Given the systemic nature of the circular economy (CE), its successful implementation necessitates a holistic approach involving all the relevant stakeholders across the production and consumption processes. This study focuses on the gap between the demand and supply of circularity by investigating transitioning profiles of consumers and manufacturing companies and examining their symbiotic roles in shaping a systemic circular transition. Using two extensive surveys involving 1000 consumers and 1443 manufacturing companies in Italy, and employing a cluster analysis methodology, we examined pro-environmental purchasing profiles among consumers and varying levels of circular practice integration among companies. The cluster analysis reveals four different consumer cluster based on their attitudes towards CE during the purchasing and post-purchasing phases. While the majority focused only on a single purchasing aspect, approximately one-third consistently optimized, preserved, and enhanced product value throughout the purchase phase and post-purchase use. Conversely, companies were grouped into five clusters according to their varying levels of circularity integration across the product life cycle. Only a small subset of companies fully embraced circularity throughout their entire product life cycle, with most concentrating their efforts on specific phases of the value chain. The findings highlight a significant gap between circular demand and supply: while the biggest cluster of companies comprises linear manufacturers, linear consumers represent the smallest segments. This underscores the need for comprehensive engagement from both manufacturers and consumers in shaping circular production and consumption. Based on a stakeholder perspective, the study opens up a discussion on how to bridge this gap, emphasizing the role of consumers with pro-circular behaviors in pushing companies to integrate circularity principles more thoroughly, and the role of companies in raising the awareness of linear consumers about the impact of their purchasing choices. By profiling circular companies and consumers and unveiling their behavioral tendencies, this research provides actionable insights for policymakers and managers navigating the circular transition.

鉴于循环经济（CE）的系统性，其成功实施需要一种涉及整个生产和消费过程中所有相关利益方的整体方法。本研究通过调查消费者和制造企业的转型概况，重点关注循环需求和供应之间的差距，并研究他们在形成系统性循环转型中的共生作用。通过对意大利的 1000 名消费者和 1443 家制造企业进行两次广泛调查，并采用聚类分析方法，我们研究了消费者的环保采购概况和企业的不同循环实践整合水平。聚类分析根据消费者在购买和购买后阶段对消费环保的态度，揭示了四个不同的消费者聚类。虽然大多数消费者只关注单一的购买方面，但约有三分之一的消费者在整个购买阶段和购买后的使用过程中始终坚持优化、保护和提高产品价值。相反，根据企业在整个产品生命周期中不同程度的循环整合，企业被分为五个组别。只有一小部分公司在其整个产品生命周期中完全接受了循环性，大多数公司将其努力集中在价值链的特定阶段。研究结果凸显了循环需求与供应之间的巨大差距：最大的企业集群由线性制造商组成，而线性消费者则占最小的部分。这凸显了生产商和消费者全面参与塑造循环型生产和消费的必要性。基于利益相关者的视角，本研究就如何缩小这一差距展开了讨论，强调了支持循环行为的消费者在推动企业更全面地融入循环原则方面的作用，以及企业在提高线性消费者对其购买选择的影响的认识方面的作用。通过对循环型企业和消费者进行剖析，揭示他们的行为倾向，这项研究为政策制定者和管理者在循环转型过程中提供了可操作的见解。

Mobile phone recycling is crucial to recover valuable resources and mitigate environmental health risks. Collection campaigns may help to retrieve unused phones, but empirical evidence on the factors contributing to the effectiveness of such campaigns is rare. In the present study, we assessed how one and the same collection campaign was implemented in N = 124 Belgian schools with over 30,000 students and related between-school variations in implementation characteristics to the number of collected phones (8,931 in total). More phones were collected in schools that assigned a higher priority to the collection campaign (r_s = .42) and in schools that reported a higher degree of teacher involvement (r_s = .36). All schools also received collection-contingent rewards and we randomly offered some schools the opportunity to donate this reward, but this manipulation did not lead to significant between-school differences. These results support the effectiveness of the evaluated collection campaign and can inform the design of future efforts to collect unused mobile phones.

手机回收对于回收宝贵资源和降低环境健康风险至关重要。回收活动可能有助于回收未使用的手机，但有关此类活动有效性因素的实证证据并不多见。在本研究中，我们评估了在拥有 30,000 多名学生的 N = 124 所比利时学校中如何实施一项相同的收集活动，并将学校之间的实施特点差异与收集的手机数量（共 8,931 部）联系起来。在对收集活动给予更高的优先级（rs = 0.42）和教师参与度更高（rs = 0.36）的学校中，收集到的电话数量更多。所有学校也都收到了有收集条件的奖励，我们还随机为一些学校提供了捐赠奖励的机会，但这一操作并未导致校际间的显著差异。这些结果证明了评估收集活动的有效性，并为今后收集闲置手机的设计提供了参考。

The growing trend of decluttering has spurred many consumers to streamline their wardrobes by removing excess garments. However, garment decluttering has not received much attention in the academic research. This study employs a mixed methods approach to explore how reflective garment decluttering can be related to sufficient clothing consumption by investigating 1) consumers’ motivations to declutter and the methods used, 2) the influence of reflective decluttering on consumers' perceptions of their clothing items and consumption habits, and 3) the impact of reflective decluttering on long-term clothing acquisition and strategies for maintaining sufficient clothing consumption. Qualitative analysis reveals that motivations for decluttering include reducing garment over-ownership, creating space, and finding emotional relief. Participants gained insights into the value of their garments, their reasons for possession, and their consumption habits, helping them establish future consumption goals. Quantitative findings from a longitudinal survey add to the qualitative insights by showing that reflective decluttering was associated with reduced clothing acquisition, although a slight rebound occurred after six months. The qualitative findings also reveal strategies including conscious shopping and extending garment life cycles that reduce consumption levels and promote sufficiency-oriented practices over time.

日益增长的衣物整理趋势促使许多消费者通过去除多余衣物来精简衣橱。然而，服装整理在学术研究中并没有得到太多关注。本研究采用混合方法，通过调查：1）消费者整理衣物的动机和使用的方法；2）整理衣物对消费者对衣物的看法和消费习惯的影响；3）整理衣物对长期购置衣物的影响以及保持足够衣物消费的策略，来探讨反思性衣物整理如何与足够的衣物消费相关联。定性分析显示，整理的动机包括减少衣物的过度拥有、创造空间和寻找情感慰藉。参与者对其衣物的价值、拥有衣物的原因以及消费习惯有了深入的了解，这有助于他们确立未来的消费目标。纵向调查的定量研究结果补充了定性研究结果，表明反思性整理与衣物购买量减少有关，尽管六个月后略有反弹。定性研究结果还揭示了一些策略，包括有意识地购物和延长服装的生命周期，这些策略可以降低消费水平，并促进长期的以充足为导向的做法。

This study explores the role of ODTÜ Bostan (METU Garden), a community garden at the Middle East Technical University in Turkey, in promoting sustainability education, ecology, and food consumption practices. For ten years, ODTÜ Bostan has been a collaborative space where participants—including students, academic and non-academic staff, and their families—grow and share food using ecological agricultural methods. This research examines how this community garden creates a setting for alternative and interdisciplinary learning, supporting practical engagement, critical thinking, and community interaction for community participants. Drawing on the Education for Sustainable Development and transformative learning frameworks, this qualitative study employs autoethnography, thematic analysis of eight semi-structured interviews, and content analysis of archival data. The findings indicate that ODTÜ Bostan not only enhances participants' sustainability competencies but also serves as an educational laboratory, demonstrating the potential of community gardens to address global challenges such as climate change and biodiversity loss. The study highlights the importance of integrating interdisciplinary and learner-centered approaches in higher education leading to collective action for societal change toward sustainability.

The fashion industry plays a pivotal role in societal evolution and economic growth, yet it also stands as a significant contributor to environmental degradation. In response, the concept of slow fashion has been gaining increased attention in recent years, offering sustainable and circular alternatives to fast fashion. Luxury fashion, traditionally known for its heritage, exclusivity, and craftsmanship, exhibits elements similar to slow fashion, thereby exerting considerable influence on industry trends and consumer behaviour. This study explores the drivers shaping the luxury fashion landscape and the evolving circular economy and sustainability trends within the UK, a key global influencer in the luxury fashion domain. Luxury fashion's impact extends beyond its niche market, often setting benchmarks for innovation and sustainable practices that influence the broader fashion industry. Leveraging readily available qualitative and quantitative data from LinkedIn profiles, this research employs Latent Dirichlet Allocation analysis to uncover relevant topics within a dataset comprising 1115 companies registered in the “Apparel and Fashion” and “Textiles” industries. Five key drivers emerge, including Artful Creations in Fashion, Time-Honoured Craftsmanship, The Art of Style and Design, The Pinnacle of Retail Excellence, and A Personalised Style Experience. Additionally, utilising the Google Collab Platform and Python language, this study identifies circular economy and sustainability trends within luxury fashion. While approximately 20% of the companies studied actively emphasise sustainability, circular economy requires comparable attention. This research provides industry stakeholders and scholars with valuable insights into sustainable and circular practices, thus guiding innovation and informed decision-making in the fashion industry.

时尚产业在社会演变和经济增长中发挥着举足轻重的作用，但同时也是造成环境退化的重要因素。为此，近年来 "慢时尚 "的概念受到越来越多的关注，它为快速时尚提供了可持续发展和循环利用的替代品。传统上以传承、独特性和手工艺著称的奢侈时尚，表现出与慢时尚类似的元素，从而对行业趋势和消费者行为产生了相当大的影响。英国是全球奢侈时尚领域的重要影响者，本研究探讨了塑造奢侈时尚格局的驱动因素，以及英国不断发展的循环经济和可持续发展的趋势。奢侈时尚的影响超越了其利基市场，往往为创新和可持续实践设定基准，从而影响更广泛的时尚产业。本研究利用 LinkedIn 资料中现成的定性和定量数据，采用 Latent Dirichlet Allocation 分析方法，从 "服装与时尚 "和 "纺织品 "行业 1115 家注册公司的数据集中发掘相关主题。由此产生了五个关键驱动因素，包括时尚中的艺术创造、历久弥新的工艺、风格与设计的艺术、卓越零售的顶峰以及个性化的风格体验。此外，本研究还利用谷歌协作平台和 Python 语言，确定了奢侈时尚领域的循环经济和可持续发展趋势。在所研究的公司中，约有 20% 积极强调可持续发展，而循环经济则需要同等的关注。这项研究为行业利益相关者和学者提供了有关可持续发展和循环实践的宝贵见解，从而为时尚行业的创新和明智决策提供指导。

The global event and convention industry is singlehandedly one of the largest and most lucrative sectors in business forecasting market size projected at approximately more than two trillion U.S. dollars by 2028. Despite being a significant contributor to global economic growth, the event and convention industry faces a pressing environmental challenge due to its substantial carbon footprint. Current practices in the industry inadequately address sustainability concerns, leading to a critical gap in integrating environmental considerations into core business models. The lack of sustainability considerations contributes to climate degradation and undermines the industry's long-term success and resilience. This observation signifies the need for a more systematic trajectory toward total decarbonization of the industry through the implementation of sustainable practices across its value chain. This work aims to develop a conceptual framework of sustainability assessment for a case study in the event and convention sector integrating two indicators: greenhouse gas emissions and energy consumption. The result identified a critical gap in current practices regarding the insufficient integration of sustainability assessment into the core financial business models of firms. The authors propose a new approach to address this by integrating economic impact analysis through the employment of the Return of Sustainability Investments – discovered as the most effective sustainability economic impact assessment method in this study. To facilitate optimized implementation, a multilevel strategy framework enabling the adoption of a sustainability assessment is presented in this paper. This paper contributes to improved execution of sustainability assessments, where the framework can be applied in heterogeneous sectors.

据预测，到 2028 年，全球会展业的市场规模将超过两万亿美元。尽管活动和会议业对全球经济增长做出了重大贡献，但由于其巨大的碳足迹，该行业面临着紧迫的环境挑战。该行业目前的做法未能充分解决可持续发展问题，导致在将环境因素纳入核心业务模式方面存在重大差距。缺乏可持续发展方面的考虑会导致气候退化，并损害该行业的长期成功和复原力。这一观察结果表明，有必要通过在整个价值链中实施可持续发展实践，以更系统的方式实现该行业的全面去碳化。这项工作旨在为活动和会议行业的一项案例研究开发一个可持续发展评估概念框架，其中整合了两个指标：温室气体排放和能源消耗。研究结果发现，目前的实践中存在一个重要的缺陷，即没有将可持续发展评估充分纳入企业的核心财务商业模式。作者提出了一种新的方法来解决这一问题，即通过使用可持续发展投资回报率来整合经济影响分析，这是本研究中发现的最有效的可持续发展经济影响评估方法。为促进优化实施，本文提出了一个可采用可持续性评估的多层次战略框架。本文有助于改进可持续性评估的执行，该框架可应用于不同部门。

This research presents a clear overview of greenwashing practices in the food industry, along with instances in the academic literature. In this work, a bibliometric analysis covering over 711 articles from the Scopus database was carried out. According to the findings, research on greenwashing in general has expanded dramatically in the previous ten years, indicating an increasing importance for the upcoming years. While greenwashing is an established phenomenon in the food industry and an emerging topic among consumers, relatively few research papers are available on the subject; this review identified 16 papers that met the inclusion criteria. The review offers a detailed analysis of these papers. Key factors contributing to greenwashing practices in the food industry include advertising, access to information, transparency, knowledge, trust, and labelling. The review also identifies six major subtopics that significantly influence the food industry: retailers, corporate social responsibility, consumer research, food supply chain, and stakeholders. This study aims to serve as a valuable reference for policymakers and scholars who are determining the future path of greenwashing research. This review also aligns with the focus of the research agenda of several nations, and the EU, to act firmly against greenwashing practices and deceptive environmental claims.

本研究清楚地概述了食品行业的 "绿色清洗 "做法以及学术文献中的实例。在这项工作中，对 Scopus 数据库中超过 711 篇文章进行了文献计量分析。研究结果表明，在过去十年中，有关 "绿色清洗 "的研究总体上急剧增加，这表明其重要性在未来几年将不断增加。虽然 "绿色清洗 "在食品行业是一种既定现象，在消费者中也是一个新兴话题，但有关这一主题的研究论文却相对较少；本综述确定了 16 篇符合纳入标准的论文。本综述对这些论文进行了详细分析。造成食品行业 "洗绿 "行为的主要因素包括广告、信息获取、透明度、知识、信任和标签。综述还确定了对食品行业有重大影响的六大子课题：零售商、企业社会责任、消费者研究、食品供应链和利益相关者。本研究旨在为决策者和学者提供有价值的参考，帮助他们确定 "绿色清洗 "研究的未来发展方向。本综述也与一些国家和欧盟的研究议程重点一致，即坚决打击绿色清洗行为和欺骗性环境声明。

Alternative consumer networks (ACNs) have become increasingly important for promoting sustainable development. This study provides a conceptual clarification of ACNs and systematically reviews their impact on sustainable development. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we identified 218 peer-reviewed references that report on sustainability outcomes of ACNs at different levels, including determinants of motivation, contextual changes, behavioral changes, and social, ecological, and economic impacts. Our findings demonstrate that ACNs have a multifaceted influence on sustainability, highlighting the interconnected nature of various outcomes. This holistic approach captures the broad and significant role ACNs play in advancing sustainable practices across multiple dimensions of sustainability. We synthesized these results into a comprehensive logic model, which serves as a practical tool for systematically assessing the impact of ACNs. This model helps practitioners focusing on relevant outcomes and to develop and implement effective strategies tailored to their specific contexts. Additionally, it provides researchers with a structured framework for further study, facilitating a deeper understanding of the dynamic relationships between different sustainability outcomes.

<div><p>In Bangladesh, the role of harvested wood (e.g. wood products and associated processing residues) to mitigate climate change is less known and often ignored. This study aims to understand the substitution impacts of harvested wood products and associated processing residues in Chattogram city area, Bangladesh. Additionally, we also explored sellers' and users' perceptions towards the use of wood biomass and associated effects, with users’ level of satisfaction with using different categories of products of wood, bamboo, steel, and plastic. The study only considered sawn wood from sawmills to the wooden furniture and building materials, and associated residues, but excluded carbon in the forest ecosystem. A survey, using three different types of pre-tested questionnaires consisting of open and close-ended questions, was carried out in 36 sawmills, 62 timber merchants, and 55 furniture manufacturers or shops, with their owners or managers in Chattogram City Corporation area, Bangladesh. We used the general displacement factors of 0.5, 0.45, 1, and 1.3 tC tC<sup>−1</sup> for processing residues, composite wood furniture, solid wood furniture, and building materials, respectively. The amount of wood products and associated residues and their avoided emissions due to substitution were presented in m<sup>3</sup> industry<sup>−1</sup> year<sup>−1</sup> and Mg industry<sup>−1</sup> year<sup>−1</sup>. Results revealed that the highest mean annual consumptions of timber (783.95 m<sup>3</sup> industry<sup>−1</sup> year<sup>−1</sup>) and processing residues (196.05 m<sup>3</sup> industry<sup>−1</sup> year<sup>−1</sup>) were in the sawmills and the lowest (60.56 and 0.66 m<sup>3</sup> industry<sup>−1</sup> year<sup>−1</sup>) in the furniture manufacturers. Altogether, the processing of round logs generated 36% residues of its mass from sawmilling to furniture manufacture. Sawn wood (of sawmills and timber merchants) consumed in the building houses produced the highest annual avoided emissions (1029.51 Mg CO<sub>2</sub> industry<sup>−1</sup> year<sup>−1</sup>). The development of efficient products with long lifespans, in addition to factors such as forest management, emissions, waste generation, and life cycle assessments of products likely play a significant role in determining the overall impact on displacement factors. The future study should focus on developing material flow analysis integrated with a life cycle assessment approach for various products for the construction and associated sectors, thus generating a country-specific displacement factor. The perception-based study documented that wood furniture and processing residues as bioenergy were perceived as a good substitute for non-wood furniture (e.g., steel, plastic) and fossil fuels (gas, oil) and thus lowering fossil emissions as wood products were perceived as user-and-environment-friendly and attractive. However, environmental awareness of both consumers and sellers about wood and bioe

在孟加拉国，伐木（如木制品和相关加工残留物）在减缓气候变化方面的作用鲜为人知，而且往往被忽视。本研究旨在了解孟加拉国 Chattogram 市地区伐木制品和相关加工残留物的替代影响。此外，我们还探讨了销售商和用户对使用木材生物质及其相关影响的看法，以及用户对使用木材、竹子、钢材和塑料等不同类别产品的满意程度。研究只考虑了从锯木厂到木制家具和建筑材料的锯材以及相关残留物，但不包括森林生态系统中的碳。我们使用三种不同类型的预先测试问卷（包括开放式和封闭式问题），对孟加拉国 Chattogram 市公司地区的 36 家锯木厂、62 家木材商、55 家家具制造商或商店的所有者或管理者进行了调查。我们对加工残留物、复合木家具、实木家具和建筑材料分别使用了 0.5、0.45、1 和 1.3 吨碳 tC-1 的一般转移因子。木制品和相关残留物的数量及其因替代而避免的排放量以 m3 工业-1 年-1 和 Mg 工业-1 年-1 表示。结果显示，锯木厂的木材年平均消耗量（783.95 立方米工业-1-年-1）和加工残渣年平均消耗量（196.05 立方米工业-1-年-1）最高，而家具制造商的消耗量（60.56 立方米工业-1-年-1 和 0.66 立方米工业-1-年-1）最低。从锯木到家具制造，圆木加工共产生了 36% 的剩余物。建筑房屋消耗的锯材（锯木厂和木材商）每年产生的避免排放量最高（1029.51 兆克 CO2 工业-1-年-1）。除了森林管理、排放、废物产生和产品生命周期评估等因素外，开发使用寿命长的高效产品也可能在决定对位移因素的总体影响方面发挥重要作用。今后的研究应侧重于针对建筑及相关行业的各种产品，结合生命周期评估方法，开展材料流分析，从而得出针对具体国家的位移系数。基于认知的研究表明，木制家具和作为生物能源的加工残留物被认为是非木制家具（如钢材、塑料）和化石燃料（天然气、石油）的良好替代品，从而降低了化石排放，因为木制品被认为是对用户和环境友好且有吸引力的。然而，消费者和销售者对木材和生物能源的使用以及森林退化的环境意识，对于将其从中性观念转变为积极观念至关重要。

Despite the fact that domestic rice production contributes significantly to the livelihood of millions of people in Ghana, it has been observed that consumers show a strong preference for expensive and imported rice over locally produced rice. The purpose of this study was to investigate the perception, purchasing behaviour and determinants of local rice consumption across three income households in the Kumasi Metropolis, Ghana. A total of 414 rice consumers were selected through a multi-stage sampling technique. Descriptive and inferential techniques, including perception analysis and ordered probit model, were used to analyse the data. The overall perception index of 3.61 denotes that consumers generally have a positive perception of local rice regarding health benefits (index = 4.44), affordability (index = 3.86), and cooking attributes (index = 3.48), despite its poor appearance (index = 2.80). The ordered probit model depicted heterogeneity of covariates as determinants of local rice consumption-based income strata of the household. For instance, various factors, including gender, age, occupation, and attributes of local rice such as affordability, nutrition, cooking attributes, and appearance, have a notable impact on the consumption of local rice among low-income households. In contrast, education, household decision-making, the place of purchasing local rice, and three perception attributes, namely affordability, nutrition, and cooking attributes, were found to be significant determinants of local rice consumption among middle-income households. According to the data, local rice consumption among high-income families was significantly predicted by gender, occupation, household size, and two perception attributes—affordability and nutrition. The study has practical implications for improving the competitiveness of local rice to increase its acceptance and consumption among consumers in the country.

尽管国内大米生产为加纳数百万人的生计做出了重大贡献，但据观察，与本地生产的大米相比，消费者对昂贵的进口大米表现出强烈的偏好。本研究的目的是调查加纳库马西大都市三种收入家庭对本地大米消费的看法、购买行为和决定因素。通过多阶段抽样技术，共选取了 414 名大米消费者。数据分析采用了描述性和推论性技术，包括感知分析和有序概率模型。总体感知指数为 3.61，表明消费者普遍对本地大米的健康益处（指数 = 4.44）、可负担性（指数 = 3.86）和烹饪属性（指数 = 3.48）持积极看法，尽管其外观较差（指数 = 2.80）。有序概率模型显示，协变量的异质性是基于家庭收入阶层的本地大米消费的决定因素。例如，各种因素，包括性别、年龄、职业和本地大米的属性，如经济实惠、营养、烹饪属性和外观，对低收入家庭本地大米的消费有显著影响。相比之下，教育程度、家庭决策、购买本地大米的地点以及三个感知属性，即经济实惠、营养和烹饪属性，则是中等收入家庭消费本地大米的重要决定因素。数据显示，性别、职业、家庭规模和两个感知属性（可负担性和营养）对高收入家庭的本地大米消费量有明显的预测作用。这项研究对于提高本地大米的竞争力，增加其在国内消费者中的接受度和消费量具有实际意义。
