Can climate accords based on decentralized and voluntary agreements successfully reduce carbon emissions? We designed an economic experiment to study the effectiveness of the best-known mechanisms to foster international cooperation on climate change mitigation: climate pledges, financial penalties, and peer evaluation. We test each mechanism both separately and together. In the climate pledge treatments, participants could pledge their desired emissions target, approved by majority vote. In the treatments with financial penalties, failure to meet pledges triggered monetary sanctions. In the peer evaluation treatments, participants could evaluate each other, which determined who would receive an additional nonmonetary environmental prize. We find that most participants joined climate agreements and met their pledges, but pledges were insufficiently ambitious. As a result, neither pledges, financial penalties, nor peer evaluation reduced emissions. These results question the effectiveness of decentralized and voluntary climate agreements, such as the Paris Agreement.
基于分散和自愿协议的气候协议能否成功减少碳排放?我们设计了一个经济实验来研究最著名的促进减缓气候变化国际合作机制的有效性:气候承诺、经济惩罚和同行评价。我们对每种机制进行了单独和共同测试。在气候承诺处理中,参与者可以承诺他们希望达到的排放目标,并由多数票通过。在有经济处罚的处理中,未履行承诺将受到经济处罚。在同伴评价处理中,参与者可以相互评价,从而决定谁将获得额外的非货币环境奖。我们发现,大多数参与者都加入了气候协议并履行了承诺,但承诺的目标不够远大。因此,无论是承诺、经济处罚还是同行评价都没有减少排放量。这些结果对《巴黎协定》等分散式自愿气候协议的有效性提出了质疑。

In recent years, China has pivoted towards a global leadership role in mitigating and adapting to climate change. Notwithstanding the complex political economic reasons underlying China's global leadership aspirations, we are interested in seeing whether the associated national discourse championed by the state increases domestic support for climate policy. That is, do China's international leadership aspirations foster a unifying sense of national pride among the domestic population, thereby lending support to the legitimacy of the state and expediting the implementation of costly domestic climate policies? To test our hypothesis, we enumerated a vignette experiment embedded with conjoint analysis to a nationally representative sample (n = 4788). We found no evidence that exposure to China's global leadership aspirations increased domestic support for national-level climate policy, as proxied by a carbon tax. Indeed, we found that exposure to China's global climate leadership aspirations decreased domestic support for a carbon tax under certain scenarios. Our findings demonstrate a potential disconnect between global and local climate policy discourses and suggest that China's policymakers need to exercise caution in ensuring that their global climate leadership aspirations do not come at the expense of decreased domestic support for the national-level policies required to meet China's goal of carbon neutrality by 2060.
近年来,中国已转向在减缓和适应气候变化方面发挥全球领导作用。尽管中国的全球领导抱负背后有着复杂的政治经济原因,但我们仍有兴趣了解国家倡导的相关国家话语是否会增加国内对气候政策的支持。也就是说,中国的国际领导抱负是否会在国内民众中形成一种统一的民族自豪感,从而为国家的合法性提供支持,并加快实施成本高昂的国内气候政策?为了验证我们的假设,我们对一个具有全国代表性的样本(n = 4788)进行了嵌入联合分析的小故事实验。我们没有发现任何证据表明,接触中国的全球领导抱负会增加国内对国家级气候政策(以碳税为代表)的支持。事实上,我们发现,在某些情况下,接触中国的全球气候领导愿望会降低国内对碳税的支持。我们的研究结果表明全球和地方气候政策论述之间可能存在脱节,并建议中国的政策制定者需要谨慎行事,确保他们的全球气候领导愿望不会以减少国内对国家级政策的支持为代价,而国家级政策是实现中国 2060 年碳中和目标所必需的。

Increasing landfill and environmental costs are driving municipalities to search for effective policies to change household food waste disposal, balancing competing attributes such as effectiveness, fairness and feasibility. In order to better understand households' policy perspectives, we conducted an online survey with 1520 South Australians regarding four different food waste policies, namely: 1) frequency-based pricing for bin collection; 2) penalties for bin misuse; 3) changing bin collection timing; and 4) extension and education. A structural equation modelling approach was used to model overall policy preference, based on perceived policy attributes and household socio-demographics. Results highlighted that respondents' rated economic incentives (pricing and penalties) as the most effective in changing food waste behaviour, but rank these policies low in feasibility or acceptability. Conversely, education and information campaigns were rated as the lowest in effectively changing behaviour, but the most acceptable and fairest policy overall. Overall, respondents from households producing less food waste were more favourable towards introducing economic incentive food waste policies.
不断增加的垃圾填埋成本和环境成本促使市政当局寻找有效的政策来改变家庭食物垃圾的处理方式,同时兼顾有效性、公平性和可行性等相互竞争的属性。为了更好地了解家庭对政策的看法,我们对 1520 名南澳大利亚人就四种不同的食物垃圾政策进行了在线调查,这四种政策分别是1) 基于频率的垃圾桶收集定价;2) 垃圾桶滥用处罚;3) 改变垃圾桶收集时间;4) 推广和教育。根据感知到的政策属性和家庭社会人口特征,采用结构方程建模法对总体政策偏好进行建模。结果显示,受访者认为经济激励措施(定价和处罚)对改变食物浪费行为最有效,但这些政策的可行性和可接受性较低。相反,教育和宣传活动在有效改变行为方面被评为最低,但总体而言却是最可接受和最公平的政策。总体而言,来自食物浪费较少家庭的受访者更倾向于引入经济激励的食物浪费政策。

Building a local structural basis for economic change? A case study on grassroots initiatives from a ‘social provisioning’ perspective 为经济变革建立地方结构基础?从 "社会供应 "角度对基层倡议的案例研究

The ‘social provisioning process’ framework postulates that making provisioning processes more socially and ecologically sustainable requires structural changes in terms of the material, social, and cultural bases of economies. This paper explores the ways in which local community-led grassroots initiatives (GIs) contribute to such structural changes. The purpose of this paper is twofold: First, we offer systematic empirical evidence on the impact of GI activities on societal structures, which are crucial for assessing the transformative potential of GIs but have been insufficiently addressed in the literature. Second, we adapt and further develop the ‘social provisioning process’ framework to make it operational for research on local provisioning processes, thereby proposing a strong heterodox economic theory – which accounts for the structural dimension – to the research field of GIs that it was lacking so far. To this end, a qualitative multiple-case study design is employed to investigate three GIs. Eight categories of provisioning structures are identified as an advancement of the ‘social provisioning process’ framework. The data show how the three GI cases build a structural basis in each of the eight categories, which tends to facilitate more sustainable provisioning, and reveal foci, strategies, and limitations in the creation of those structures.
社会供应过程 "框架假定,要使供应过程在社会和生态方面更具可持续性,就必须在经济的物质、社会和文化基础方面进行结构性变革。本文探讨了地方社区主导的基层倡议(GIs)如何促进这种结构性变化。本文有两个目的:首先,我们提供了有关基层倡议活动对社会结构影响的系统性经验证据,这些证据对于评估基层倡议的变革潜力至关重要,但在文献中却没有得到充分论述。其次,我们调整并进一步发展了 "社会供应过程 "框架,使其在地方供应过程研究中具有可操作性,从而为地理标志产品研究领域提出了迄今为止所缺乏的强有力的异端经济理论--该理论考虑到了结构层面。为此,我们采用了定性多案例研究设计来调查三个地理标志产品。作为 "社会供应过程 "框架的推进,确定了八类供应结构。数据显示了三个地理信息系统案例如何在八个类别中的每一个类别中建立结构基础,从而促进更可持续的供应,并揭示了建立这些结构的重点、策略和局限性。

This paper introduces an analytical model that characterizes the incentives of the manufacturing industry, consumers, and waste management sectors in closing the material loop. To address identified market failures, various policy instruments are evaluated both theoretically and numerically, using the example of the EU PET market. The assessment shows that a policy package consisting of carbon pricing, advanced disposal fees, and product standards substantially reduces total material consumption and enhances material recovery, leading to a notable reduction in emissions. The analysis of material cost savings, surplus allocation, and social welfare also shows the advantages of such a policy package compared to individual policy instruments.
本文介绍了一个分析模型,该模型描述了制造业、消费者和废物管理部门在闭合材料循环过程中的激励机制。为解决已发现的市场失灵问题,本文以欧盟 PET 市场为例,对各种政策工具进行了理论和数值评估。评估结果表明,由碳定价、高级处置费和产品标准组成的一揽子政策大幅降低了材料总消耗量,提高了材料回收率,从而显著减少了排放量。对材料成本节约、剩余分配和社会福利的分析也表明,与单个政策工具相比,这种一揽子政策具有优势。

Seagrass habitats are essential and vulnerable ecosystems with several key roles, from biodiversity hotspots to climate change mitigation. Their characteristics, current condition and potential benefits, are the main core of this study which presents one of the first applications of marine accounts for the European Mediterranean Sea. The assessment focuses on four marine and coastal ecosystem services (i.e. fish and raw biomass provision, blue carbon, and nature-based recreation) and relies on habitat modelling for the biophysical assessment and a diversity of economic valuation tools (e.g. resource rent, avoided costs, benefit transfer) for the monetization of benefits. The findings highlight the essential benefits provided by seagrass meadows for Mediterranean European countries. Accounting tables display the role of seagrass to enhance environmental and economic well-being and the support that accounting evidence can provide for conservation, restoration and marine spatial planning.
海草栖息地是重要而脆弱的生态系统,具有从生物多样性热点到减缓气候变化等多个关键作用。它们的特征、当前状况和潜在效益是本研究的主要核心,也是欧洲地中海海洋账户的首次应用之一。评估重点是四种海洋和沿海生态系统服务(即鱼类和生物质原料供应、蓝碳和自然娱乐),并依靠生境建模进行生物物理评估和多种经济估值工具(如资源租金、避免的成本、效益转移)进行效益货币化。研究结果凸显了海草草甸为地中海欧洲国家带来的重要效益。核算表显示了海草在提高环境和经济福祉方面的作用,以及核算证据可为保护、恢复和海洋空间规划提供的支持。

Green coops: Drivers of innovation for circular strategies among Italian cooperatives 绿色合作社:意大利合作社循环战略创新的驱动力

The distinct characteristics of cooperatives, grounded in values such as self-help, selfresponsibility, etc. (ICA) make them a distinctive form of enterprise that necessitates examination. As other forms of enterprise, cooperatives bear the same onus of ensuring sustainability. To comprehend the social and economic contribution of cooperatives, we investigate their impact and role in attaining environmental sustainability, focusing on circular strategies. Preliminary literature in EI finds that cooperatives facilitate the implementation of some circular economy (CE) processes with general cooperation as an EI driver. After reviewing the literature on the drivers behind the introduction of EI in SMEs, we sought to investigate the specific drivers for cooperatives. To do this, we employed an econometric model to examine CES behaviour in a sample of over 280 Italian cooperatives across various regions and sectors in Italy. The findings underscore the role of cooperation and key managerial factors as drivers for implementation of circular economy innovative strategies. While innovation drivers have been researched for SMEs, the absence on research focusing on the cooperative model, makes this paper strongly relevant to investigate how a specific firms structure would lead to their transition to be a circular innovative cooperative or rather “green” cooperative.
合作社以自助、自我负责等价值观为基础,具有鲜明的特点(国际合作社联盟),使其成为一种独特的企业形式,有必要对其进行研究。与其他形式的企业一样,合作社同样肩负着确保可持续发展的重任。为了理解合作社的社会和经济贡献,我们调查了它们在实现环境可持续性方面的影响和作用,重点是循环战略。环境创新方面的初步文献发现,合作社促进了一些循环经济(CE)进程的实施,而一般合作是环境创新的驱动力。在回顾了有关中小企业引入环境创新背后驱动因素的文献后,我们试图调查合作社的具体驱动因素。为此,我们采用计量经济学模型,对意大利不同地区和行业的 280 多家合作社的 CES 行为进行了抽样调查。研究结果强调了合作和关键管理因素对实施循环经济创新战略的推动作用。虽然已经对中小企业的创新驱动力进行了研究,但缺乏针对合作社模式的研究,这使得本文与研究特定企业结构如何促使其转型为循环创新合作社或 "绿色 "合作社密切相关。

This article aims to advance understandings of food systems functioning at a national level and explore ways for its transformation towards sustainability and social justice. Integrating food regime theory from political economy with social metabolism from ecological economics, and surplus/reproduction from feminist economics, we develop a novel research framework which combines six dimensions—food systems governance, monetary agrifood chain, socio-metabolic agrifood chain, surplus/reproduction, socioecological impacts, and conflicts & levers of change—encompassing 34 elements linked through six key connections. The research framework highlights the role of cheap food for the social reproduction of the labouring population in capitalism. Since national states play important roles in maintaining food regimes, we conducted a critical literature review through which we identified the main contributions and limitations of studies of food regimes at the national level aimed at foreseeing exit ways beyond the current corporate food regime. This regime is one of the main drives of the overcoming of planetary boundaries. An agroecological transition and food system change is needed to address this socio-ecological crisis, and this requires new food polices at a national level as well. This is why we consider it essential to integrate social metabolism with the approaches of food regimes and surplus/reproduction.
本文旨在推进对国家层面粮食系统运作的理解,并探索其向可持续发展和社会公正转变的途径。我们将政治经济学中的粮食制度理论与生态经济学中的社会新陈代谢理论以及女权主义经济学中的剩余/再生产理论相结合,建立了一个新颖的研究框架,该框架结合了六个维度--粮食系统治理、货币农业粮食链、社会新陈代谢农业粮食链、剩余/再生产、社会生态影响以及冲突&;变革杠杆--包含 34 个要素,通过六种关键联系相互关联。研究框架强调了廉价粮食对资本主义劳动人口社会再生产的作用。由于国家在维持粮食体制方面发挥着重要作用,我们进行了一次批判性文献回顾,通过回顾,我们确定了国家层面粮食体制研究的主要贡献和局限性,旨在预见超越当前企业粮食体制的出路。这种制度是克服地球边界的主要动力之一。为解决这一社会生态危机,需要进行农业生态转型和粮食系统变革,这也需要在国家层面制定新的粮食政策。因此,我们认为必须将社会新陈代谢与粮食制度和剩余/生产方法结合起来。

This regime is one of the main drives of the overcoming of planetary boundaries. An agroecological transition and food system change is needed to address this socio-ecological crisis, and this requires new food polices at a national level as well. This is why we consider it essential to integrate social metabolism with the approaches of food regimes and surplus/reproduction.</div></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":"227 ","pages":"Article 108428"},"PeriodicalIF":6.6,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142528940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The confluence of multiple crises has prompted a growing recognition of the need for transformations. Economic systems, including patterns of consumption and production, play a key role in sustainability transformations. The notion that capitalist systems are at the root of current ecological and social crises has led to the emergence of different alternative economic discourses, that seek to address the indirect drivers of unsustainability. In this article, we aim to contribute to moving the debate beyond critiques of capitalism by focussing on the paths of transformation towards alternatives. To this end, we analyse several alternative economic discourses in order to show the breadth of the debate, and to better understand the roles and strategies of various discourses in societal transformation. Seven discourses are included, of which Buen Vivir, Degrowth and Wellbeing Economy are analysed in-depth. This is done through a systematic analysis of literature published between 2015 and 2022, using an enhanced conceptual framework based on the works of Wright (2019) and Chertkovskaya (2022). Our analysis suggests that the discourses represent different modes of transformation, and that these differences exist both between, as well as within the different discourses. We argue that transformations cannot be achieved through single discourses, or modes of transformation. Rather, concerted efforts of different discourses aimed at addressing indirect drivers of unsustainability can provide the multi-faceted processes of societal change, in which they can support and reinforce one another through alliances and mutual learning.
多重危机交织在一起,促使人们日益认识到转型的必要性。经济体系,包括消费和生产模式,在可持续性转型中发挥着关键作用。资本主义制度是当前生态和社会危机的根源,这一观点导致了不同的替代经济论述的出现,这些论述寻求解决不可持续的间接驱动因素。在这篇文章中,我们的目标是通过关注向替代方案转型的途径,推动辩论超越对资本主义的批判。为此,我们分析了几种替代性经济论述,以展示辩论的广度,并更好地理解各种论述在社会转型中的作用和策略。我们对其中的 "美好生活"(Buen Vivir)、"去增长"(Degrowth)和 "福祉经济"(Wellbeing Economy)进行了深入分析。分析是通过对 2015 年至 2022 年间发表的文献进行系统分析完成的,并使用了基于赖特(2019 年)和切尔特科夫斯卡娅(2022 年)著作的增强概念框架。我们的分析表明,这些论述代表了不同的转型模式,这些差异既存在于不同论述之间,也存在于不同论述内部。我们认为,转型不能通过单一的话语或转型模式来实现。相反,旨在解决不可持续性间接驱动因素的不同论述之间的协同努力可以提供多方面的社会变革过程,在这一过程中,它们可以通过联盟和相互学习来相互支持和加强。

Efficiency, sufficiency and consistency in sustainable development: Reassessing strategies for reaching overarching goals 可持续发展的效率、充足性和一致性:重新评估实现总体目标的战略

Humanity faces a dilemma: The satisfaction of human needs gravely endangers the natural basis of life. As potential strategies for resolving this dilemma, we revisit the discourse on efficiency, sufficiency and consistency. Although there has been much discussion about the three strategies in recent decades, there is a lack of a clear distinction between the strategies and little understanding regarding their respective impact on both the environment and human needs satisfaction. This leads to persistent disagreement about which strategies are best suited to pursue in the short, medium and long term. In this article, we resolve this problem on a conceptual level through a graphical classification of the three strategies according to their effects on consumption levels and environmental impact. This framework contributes to the literature on energy transition and the circular economy as key paths to sustainability by showing the limited effects of efficiency and sufficiency strategies over the long run in contrast to the promise of the consistency strategy as a systemic change.
人类面临着两难境地:满足人类的需求严重危及生命的自然基础。作为解决这一困境的潜在策略,我们重温了关于效率、充足性和一致性的论述。尽管近几十年来关于这三种战略的讨论不绝于耳,但这三种战略之间缺乏明确的区别,人们对它们各自对环境和满足人类需求的影响也知之甚少。这导致人们对短期、中期和长期最适合采取哪种战略始终存在分歧。在本文中,我们根据三种战略对消费水平和环境影响的影响,以图表形式对其进行了分类,从而在概念层面上解决了这一问题。这一框架表明,效率和充足战略的长期效果有限,而一致性战略则有望带来系统性变革,从而为有关能源转型和循环经济的文献做出了贡献。
