The growing amount of waste originating from food packaging has increased both practical and scholarly interest in the technological development, design and marketing of sustainable food packaging. This article, in turn, scrutinizes the sustainability of packaging from the consumer perspective, arguing that the sustainability of a package is entangled not only in the content of the packaging but also in the functions it fulfills, and that the conditions for acceptable sustainable food packaging from the consumers' perspective differ from the packaging industry's views. We examine the meanings of the packaging functions for consumers based on the data collected through an online consumer panel in Finland. The findings show that while the containment function of packaging plays the most important role for the consumer in general, the informative function is particularly relevant from the viewpoint of sustainability. Moreover, we identified two novel functions consumers highly appreciate –usability and disposability – that are largely irrelevant from the industry perspective. The findings provide important insights in the transformation to more sustainable food packaging and in the development of novel packaging solutions.

源于食品包装的废弃物日益增多,使人们对可持续食品包装的技术开发、设计和营销产生了更大的实际兴趣和学术兴趣。本文则从消费者的角度审视包装的可持续性,认为包装的可持续性不仅与包装的内容有关,还与包装的功能有关,而且从消费者的角度来看,可接受的可持续食品包装的条件与包装行业的观点不同。我们根据通过芬兰消费者在线小组收集的数据,研究了包装功能对消费者的意义。研究结果表明,虽然包装的容纳功能对消费者来说是最重要的,但从可持续发展的角度来看,包装的信息功能尤为重要。此外,我们还发现了消费者非常欣赏的两个新功能--可使用性和可抛弃性,而这两个功能在很大程度上与行业的观点无关。这些发现为向更具可持续性的食品包装转型和开发新型包装解决方案提供了重要启示。

Social media platforms have a key role in spreading narratives about climate change, and therefore it is crucial to understand the discussion about climate change in social media. The discussion on anthropogenic climate change in general, and social media specifically, has multiple different narratives. Understanding the discourses can assist efforts of mitigation, adaptation, and policy measures development. In this work, we collected 333,635 tweets in English about anthropogenic climate change. We used Natural Language Processing (NLP) and machine learning methods to embed the semantic meaning of the tweets into vectors, cluster the tweets, and analyze the results. We clustered the tweets into four clusters that correspond to four narratives in the discussion. Analyzing the behavioral dynamics of each cluster revealed that the clusters focus on the discussion of whether climate change is caused by humans or not, scientific arguments, policy, and conspiracy. The research results can serve as input for media policy and awareness-raising measures on climate change mitigation and adaptation policies, and facilitating future communications related to climate change.

社交媒体平台在传播有关气候变化的叙述方面发挥着关键作用,因此,了解社交媒体中有关气候变化的讨论至关重要。关于人为气候变化的讨论,具体到社交媒体,有多种不同的说法。了解这些论述有助于减缓、适应和政策措施的制定。在这项工作中,我们收集了 333,635 条关于人为气候变化的英文推文。我们使用自然语言处理(NLP)和机器学习方法将推文的语义嵌入向量,对推文进行聚类,并对结果进行分析。我们将推文聚类为四个群组,与讨论中的四个叙述相对应。通过分析每个聚类的行为动态,我们发现这些聚类主要集中在气候变化是否由人类造成、科学论证、政策和阴谋的讨论上。研究成果可作为媒体政策和气候变化减缓与适应政策宣传措施的参考,并促进未来与气候变化相关的传播。

The climate impact of food is rapidly gaining attention. Studies focus on global and national impacts, marginalising the role and preferences of individual consumers. Diet is highly personal and for changes to be widely adopted they should be consistent with peoples' lifestyles, preferences, tastes, and knowledge. We construct global scenarios of reducing meat consumption and model their carbon mitigation potential to 2050. We conduct a simple survey to explore UK consumers' preferences for different approaches to reducing meat consumption, which are used to develop scenarios, and units for communicating the associated portion sizes and emissions savings. Results from our survey suggest that modest reductions in meat consumption are more resonant (e.g., eating three portions per week) rather than absolutes (becoming vegan for one month) or abstractions (consuming 170 cal of meat per day). Similarly, tangible analogies such as number of airline flights are preferred over raw emissions abated. We find that reducing meat intake to recommended healthy levels (92 cal per day) and avoiding ruminant meat could almost halve production-phase GHG emissions from the food system. Our survey illustrates how such information can be rephrased for more engaging communication: “reducing your meat intake to three times per week is equivalent to avoiding six short-haul return flights each year”.

食品对气候的影响正迅速引起人们的关注。研究侧重于全球和国家影响,而忽视了个人消费者的作用和偏好。饮食是高度个人化的,要使饮食变化得到广泛采用,就必须符合人们的生活方式、偏好、口味和知识。我们构建了减少肉类消费的全球情景,并模拟了到 2050 年的碳减排潜力。我们进行了一项简单的调查,以探索英国消费者对减少肉类消费的不同方法的偏好,这些偏好被用于制定情景方案,以及宣传相关的份量和减排量的单位。我们的调查结果表明,适度减少肉类消费(例如每周吃三份)比绝对减少(一个月成为素食主义者)或抽象减少(每天摄入 170 卡路里的肉)更能引起共鸣。同样,有形的类比(如乘坐飞机的次数)比原始的减排量更受欢迎。我们发现,将肉类摄入量减少到建议的健康水平(每天 92 卡路里)并避免食用反刍动物肉类,几乎可以将食品系统生产阶段的温室气体排放量减少一半。我们的调查说明了如何重新表述这些信息,以便进行更有吸引力的宣传:"将您的肉类摄入量减少到每周三次,相当于每年避免六次短途往返航班"。

Assessment of urban heat Island vulnerability using sustainability-focused framework: A case study of Thailand's Bangkok Metropolis 利用以可持续性为重点的框架评估城市热岛脆弱性:泰国曼谷大都市案例研究
IF 3.7 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2024-01-01 DOI: 10.1016/j.crsust.2024.100262

This research assesses the urban heat island (UHI) vulnerability of Thailand's Bangkok metropolis using a sustainability-focused assessment framework which encompasses three vulnerability components: exposure, sensitivity, and adaptive capacity. In the assessment, the UHI vulnerability indicators are used to determine the extent and magnitude of UHI vulnerability. In addition, the UHI vulnerability indicators are aligned with the three pillars of sustainability: social equity, economic viability, and environmental protection. The results show that, under the exposure component, the indicators related to land surface temperature and impervious surface area have high to very high UHI exposure indicator scores. Under the sensitivity component, the indicators related to built environment, green spaces, and water bodies exhibit high to very high UHI sensitivity indicator scores. Under the adaptive capacity component, the indicators associated with government policy and action, multi-agency collaboration, and access to climate control appliances require corrective action. The metropolis- and administrative district-level UHI vulnerability indexes identify the extent and magnitude of UHI vulnerability of different urban areas, with high exposure and high sensitivity indexes and low adaptive capacity indexes contributing to high UHI vulnerability. Essentially, the findings enable urban planners and policymakers to formulate effective strategies to mitigate the impacts of UHI and enhance the city's resilience.

本研究采用以可持续性为重点的评估框架,对泰国曼谷大都市的城市热岛(UHI)脆弱性进行了评估,该框架包含三个脆弱性组成部分:暴露程度、敏感性和适应能力。在评估过程中,我们使用了特高气温易损性指标来确定特高气温易损性的范围和程度。此外,超高温影响指标还与可持续发展的三大支柱(社会公平、经济可行性和环境保护)相一致。结果表明,在暴露部分,与地表温度和不透水表面积相关的指标具有较高或非常高的特高压暴露指标得分。在敏感性部分,与建筑环境、绿地和水体相关的指标显示出较高至非常高的超高温影响敏感性指标得分。在适应能力部分,与政府政策和行动、多机构合作以及获得气候控制设备相关的指标需要采取纠正行动。大都市和行政区一级的特高温易损性指数确定了不同城市地区的特高温易损性程度和规模,高暴露指数和高敏感性指数以及低适应能力指数导致了特高温易损性高。从根本上说,这些研究结果有助于城市规划者和决策者制定有效的战略,以减轻特高温影响并提高城市的抗灾能力。

The purpose of the European Green Deal and the regulation associated with the so-called EU Taxonomy for Sustainable Activities is to lead capital flows towards sustainable investments. According to the European Commission this is necessary to finance solutions for the immense challenges ahead, such as climate change, social inequality, and loss of biodiversity. However, academic research raises concerns that sustainable investments may earn lower risk-adjusted returns in the long run. The European Supervisory Authorities identify greenwashing risks and pronounce the limited ability of retail investors to make informed investment decisions. The aim of this perspective article is to provide suggestions for a regulation on relevant information on sustainable investments provided by financial service providers to retail investors. Therefore, the existing regulations are put in relation with recent research on investments considering ESG issues. To enable retail investors' self-determined decision-making, financial service providers such as banks, mutual funds, and financial advisors must provide easily accessible, clear, and easily understandable information regarding the ESG-conformity of the offered financial products. In addition, financial service providers must inform retail investors about some specific risks that can arise from a narrow focus on ESG assets such as under-diversification, an overweight of large stocks, and returns that can be lower than the market return.

欧洲绿色交易 "和与所谓的 "欧盟可持续活动分类标准 "相关的法规旨在引导资本流向可持续投资。根据欧盟委员会的说法,这是为应对气候变化、社会不平等和生物多样性丧失等未来巨大挑战提供资金解决方案所必需的。然而,学术研究担心,从长远来看,可持续投资可能会获得较低的风险调整回报。欧洲监管机构发现了 "洗绿 "风险,并指出散户投资者做出明智投资决策的能力有限。本视角文章旨在就金融服务提供商向散户投资者提供可持续投资相关信息的法规提出建议。因此,本文将现行法规与近期有关考虑环境、社会和公司治理问题的投资研究联系起来。为使散户投资者能够自主决策,银行、共同基金和财务顾问等金融服务提供商必须提供易于获取、清晰易懂的信息,说明所提供的金融产品是否符合 ESG 标准。此外,金融服务提供商还必须告知散户投资者一些因狭隘地关注 ESG 资产而可能产生的特定风险,如分散化不足、超配大型股票以及回报可能低于市场回报等。

The rapid urbanization and rural-urban migration trends have led to an increase in building construction activities, shifting from traditional practices to modern concrete structures. However, this transition has imposed significant environmental pressures, including heightened resource and energy demands, resulting in increased emissions. To gauge the environmental impact of construction, a thorough examination of each phase is crucial. This study used the Life Cycle Assessment (LCA) tool, based on ISO 14040:2006, ISO 14044:2006, and EN 15978:2011, to evaluate the carbon dioxide equivalent (CO2-eq) emissions throughout the complete life cycle of a modern single-family residential building. The findings reveal a total energy use of 6411.33 MJ per square meter and emissions of 718.35 kg CO2-eq per square meter over the building's lifespan of 50 years. Notably, the production of building materials and the construction phase contribute to the highest percentage (60.29%) of the total life cycle emissions owing to 49.51% of energy use. In contrast, emissions during the operational phase are relatively lower, attributed to increased electricity usage for cooking and minimal energy consumption for heating and cooling. Additionally, the study suggests that achieving complete electricity sufficiency within the country could reduce building emissions by 39.30%, as fossil fuel-based imports from India would be replaced with cleaner hydroelectricity.

快速城市化和农村人口向城市迁移的趋势导致建筑活动增加,从传统做法转向现代混凝土结构。然而,这种转变带来了巨大的环境压力,包括资源和能源需求增加,导致排放量增加。要衡量建筑对环境的影响,对每个阶段进行彻底检查至关重要。本研究根据 ISO 14040:2006、ISO 14044:2006 和 EN 15978:2011,使用生命周期评估(LCA)工具,评估了现代单户住宅建筑在整个生命周期中的二氧化碳当量(CO2-eq)排放量。研究结果表明,在建筑 50 年的生命周期内,每平方米的总能耗为 6411.33 兆焦耳,每平方米的二氧化碳排放量为 718.35 千克。值得注意的是,由于 49.51% 的能源使用量,建筑材料的生产和施工阶段的排放量占生命周期总排放量的比例最高(60.29%)。相比之下,运行阶段的排放量相对较低,原因是烹饪用电量增加,而供暖和制冷的能耗最小。此外,研究还表明,在印度国内实现电力完全充足可使建筑排放量减少 39.30%,因为从印度进口的化石燃料将被更清洁的水力发电所取代。

Additionally, the study suggests that achieving complete electricity sufficiency within the country could reduce building emissions by 39.30%, as fossil fuel-based imports from India would be replaced with cleaner hydroelectricity.</p></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666049024000057/pdfft?md5=8791b2a6ca8c6cd8adfcf8f4fb1666bd&pid=1-s2.0-S2666049024000057-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139941834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of biochar application on crop yield has always been a topic of concern. However, most current research focuses on the short-term effects of biochar on crop growth. Investigating the long-term effects of biochar in increasing crop yields is crucial for food security and sustainable agricultural development. To address this issue, this study performed a coupling of meta-analysis and structural equation model (SEM) based on the establishment of a dataset containing 981 sets of observations. The results demonstrated that biochar significantly and durably boosted crop yield, and biochar also has shown an average increase of 36.2% in SOC over a monitoring period exceeding 2 years. Crop yields increased by an average of 16% after biochar application for the long-term scale, although the increase varied across crop types, and biochar application performed better on corn and wheat than paddy rice production. It is noteworthy that the yield still increased by 15% on average after 6 years of biochar application. According to SEM, the yield increase was positively correlated with the application amount of biochar, and the yield increase was higher under low nitrogen (N) input than under high N input. The long-term yield-increasing effect of biochar was more attributable to its enhancement of SOC rather than its effects on soil bulk density and pH.

施用生物炭对作物产量的影响一直是人们关注的话题。然而,目前大多数研究都集中在生物碳对作物生长的短期影响上。研究生物炭对提高作物产量的长期影响对于粮食安全和农业可持续发展至关重要。为解决这一问题,本研究在建立包含 981 组观测数据的数据集的基础上,对元分析和结构方程模型(SEM)进行了耦合。结果表明,生物炭显著而持久地提高了作物产量,在超过 2 年的监测期内,生物炭还显示 SOC 平均增加了 36.2%。长期施用生物炭后,作物产量平均提高了 16%,但不同作物类型的增产幅度不同,施用生物炭对玉米和小麦的增产效果优于水稻。值得注意的是,施用生物炭 6 年后,平均产量仍增加了 15%。根据 SEM 的研究,增产效果与生物炭的施用量呈正相关,低氮投入下的增产效果高于高氮投入下的增产效果。生物炭的长期增产效果更多归因于其对 SOC 的增强,而不是对土壤容重和 pH 值的影响。

The overconsumption of conventional plastics has led to several environmental and social-economic issues related to plastic pollution, carbon emissions and resource depletion. Acknowledging these issues, the introduction of alternatives such as bioplastics has been promoted by national, supranational, and international organizations. However, the market for such materials is still niche, where businesses are uncertain about the benefits and costs associated with the use of these innovative materials. Successful (and sustainable) uptake of such alternatives will depend on public acceptance and changes in consumer behavior. Therefore, this study aims to explore how consumers' orientation towards environmental sustainability is related to consumer utilization of alternatives such as bio-based and biodegradable plastics. Consumer knowledge and performance expectations of these materials are also analyzed. This study employed a predominately quantitative research approach, where a self-administered online survey was used to collect the opinions of consumers across society using a snowball sampling technique. Results show continued consumer confusion, unrealistic expectations, and a value-action gap. These elements may have consequences for market uptake and broader implications across the value chain. A key implication is that both policy makers and businesses should address these barriers through enhanced communication of relevant information alongside improved consumer awareness and education.

传统塑料的过度消费导致了一些与塑料污染、碳排放和资源枯竭有关的环境和社会经济问题。认识到这些问题后,国家、超国家和国际组织开始推广生物塑料等替代品。然而,这类材料的市场仍然很小,企业对使用这些创新材料的相关效益和成本并不确定。能否成功(和可持续)采用这些替代品将取决于公众的接受程度和消费者行为的改变。因此,本研究旨在探讨消费者对环境可持续性的取向与消费者使用生物基塑料和生物降解塑料等替代品之间的关系。此外,还分析了消费者对这些材料的认知和性能期望。本研究主要采用定量研究方法,通过自设在线调查,采用滚雪球抽样技术收集全社会消费者的意见。调查结果显示,消费者仍然存在困惑、不切实际的期望以及价值与行动之间的差距。这些因素可能会影响市场吸收,并对整个价值链产生更广泛的影响。一个重要的影响是,政策制定者和企业都应通过加强相关信息的沟通,同时提高消费者的意识和教育,来解决这些障碍。

Challenges to managing fisheries with high inter-community variability on the Kenya-Tanzania border 管理肯尼亚-坦桑尼亚边境社区间差异较大的渔业所面临的挑战

Reconciling variable between-community and neighboring country goals is the focus of the United Nations partnership goals (Sustainable Development Goal 17) because of the challenges of managing shared common-pool resources, such as fisheries. Our objective was to better understand and suggest management that accounts for this variability among fishing villages along the Kenya-Tanzania national boundary. We asked stakeholders to scale their dependency on fish, objective knowledge of fisheries, governance effectiveness, management preferences, and future fisheries provisioning scenarios among villages economically aligned with international trade or national park conservation. We found high dependency on fish (90% daily consumption), modest objective knowledge about fisheries and their status (62% correct answers) but a broad agreement on the need for community engagement (>90% agreement). The perceived weakest governance principles were fisheries monitoring and the resolution of conflicts with neighbors. Considerable variability in opinions about how to provide more fish reflected the international boundary trade and conservation contexts. Rural households further from the border favored community management and local or national fisheries closure management whereas stakeholder preferences with more urban and public were associated with greater support for offshore fishing and port and aquaculture infrastructure developments. Previously measured losses of fisheries catch production in most villages was hidden from stakeholders by a lack of catch monitoring and production potential estimates. Lost fisheries production and sustainability could be recovered by increased knowledge of resource production capacity, monitoring, and governance engagement that increases compliance. Village level economics and transnational contexts require multilevel governance and good coordination to manage the diverse capacities, preferences, and management needs.

由于渔业等共有资源的管理面临挑战,协调社区间和邻国间的可变目标是联合国伙伴关系目标(可持续发展目标 17)的重点。我们的目标是更好地理解肯尼亚-坦桑尼亚国界沿线渔村之间的这种可变性,并提出相应的管理建议。我们要求利益相关者衡量他们对鱼类的依赖程度、对渔业的客观认识、治理效果、管理偏好,以及与国际贸易或国家公园保护在经济上保持一致的村庄未来的渔业供应情况。我们发现,人们对鱼类的依赖程度很高(90% 的人每天食用鱼类),对渔业及其现状的客观了解不多(62% 的人回答正确),但对社区参与的必要性却有广泛共识(90% 的人同意)。认为最薄弱的管理原则是渔业监测和解决与邻居的冲突。关于如何提供更多鱼类的意见存在很大差异,这反映了国际边界贸易和保护背景。离边境较远的农村家庭倾向于社区管理和地方或国家渔业关闭管理,而更多城市和公共利益相关者的偏好则与更多支持近海捕捞以及港口和水产养殖基础设施发展有关。由于缺乏渔获量监测和生产潜力估算,利益相关者无法获知大多数村庄先前测算的渔业产量损失。可以通过增加对资源生产能力的了解、监测以及提高合规性的治理参与来挽回渔业产量和可持续性的损失。村级经济和跨国环境需要多级治理和良好协调,以管理不同的能力、偏好和管理需求。
