Copper is essential for modern economies including: energy systems, data centers, defense applications, space cooling and heating, heavy industry, smart agriculture, transportation, and consumer goods. The presumption persists that the copper needed for all these purposes will be readily available. However, we show that copper is unlikely to be mined fast enough to meet all these needs in the short to medium term. Despite the recent and rapid copper price rise, we suggest that it will have to continue to rise significantly and provide robust price signals for a significant number of known copper deposits to be developed into mines. This price signal will need to be associated with permitting reforms to be successful in several cases. The widening gap should be a matter of political prioritization both in the USA and globally.
铜对现代经济至关重要,包括:能源系统、数据中心、国防应用、空间制冷和供暖、重工业、智能农业、交通运输和消费品。这种假设坚持认为,所有这些用途所需的铜都很容易获得。然而,我们表明,铜的开采速度不太可能快到足以在中短期内满足所有这些需求。尽管最近铜价快速上涨,但我们认为,铜价必须继续大幅上涨,并为大量已知铜矿开发成矿山提供强有力的价格信号。在一些情况下,这种价格信号需要与允许改革取得成功联系起来。不断扩大的差距应该成为美国和全球政治优先考虑的问题。

There is an urgent need for scalable interventions that can shift societal norms and human behaviour to address the global sustainability crisis. With its extensive reach and cultural influence, mass media is a critical yet underutilised tool in this effort. This paper presents a novel, real-world study to explore the effectiveness of promoting residential energy efficiency through a reality-style television show. Behavioural science principles were embedded throughout the 8-part television series, with a longitudinal mixed-method design used to evaluate the potential impact on viewers over time. Statistical analysis of the results suggested that watching the show was positively associated with an increase in viewers' self-reported desire for homes with an energy star rating above the minimum standard, with this effect strengthening based on the amount of content viewed. Qualitative insights from semi-structured focus group discussions also supported this potential positive influence of the TV series. Overall, this study demonstrates a practical, real-world example of how combining behavioural science with entertainment and mass media can support behaviour change, while also providing a framework to inform the design of future interventions to promote sustainable behaviours at scale.
迫切需要采取可扩展的干预措施,改变社会规范和人类行为,以应对全球可持续性危机。由于其广泛的影响和文化影响,大众传媒是这一努力中一个关键但未得到充分利用的工具。本文提出了一项新颖的、现实世界的研究,通过真人秀式的电视节目来探索促进住宅能源效率的有效性。行为科学原理贯穿于这部8集的电视剧中,并采用纵向混合方法设计来评估随着时间的推移对观众的潜在影响。对结果的统计分析表明,观看该节目与观众自我报告的对能源之星评级高于最低标准的房屋的渴望的增加呈正相关,这种影响随着观看内容的数量而增强。从半结构化焦点小组讨论中获得的定性见解也支持了这部电视剧潜在的积极影响。总的来说,这项研究展示了一个实际的,现实世界的例子,如何将行为科学与娱乐和大众媒体结合起来,支持行为改变,同时也提供了一个框架,为未来干预措施的设计提供信息,以促进大规模的可持续行为。

No empty land: Comparing distributional outcomes of solar parks across land tenure regimes in India 没有空地:比较印度不同土地权属制度下太阳能公园的分配结果

Large-scale solar park development has accelerated in India over the last decade, with multiple 500 MW+ parks being built as part of the country's effort to decarbonise its electricity system. These projects require thousands of acres of contiguous land. However, land is a socially embedded resource with no ‘empty’ land available that does not already serve some purpose. Drawing on field research and qualitative interviews across three sites—Bhadla and Fatehgarh in Rajasthan, and Pavagada in Karnataka—we analyse the distributional injustices that accompany large-scale solar park development. We compare two land tenure arrangements: private agricultural land and government-owned land that local communities use for farming and grazing. Using the social-ecological systems framework, we conceptualise these tenure arrangements in terms of inequalities in land ownership, the importance of the resource to different socio-economic groups, and the property regimes under which solar parks are developed. We find, first, that ownership of private agricultural land in Karnataka enables farmers to claim monetary compensation. This is in contrast with solar parks in Rajasthan, where the absence of land-use records and formal titles prevents some farmers and agropastoral groups from accessing any monetary benefits. Second, agropastoral groups and landless households—often from marginalised caste groups—are disadvantaged across all cases, as they lose access to common property resources for livestock rearing as well as to private farmland for wage labour. These findings highlight how diverse land tenure systems shape, and often deepen, unequal distributional outcomes from India's solar transition.
在过去十年中,印度的大型太阳能园区开发速度加快,作为该国电力系统脱碳努力的一部分,印度正在建设多个500兆瓦以上的园区。这些工程需要数千英亩的连片土地。然而,土地是一种社会资源,没有“空”的土地可用,没有一些目的。通过实地调研和三个地点的定性访谈——拉贾斯坦邦的巴德拉和法特加尔,卡纳塔克邦的帕瓦加达——我们分析了伴随着大规模太阳能园区发展的分配不公正。我们比较了两种土地使用权安排:私人农业用地和当地社区用于耕作和放牧的政府所有土地。利用社会生态系统框架,我们从土地所有权的不平等、资源对不同社会经济群体的重要性以及太阳能公园开发的财产制度等方面对这些权属安排进行了概念化。我们发现,首先,卡纳塔克邦私有农业用地的所有权使农民能够要求货币补偿。这与拉贾斯坦邦的太阳能公园形成鲜明对比,在拉贾斯坦邦,由于缺乏土地使用记录和正式所有权,一些农民和农牧团体无法获得任何经济利益。其次,农牧群体和无地家庭——通常来自被边缘化的种姓群体——在所有情况下都处于不利地位,因为他们无法获得饲养牲畜的公共财产资源,也无法获得从事雇佣劳动的私人农田。这些发现强调了不同的土地权属制度如何塑造并经常加深了印度太阳能转型带来的不平等分配结果。

This study examines patterns of adoption and outcomes associated with Community Choice Aggregations (CCAs) in the San Francisco Bay Area and focuses on how customer participation and electricity rates are correlated to race and income. CCAs are often promoted as tools for advancing clean energy access, yet limited research has examined whether participation and rate outcomes vary across socioeconomic contexts. Using a mixed-methods approach, the study combines bivariate correlation and regression analysis with qualitative insights from interviews with six industry professionals representing CCAs, the local investor-owned utility (PG&E), and a regional trade association (CalCCA). The results suggest that CCAs generally provided higher renewable energy content at lower electricity rates than the investor-owned utility, particularly at the baseline 50% renewable energy tier. At the 100% renewable energy tier, total electricity rates were typically modestly higher. Customer participation rates were positively associated with both racial diversity and median household income, although interview participants emphasized that variation in customer awareness, trust, and understanding of CCAs also shapes decisions to opt-out from CCA enrollment. Overall, the findings show no evidence to suggest that automatic CCA enrollment at the 50% renewable energy tier systematically disadvantaged historically marginalized groups based on race or income. Instead, the results suggest broadly equitable access to more renewable electricity across the region and highlight the importance of public education, community engagement, and institutional trust in sustaining participation and supporting an inclusive clean energy transition.
本研究考察了旧金山湾区社区选择聚合(CCAs)的采用模式和结果,并重点研究了客户参与和电价与种族和收入之间的关系。cca经常被宣传为促进清洁能源获取的工具,然而,关于参与和费率结果是否因社会经济背景而不同的研究有限。该研究采用混合方法,将双变量相关和回归分析与来自六位行业专业人士的访谈相结合,这些专业人士分别代表cca、当地投资者拥有的公用事业公司(PG&;E)和区域贸易协会(CalCCA)。结果表明,cca通常比投资者拥有的公用事业公司以更低的电价提供更高的可再生能源含量,特别是在基线50%的可再生能源层。在100%可再生能源层,总电价通常略高。客户参与率与种族多样性和家庭收入中位数呈正相关,尽管访谈参与者强调,客户对CCA的认识、信任和理解的变化也影响了他们选择退出CCA的决定。总体而言,研究结果表明,没有证据表明50%可再生能源层的自动CCA注册系统地使历史上基于种族或收入的边缘化群体处于不利地位。相反,研究结果表明,整个地区可以广泛公平地获得更多的可再生电力,并强调了公共教育、社区参与和机构信任对维持参与和支持包容性清洁能源转型的重要性。

Comparing two court rulings on Shell's carbon emissions with climate-policy science 比较两个法院对壳牌公司碳排放的裁决与气候政策科学

In November 2024, a ruling by a Dutch Court of Appeal overturned a 2021 District Court verdict concerning the obligations of the oil and gas company Shell to reduce its carbon emissions. This perspective article examines the scientific basis of the differing arguments in the two court rulings, with a particular focus on the effectiveness of emissions-reduction strategies. To this end, we first summarize the reasoning in both rulings and identify their key points of divergence. Subsequently, we assess which ruling aligns more closely with the scientific literature on climate policy. Our analysis zooms in on four issues: the public-good nature of climate mitigation and the problem of free-riding; the aim and impact of the European Union's Emissions Trading System; the treatment of Scope 3 emissions generated by end users of Shell's products; and the roles of companies versus the state in achieving emissions reductions. We conclude that the Court of Appeal's ruling is more consistent with current scientific insights about effective climate policy than the earlier District Court decision. This is not to deny that companies like Shell will have to fundamentally transform – or otherwise eventually disappear – on the path to a zero‑carbon economy. But such change is most likely to occur as the outcome of a systemic policy approach that delivers steady and substantial emissions reductions across all sectors and jurisdictions. We therefore argue that a more effective legal strategy is to pursue legal action against governments that fail to implement policies in line with internationally agreed climate targets.
2024年11月,荷兰上诉法院的一项裁决推翻了2021年地区法院关于壳牌石油天然气公司减少碳排放义务的判决。这篇观点文章考察了两项法院裁决中不同论点的科学依据,特别关注减排战略的有效性。为此,我们首先总结了两项裁决的理由,并确定了它们的主要分歧点。随后,我们评估哪项裁决更符合气候政策的科学文献。我们的分析集中在四个问题上:减缓气候变化的公益性质和搭便车的问题;欧盟排放交易体系的目标和影响;处理壳牌产品最终用户产生的第3类排放;以及企业与国家在实现减排方面的作用。我们的结论是,上诉法院的裁决比地区法院早先的裁决更符合当前关于有效气候政策的科学见解。这并不是否认像壳牌这样的公司将不得不从根本上转型——或者最终消失——在通往零碳经济的道路上。但是,这种变化最有可能是系统性政策方法的结果,这种政策方法可以在所有部门和司法管辖区实现稳定和实质性的减排。因此,我们认为,更有效的法律策略是对那些未能按照国际商定的气候目标执行政策的政府采取法律行动。

The global low-carbon energy transition affects different country groups unevenly, creating significant opportunities for some and exposing others to risks. To capture this asymmetry, we develop an index of readiness to energy transition (RET index) that ranks 133 countries according to their potential gains and losses. The index includes two dimensions: transition assets, which are exposed positively, i.e., clean energy potential, abundance in critical metals and minerals, and negatively, namely dependence on fossil fuels and fossil fuel intensive industries, carbon intensity of economies, as well as adaptation potential. The resulting ranking of countries provides useful insights into countries' standing in low-carbon energy transition. Most of developed countries gain from high adaptation potential and limited carbon-intensive transition assets, making them resilient to low-carbon transformation. China occupies a unique position, benefiting from strong clean energy potential and dominance in the global critical materials landscape. On the contrary, many emerging and developing economies face high transition risks due to fossil fuel dependency, high overall carbon intensity and relatively weak technological and institutional capacities. The RET index thus highlights these asymmetries, emphasizing the importance of targeted international support and differentiating mitigation ambition levels under just energy transition framework.
全球低碳能源转型对不同国家群体的影响不均衡,为一些国家创造了重大机遇,而使另一些国家面临风险。为了捕捉这种不对称性,我们制定了能源转型准备指数(RET指数),根据其潜在收益和损失对133个国家进行排名。该指数包括两个维度:转型资产,正向暴露,即清洁能源潜力,关键金属和矿物的丰度;负向暴露,即对化石燃料和化石燃料密集型产业的依赖,经济体的碳强度,以及适应潜力。由此得出的国家排名为各国在低碳能源转型方面的地位提供了有用的见解。大多数发达国家受益于高适应潜力和有限的碳密集型转型资产,使它们能够适应低碳转型。中国占据着独特的地位,受益于强大的清洁能源潜力和全球关键材料格局的主导地位。相反,由于依赖化石燃料、总体碳强度高、技术和制度能力相对薄弱,许多新兴和发展中经济体面临较高的转型风险。因此,RET指数突出了这些不对称,强调了有针对性的国际支持和在公正的能源转型框架下区分减缓目标水平的重要性。

From context to operationalization: Exploring chances for the integration of social scientific perspectives in life cycle assessments of energy technologies 从背景到操作:探索将社会科学观点纳入能源技术生命周期评估的机会

The life cycle assessment (LCA) methodology is a well-established tool to assess the environmental impacts of products, services, and technologies. Despite of its standardization, the methodology lacks guidance and formalization for the consideration of behavioral effects impacting the energy consumption related to the usage of technologies. As digital and smart technologies are supposed to play a major role in the energy transition, a consideration of these effects is crucial for the comprehensive assessment of environmental impacts caused by these technologies. In order to address the lack of formalized approaches for the integration of behavioral effects into LCA studies, a qualitative interview study with experts from the social sciences and LCA practice was set up, identifying challenges and chances for the interdisciplinary alignment of the LCA methodology with social scientific approaches. On the basis of the content analysis, the study highlights barriers for the transfer of knowledge between the disciplines and offers insights on challenges faced by practitioners (e.g. lack of time and financing resources or skepticism experienced by peers). Social scientific perspectives and recommendations expressed by the researchers were aligned with the standardized steps of an LCA, providing insights on possible contributions of the social scientific methods to a more comprehensive assessment of environmental impacts caused by energy-using technologies. The interdisciplinary study thereby connects methodological and empirical insights from research practice, enabling the understanding of socio-technical and socio-environmental dependencies in order to assess environmental impacts of energy using technologies in a comprehensive way.
生命周期评估(LCA)方法是一种完善的工具,用于评估产品、服务和技术对环境的影响。尽管其标准化,但该方法缺乏对影响与技术使用有关的能源消耗的行为影响的考虑的指导和形式化。由于数字和智能技术应该在能源转型中发挥重要作用,因此考虑这些影响对于全面评估这些技术造成的环境影响至关重要。为了解决将行为效应整合到LCA研究中缺乏形式化方法的问题,我们对来自社会科学和LCA实践的专家进行了定性访谈研究,确定了LCA方法论与社会科学方法跨学科结合的挑战和机遇。在内容分析的基础上,该研究强调了学科之间知识转移的障碍,并对从业者面临的挑战(例如缺乏时间和资金资源或同行的怀疑)提供了见解。研究人员提出的社会科学观点和建议与LCA的标准化步骤相一致,为更全面地评估能源利用技术造成的环境影响提供了社会科学方法的可能贡献。因此,跨学科研究将研究实践的方法和经验见解联系起来,使人们能够理解社会技术和社会环境的依赖关系,以便全面评估能源使用技术对环境的影响。

In order to address the lack of formalized approaches for the integration of behavioral effects into LCA studies, a qualitative interview study with experts from the social sciences and LCA practice was set up, identifying challenges and chances for the interdisciplinary alignment of the LCA methodology with social scientific approaches. On the basis of the content analysis, the study highlights barriers for the transfer of knowledge between the disciplines and offers insights on challenges faced by practitioners (e.g. lack of time and financing resources or skepticism experienced by peers). Social scientific perspectives and recommendations expressed by the researchers were aligned with the standardized steps of an LCA, providing insights on possible contributions of the social scientific methods to a more comprehensive assessment of environmental impacts caused by energy-using technologies. The interdisciplinary study thereby connects methodological and empirical insights from research practice, enabling the understanding of socio-technical and socio-environmental dependencies in order to assess environmental impacts of energy using technologies in a comprehensive way.</div></div>","PeriodicalId":48384,"journal":{"name":"Energy Research & Social Science","volume":"132 ","pages":"Article 104558"},"PeriodicalIF":7.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146078828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding how multiple socio-technical systems transform in tandem has become an important frontier in sustainability transitions research. While the multi-level perspective has evolved into the multi-system perspective to conceptualise cross-system co-evolution, current studies largely overlook the relational micro-dynamics through which coordination and learning are enacted. To address this gap, this paper integrates experimental governance with the multi-system perspective to investigate how local experimentation can drive both single-system transitions and multi-system alignment. Drawing on policy analysis and 22 semi-structured interviews, we examine the Zhangjiakou wind-to-heat pilot in northern China, where wind power, district heating, electricity trading and emerging digital sectors became increasingly interconnected. Our analysis identifies a five-phase transition trajectory: dual-system coupling, incumbent system transition, emerging system reform, multi-system interaction, and diffusion effects. Our results show that experiments can become coordination infrastructures that temporarily bridge fragmented governance structures, enabling heterogeneous actors to build trust, co-produce knowledge, and adapt strategies through negotiation and iterative learning. These micro-level processes actively construct cross-system linkages, allowing local experiments to evolve into institutional arrangements that support regional low-carbon industrial diversification and economic upgrading. This study contributes to transition theory by grounding the micro-foundations of multi-system transitions and showing how experimentation can help overcome fragmented governance structures by enabling state-orchestrated coordination.
了解多个社会技术系统如何协同转变已成为可持续转型研究的重要前沿。虽然多层次视角已经演变为多系统视角来概念化跨系统协同进化,但目前的研究在很大程度上忽视了协调和学习的关系微观动力学。为了解决这一差距,本文将实验治理与多系统视角相结合,以研究本地实验如何驱动单系统转换和多系统对齐。通过政策分析和22个半结构化访谈,我们考察了中国北方张家口的风热试点,在那里,风力发电、区域供热、电力交易和新兴数字部门之间的联系日益紧密。我们的分析确定了五个阶段的过渡轨迹:双系统耦合、现有系统过渡、新兴系统改革、多系统互动和扩散效应。我们的研究结果表明,实验可以成为协调基础设施,暂时弥合碎片化的治理结构,使异质参与者能够建立信任,共同产生知识,并通过协商和迭代学习适应策略。这些微观层面的过程积极构建了跨系统的联系,使地方实验演变为支持区域低碳产业多元化和经济升级的制度安排。本研究通过奠定多系统转型的微观基础,并展示了实验如何通过实现国家协调来帮助克服分散的治理结构,从而为转型理论做出了贡献。

What does it mean to produce climate science in 2026? Building on the dialogical approach of Fenner and Harcourt [1], this paper explores how positionalities and emotional landscapes shape the work of three female researchers in climate science. Through a collective, reflexive dialogue, we confront the personal and structural tensions embedded in global climate science, examining power asymmetries, the tokenization of diversity, and the hegemonic dominance of quantification and masculinized norms. Our reflections draw attention to how scientific practices often, even unintentionally, perpetuate the very injustices they aim to address. These inherent exclusionary practices lead us to the idea of academia as a border. By weaving together anecdotal recollections and critical theory, we illuminate how situatedness matters, not just methodologically but politically. We critique the neoliberal and heteronormative underpinnings of academic institutions and propose a future-oriented agenda grounded in relationality, emotional honesty, and epistemic inclusivity. Our concluding recommendations aim to shift academic practice from extractive performance metrics to spaces of resistance, care, and collective transformation. As part of this, we bring a reflective tool inspired by Audre Lorde's [2] Questionnaire to Oneself to invite deeper engagement with the contradictions and silences within our own scholarly work.
在2026年产生气候科学意味着什么?本文以芬纳和哈考特的对话方法为基础,探讨了立场和情感景观如何塑造三位气候科学女性研究人员的工作。通过集体的反思性对话,我们面对全球气候科学中嵌入的个人和结构性紧张关系,审视权力不对称、多样性的标记化,以及量化和男性化规范的霸权统治。我们的反思引起了人们的注意,即科学实践往往(甚至是无意中)使它们旨在解决的不公正现象永久化。这些固有的排他性做法导致我们认为学术界是一个边界。通过将轶事回忆和批判理论编织在一起,我们阐明了情境性是如何重要的,不仅在方法上,而且在政治上。我们批判了学术机构的新自由主义和异性恋规范基础,并提出了一个基于关系、情感诚实和认知包容性的面向未来的议程。我们的结论性建议旨在将学术实践从抽取绩效指标转向抵抗、关怀和集体转型的空间。作为其中的一部分,我们带来了一个反思工具,灵感来自奥德丽·洛德的b[2]问卷给自己,邀请我们在自己的学术工作中更深入地参与矛盾和沉默。

Did firms accelerate decarbonization as a result of the 2015 Paris Agreement, particularly in industries where low-carbon options were technologically feasible? Paris marked a milestone in climate cooperation, but its effectiveness depends on the behavior of firms, which generate most global carbon emissions. Prior studies disagree on whether international agreements influence corporate action, and few analyze climate accords directly. This paper examines whether the Paris Agreement shifted corporate strategy in “convertible” industries, focusing on the automotive sector. Our analysis covers twelve global automakers, responsible for almost 80% of worldwide vehicle production, using six categories of primary evidence to assess strategic change. We find only limited evidence of decarbonization strategies tied to the Paris Agreement, suggesting that firm responses were at best incremental rather than transformative. These findings challenge optimistic accounts of the Paris Agreement's influence and call for continued efforts to understand the limits of international agreements in driving firm behavior to address climate change.
企业是否因为2015年的《巴黎协定》而加速脱碳,特别是在低碳选择在技术上可行的行业?巴黎协定标志着气候合作的一个里程碑,但其有效性取决于企业的行为,而企业是全球碳排放的主要来源。先前的研究在国际协议是否影响企业行为的问题上存在分歧,而且很少有研究直接分析气候协议。本文考察了《巴黎协定》是否改变了“可转换”行业的企业战略,重点是汽车行业。我们的分析涵盖了12家全球汽车制造商,占全球汽车产量的近80%,使用六类主要证据来评估战略变革。我们发现,只有有限的证据表明,与《巴黎协定》相关的脱碳战略,表明坚定的回应充其量是渐进式的,而不是变革性的。这些发现挑战了对《巴黎协定》影响的乐观描述,并呼吁继续努力了解国际协定在推动企业应对气候变化行为方面的局限性。
