格兰可持续发展学习”。它的最初发展是在十年前,随后的发展是建立在整个苏格兰的协作和将正式、非正式和非正式的可持续学习模式联系起来的基础上的。在本文中,我们探讨了在过去的十年中,文化和环境如何影响RCE苏格兰的出现、治理和活动。我们开发了一个分析框架,分析可能的文化和背景对苏格兰教育的影响。当RCE建立时,我们使用德尔菲方法开发了一个新颖且与当地相关的ESD定义。在我们的文化框架下,对有意选择的RCE苏格兰活动进行分析,说明了它们是如何受到文化或背景的影响的。我们认为,民主智慧、地方和全球以及自然与文化的联系为我们的倡议提供了信息。我们的结论是,与人、地点和自然的联系会影响可持续性的参与和行动,我们建议额外的可持续性能力应该包括自然联系的身体、情感和精神方面。
