Artificial Intelligence (AI) has emerged as a transformative technology with the potential to accelerate progress toward the United Nations' Sustainable Development Goals (SDGs). However, its adoption and societal implications vary significantly between developed and developing nations, shaped by differing priorities, socio-economic realities, and governance capacities. This study systematically analyzes global public discourse on AI and its alignment with the SDGs using natural language processing and a graph-based multi-label classification framework. By analyzing over 249,000 posts on social media (Twitter/X) and categorizing them into SDG-related concerns, we reveal shared global priorities, such as the emphasis on SDG 9 (Industry, Innovation, and Infrastructure), and key contextual divergences. Developed nations focus on optimizing advanced systems and ethical governance, while developing countries highlight AI's potential to bridge infrastructural gaps and promote digital equity. Notably, SDGs addressing essential human needs, such as Zero Hunger (SDG 2) and Clean Water and Sanitation (SDG 6), remain underrepresented globally. Using expert-driven Delphi panels, we provide context-sensitive governance strategies tailored to regional priorities. This study highlights the necessity of inclusive, adaptive AI policy frameworks that reflect global disparities while fostering equitable development. The findings offer actionable insights for policymakers, researchers, and practitioners seeking to align AI governance with sustainability and equity goals.

人工智能（AI）已经成为一种变革性技术，有可能加速实现联合国可持续发展目标（sdg）。然而，由于优先事项、社会经济现实和治理能力的不同，发达国家和发展中国家对其采用情况和社会影响差异很大。本研究使用自然语言处理和基于图的多标签分类框架系统地分析了关于人工智能的全球公共话语及其与可持续发展目标的一致性。通过分析社交媒体（Twitter/X）上的249,000多条帖子，并将其归类为与可持续发展目标相关的问题，我们揭示了全球共同的优先事项，例如对可持续发展目标9（工业、创新和基础设施）的强调，以及关键的背景分歧。发达国家注重优化先进系统和道德治理，而发展中国家则强调人工智能在弥合基础设施差距和促进数字公平方面的潜力。值得注意的是，解决人类基本需求的可持续发展目标，如零饥饿（可持续发展目标2）和清洁水和卫生设施（可持续发展目标6），在全球仍未得到充分代表。通过专家驱动的德尔福小组，我们提供针对地区优先事项的环境敏感型治理策略。本研究强调了包容性、适应性人工智能政策框架的必要性，该框架应反映全球差异，同时促进公平发展。研究结果为寻求将人工智能治理与可持续性和公平性目标相结合的政策制定者、研究人员和从业者提供了可操作的见解。

3D-printing of food is an emerging technology that has great potential not only to leading to more efficient food production with less waste but also for developing functional foods, suitable for consumers with specific medical conditions such as dysphagia. An aspect that has not been addressed so far, though, is its environmental performance compared to conventional food production and the potential economic benefits of decentralised 3D-printing of food. We have examined the case of a care home which hosts between 10 and 30 dysphagic residents, with specific dietary requirements, and assessed three alternative scenarios: (a) decentralised 3D printed dysphagic food; (b) centralised 3D printed dysphagic food, distributed to the care home; and (c) centralised conventionally prepared dysphagic food. The analysis has shown that 3D-printing of dysphagic food has a better environmental performance compared to conventionally prepared food, with a 5–13 % improvement in all the midpoint impact indicators. Moreover, the purchase of a 3D-printer by the case home for decentralised production of dysphagic food can be a profitable investment, with the price of conventionally prepared food being the main parameter affecting the decision. A commercial purchase price conventionally prepared food higher than £3.80 per portion of 250 g will definitely render such an investment economically viable, while prices as low as £3.25 can also lead to a viable investment, when the number of residents increases.

食品3d打印是一项新兴技术，它具有巨大的潜力，不仅可以提高食品生产效率，减少浪费，还可以开发功能性食品，适合患有吞咽困难等特定疾病的消费者。然而，到目前为止还没有解决的一个方面是，与传统食品生产相比，它的环境性能以及分散的食品3d打印的潜在经济效益。我们研究了一个护理中心的案例，其中有10到30名患有吞咽困难的居民，他们有特定的饮食要求，并评估了三种替代方案：(a)分散的3D打印吞咽困难食物；(b)集中3D打印的吞咽困难食物，分发给养老院；(c)集中常规制备的消化不良食物。分析表明，与传统制备的食品相比，3d打印的消化不良食品具有更好的环保性能，所有中点影响指标都提高了5 - 13%。此外，购买一台用于分散生产消化不良食品的3d打印机可能是一项有利可图的投资，因为传统制备食品的价格是影响决策的主要参数。如果传统食品的商业购买价格高于每250克3.80英镑，那么这种投资在经济上肯定是可行的，而当居民数量增加时，价格低至3.25英镑也可以导致可行的投资。

Forestry is a vital part of natural systems and has traditionally supplied renewable raw materials for industrial uses and domestic fuelwood. Life Cycle Assessment has become one of the most recognized and internationally accepted method for examining the environmental performance of forest products and processes. The main aim of this study was to evaluate the potential environmental impact associated with different commercial outputs of maritime pine wood (construction wood, pallets, plywood, pellets, unbleached (UB) pulpwood) from the Landes de Gascogne forest. The study showed that pulpwood presented the highest values in all the evaluated impact categories including climate change whilst pellets presented the lowest values. Maritime pine from the first thinning was the hotspot in the construction wood production process, while the nails presented the hotspot for the pallet production process. In the plywood production process, melamine formaldehyde resin was the highest contributor to environmental impacts. Maritime pine from the first thinning was also the hotspot in pellet production whilst heat from steam was the hotspot in UB pulp production. The results of this comprehensive assessment can be used to support environmentally sound decision-making for forest and factory management with regard to the beneficiation of wood.

林业是自然系统的重要组成部分，传统上为工业用途和家庭薪柴提供可再生原料。生命周期评价已成为审查森林产品和过程的环境绩效的最公认和国际接受的方法之一。这项研究的主要目的是评估来自朗德德加斯科涅森林的海洋松木（建筑木材、托盘、胶合板、颗粒、未漂白纸浆木）的不同商业产出对环境的潜在影响。研究表明，在包括气候变化在内的所有评估影响类别中，纸浆木材的价值最高，而颗粒的价值最低。第一次疏伐的海松是建筑木材生产过程中的热点，而钉子是托盘生产过程中的热点。在胶合板生产过程中，三聚氰胺甲醛树脂对环境的影响最大。第一次减薄的海松也是球团生产的热点，而蒸汽产生的热量是UB纸浆生产的热点。这项综合评价的结果可用于支持森林和工厂管理在木材选矿方面的无害环境决策。

This study assesses the environmental impact of producing consumer bath tissue (CBT) in the United States using Brazilian bleached eucalyptus kraft (BEK) and Canadian northern bleached softwood kraft (NBSK) market pulps, in comparison to bamboo-based CBT from China. Additionally, the analysis includes considerations of soil organic carbon (SOC) sequestration from plant growth, and the biogenic global warming potential (GWPbio) based on biomass rotation periods.

Results indicate a cradle-to-grave carbon footprint (CF) of 1824 kg CO₂eq/air-dry ton (ADt) for US CBT (70 % BEK/30 % NBSK) using Light Dry Creped (LDC) technology. Substituting BBK for BEK/NBSK increases CF to 2041 kg CO₂eq/ADt, with Chinese manufactured CBT at 2400 kg CO₂eq/ADt. Using Creped Trough Air Drying (CTAD), CF rises to 2531 and 2739 kg CO₂eq/ADt for BEK-NBSK and BEK-BBK mixtures, respectively. Including SOC factors do not change the conclusions. While the GWPbio factors are highly dependent on the time horizon considered. These results emphasize production technologies' critical role in tissue sustainability and challenge bamboo's perceived environmental advantages.

本研究评估了在美国使用巴西漂白桉树硫酸盐（BEK）和加拿大北方漂白针叶硫酸盐（NBSK）市场纸浆生产消费者沐浴纸（CBT）对环境的影响，并与中国以竹子为基础的CBT进行了比较。此外，该分析还考虑了植物生长对土壤有机碳（SOC）的固存，以及基于生物量轮作周期的生物源全球变暖潜势（GWPbio）。结果表明，使用轻干蠕变（LDC）技术的美国CBT （70% BEK/ 30% NBSK）从摇篮到坟墓的碳足迹（CF）为1824 kg co2当量/风干吨（ADt）。以BBK代替BEK/NBSK可使CF增加到2041 kg CO2eq/ADt，而中国生产的CBT为2400 kg CO2eq/ADt。使用蠕变槽风干（CTAD）， BEK-NBSK和BEK-BBK混合物的CF分别上升到2531和2739 kg CO2eq/ADt。包括SOC因素不会改变结论。而GWPbio因子高度依赖于所考虑的时间范围。这些结果强调了生产技术在组织可持续性中的关键作用，并挑战了竹子的环境优势。

The desalination sector adopts Minimal Liquid Discharge (MLD) systems to become more circular, reduce brine discharge and enhance water recovery, which transforms them to multifunctional systems. This multifunctionality requires a methodologically consistent and goal-aligned approach to environmental impact assessment that recognises how different modelling choices are connected with specific decision contexts. A criterion LCA-based framework aligned with the ISO 14044 hierarchy and tailored specifically to desalination has been developed. It guides the selection of allocation approaches based on system characteristics, integration level, and assessment objectives and is applied to assess an MLD system which co-produces desalinated water, sodium chloride, magnesium hydroxide, calcium hydroxide, sodium sulphate and hydrochloric acid. Multifunctionality was handled with system expansion and partitioning (physical and economic) approaches, resulting in different functional units. For physical and economic partitioning, the MLD system is modelled from a process and system perspective. The results indicate that the MLD system has larger environmental benefits than the reference system with system expansion. When physical and economic partitioning under different perspectives are applied, they result in different environmental burdens per co-product. The MLD system performs better than the reference system (0.005 kg CO₂/kg desalinated water) only when process economic partitioning (0.003 kg CO₂/kg desalinated water) is applied. Whereas, the rest co-products perform better than reference products for all partitioning approaches applied. Our results highlight the potential of brine as a secondary source of products. This study underscores the importance of selecting appropriate allocation approaches, contributing to sustainable practices in the desalination sector.

海水淡化行业采用最小液体排放（MLD）系统，以实现更循环、减少盐水排放和提高水回收率，从而将其转变为多功能系统。这种多功能性需要一种方法上一致和目标一致的方法来进行环境影响评估，认识到不同的建模选择如何与特定的决策背景相关联。基于lca的标准框架与ISO 14044层次结构保持一致，并专门针对海水淡化开发。根据系统特点、集成水平和评价目标，指导配置方式的选择，并应用于对淡化水、氯化钠、氢氧化镁、氢氧化钙、硫酸钠和盐酸共产MLD系统进行评价。通过系统扩展和划分（物理的和经济的）方法来处理多功能性，从而产生不同的功能单元。对于物理和经济分区，从过程和系统的角度对MLD系统进行建模。结果表明，随着系统的扩展，MLD系统比参考系统具有更大的环境效益。当应用不同视角下的物理和经济分区时，它们会导致每个副产品的环境负担不同。仅当采用工艺经济分配（0.003 kg CO2/kg淡化水）时，MLD系统的性能才优于参考系统（0.005 kg CO2/kg淡化水）。然而，对于所有应用的划分方法，其余的副乘积都比参考乘积表现得更好。我们的研究结果强调了卤水作为产品二次来源的潜力。这项研究强调了选择适当的分配方法的重要性，有助于海水淡化部门的可持续实践。

Product-as-a-Service (PaaS) is a circular business model that allows original equipment manufacturers (OEMs) to enhance their product offerings, and capture the economic value by cascading value retention processes like repair, reuse, refurbishment, remanufacturing, and afterward recycling. The shift from traditional product ownership models to PaaS models requires a systemic transformation in how products are designed, delivered, and supported. In this paper we focus on the PaaS models for electrical and electronic equipment (EEE) for consumer markets. To ensure successful deployment we identify four key pillars of PaaS transformation: product design, service offerings, enabling technologies and supporting infrastructure. Through this research, we explore how identified challenges can be linked to indicators and guidelines as potential solutions for each of the four pillars. By applying PRISMA and bibliometric analysis, we identified 229 challenges, 182 indicators, and 169 design barriers and categorize them within the four fundamental pillars of PaaS: products, services, technologies, and infrastructure. Our findings highlight a notable deficiency in performance indicators and design guidelines related to both infrastructure and technology, resulting in a lack of methods and tools to support the development of circular PaaS offerings and ecosystems. This study suggests relating challenges, performance indicators, and design guidelines with each other for ultimately coming up with PaaS decision guidance for both designers and decision makers.

产品即服务（PaaS）是一种循环商业模式，它允许原始设备制造商（oem）增强其产品供应，并通过诸如维修、再利用、翻新、再制造和随后的回收等层叠价值保留过程获取经济价值。从传统的产品所有权模型到PaaS模型的转变需要在如何设计、交付和支持产品方面进行系统的转换。在本文中，我们关注的是面向消费者市场的电子电气设备（EEE）的PaaS模型。为了确保成功部署，我们确定了PaaS转型的四个关键支柱：产品设计、服务提供、启用技术和支持基础设施。通过这项研究，我们探索了如何将已确定的挑战与指标和指导方针联系起来，作为四大支柱的潜在解决方案。通过应用PRISMA和文献计量分析，我们确定了229个挑战、182个指标和169个设计障碍，并将它们归类为PaaS的四个基本支柱：产品、服务、技术和基础设施。我们的研究结果突出了与基础设施和技术相关的性能指标和设计指南的显着缺陷，导致缺乏支持循环PaaS产品和生态系统开发的方法和工具。本研究建议将挑战、性能指标和设计指南相互联系起来，最终为设计师和决策者提供PaaS决策指导。

The automotive industry plays a crucial role in climate change mitigation due to its significant share of global greenhouse gas (GHG) emissions across the life cycle of its products. As a result, many original equipment manufacturers (OEMs) have adopted absolute or relative carbon reduction targets covering scope 1–3 emissions. However, there is a lack of industry-wide insight into how these efforts align with the reductions needed to meet a well-below 2 °C or 1.5 °C climate pathway. This paper addresses this gap through a scenario analysis of major automotive manufacturers from 2020 to 2050. Starting from OEM GHG inventories for 2020, sector decarbonization pathways (SDPs) are developed for all scope 1–3 emission categories, focusing on key emission hotspots. Three comparative scenarios (benchmark, ambitious, net-zero) are constructed and compared to an OEM-based scenario reflecting current corporate targets and production plans. The analysis reveals that published OEM targets are insufficient in both scope and ambition to meet the well-below 2 °C target. Moreover, substantial differences exist among OEMs regarding target coverage, ambition levels, and timelines. To enable a more effective decarbonization of the automotive sector, urgent, comprehensive, and collaborative action is needed. This includes robust portfolio planning, the adoption of clear and ambitious climate targets, and the development of actionable strategies—particularly in addressing future emission hotspots, notably scope 3 category 1.

汽车行业在其产品的整个生命周期中占全球温室气体（GHG）排放的很大份额，因此在减缓气候变化方面发挥着至关重要的作用。因此，许多原始设备制造商（oem）采用了涵盖范围1-3排放的绝对或相对碳减排目标。然而，对于这些努力如何与远低于2°C或1.5°C的气候路径所需的减排相一致，整个行业缺乏洞察力。本文通过对2020年至2050年主要汽车制造商的情景分析来解决这一差距。从2020年OEM温室气体清单开始，针对所有范围1-3的排放类别制定行业脱碳路径（sdp），重点关注关键排放热点。构建了三种比较情景（基准、雄心和净零），并与基于oem的情景进行了比较，反映了当前的企业目标和生产计划。分析显示，公布的OEM目标在范围和力度上都不足以实现远低于2°C的目标。此外，在目标覆盖范围、目标水平和时间表方面，oem之间存在巨大差异。为了使汽车行业实现更有效的脱碳，需要采取紧急、全面和协作的行动。这包括强有力的投资组合规划，采用明确和雄心勃勃的气候目标，以及制定可操作的战略，特别是在解决未来的排放热点方面，特别是第3类第1类。

Sustainability labelling gained prominence in food policy discourse in recent years, particularly in Europe, although its effectiveness in influencing consumer behaviour remains uncertain. This work explores selected sustainability food labels in the EU, reviewing sustainability indicators and the underlying life cycle assessment (LCA) methodologies. It addresses methodological approaches, and how they apply LCA with reference to the Product Environmental Footprint (PEF) method recommended by the European Commission. Four labels were identified from a comprehensive product database, focusing on labels applying LCA and quantifying multiple impacts, while an additional one was identified from the current EU panorama. An evaluation framework was developed on the relevant methodological aspects, encompassing governance, transparency, and clarity. Interviews with label developers complemented the analysis, along with a review of criticisms of LCA and PEF for labelling purposes. Four are scoring labels providing graded and colour-coded visuals, while one is still under development. Methodological adaptations to the PEF were common, and non-LCA sustainability assessments accounted for aspects such as farming management, social issues, and biodiversity. Labels varied in transparency, stakeholder involvement, and clarity. Criticisms of LCA include its reductionist approach, data gaps, and lack of robust methodologies for assessing biodiversity. While sustainability labelling is important to guide sustainable choices, labels need to be part of a broader policy mix and should be underpinned by clear goals and robust methodologies. This analysis will help to develop evidence-based policy instruments for sustainable consumption and set the basis for a harmonized labelling system.

近年来，可持续性标签在食品政策话语中获得了突出地位，特别是在欧洲，尽管其在影响消费者行为方面的有效性仍不确定。这项工作探讨了欧盟选定的可持续性食品标签，审查可持续性指标和潜在的生命周期评估（LCA）方法。它讨论了方法方法，以及它们如何根据欧洲委员会推荐的产品环境足迹（PEF）方法应用LCA。从综合产品数据库中确定了四个标签，重点关注应用LCA和量化多重影响的标签，同时从当前的欧盟全景中确定了另外一个标签。在相关的方法方面开发了一个评估框架，包括治理、透明度和清晰度。与标签开发商的访谈补充了分析，以及对LCA和PEF用于标签目的的批评的回顾。四个是评分标签，提供分级和颜色编码的视觉效果，而一个仍在开发中。对PEF的方法调整是常见的，非lca可持续性评估考虑了农业管理、社会问题和生物多样性等方面。标签在透明度、涉众参与度和清晰度方面各不相同。对LCA的批评包括其简化方法、数据缺口以及缺乏评估生物多样性的可靠方法。虽然可持续性标签对指导可持续选择很重要，但标签需要成为更广泛的政策组合的一部分，并应以明确的目标和有力的方法为基础。这项分析将有助于制定以证据为基础的可持续消费政策工具，并为统一的标签制度奠定基础。

To meet stringent climate goals, regions in the EU need tools to facilitate the sustainable energy transition. Localized energy systems offer a promising solution. Although concepts such as energy communities have been promoted, there remains a gap in the literature and practice regarding systematic approaches to locate and evaluate sites for local energy ecosystems. We introduce a process that evaluates these ecosystem sites using four technical factors: energy consumption volume, wind and solar energy potential, and energy infrastructure availability. The process utilizes the multi-criteria decision analysis methods Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) and analytic hierarchy process. We applied this approach in the region of Päijät-Häme, Finland, identifying seven potential sites, with Kujala and Nastola standing out as the alternatives having highest potential. Higher energy consumption density or solar energy availability did not always correlate with better synergy potential. Instead, the results showed that energy ecosystem potential is formed from a combination of factors, of which energy infrastructure is the most important one in the regional case. These outcomes align with prior research and indicate that the proposed factors can effectively capture energy ecosystem potential. The study provides an applicable approach for regional energy planning.

为了实现严格的气候目标，欧盟各地区需要工具来促进可持续能源转型。本地化能源系统提供了一个很有前途的解决方案。虽然诸如能源社区之类的概念得到了推广，但在文献和实践中，关于定位和评估当地能源生态系统地点的系统方法仍然存在差距。我们引入了一个过程，使用四个技术因素来评估这些生态系统站点：能源消耗量、风能和太阳能潜力以及能源基础设施的可用性。该过程采用了多准则决策分析方法——理想解相似偏好排序法（TOPSIS）和层次分析法。我们在芬兰Päijät-Häme地区应用了这种方法，确定了七个潜在的地点，其中Kujala和Nastola脱颖而出，成为最有潜力的备选地点。较高的能源消耗密度或太阳能可用性并不总是与较好的协同潜力相关。结果表明，能源生态系统潜力是多种因素共同作用的结果，其中能源基础设施是区域案例中最重要的因素。这些结果与先前的研究结果一致，表明所提出的因素可以有效地捕捉能源生态系统的潜力。该研究为区域能源规划提供了一种适用的方法。

As the global pursuit of the “dual carbon” goals continues to accelerate, the realization of carbon emission reduction and green transformation through institutional innovation has emerged as a critical scholarly and policy concern. Based on city-level data from 283 Chinese cities between 2012 and 2023, this study systematically examines the impact of institutional openness on carbon emission reduction and urban green transition, and conducts empirical tests on the underlying mechanisms. The findings reveal that institutional openness can be regarded as a significant catalyst for carbon reduction. Disaggregated analyses indicate that the transformation of government functions exhibiting the most pronounced effect. Mechanistic investigations suggest that institutional openness can foster green low-carbon transformation through multiple pathways, including the promotion of emerging industries, the elevation of intelligent manufacturing, the stimulation of green patent innovation, and the enhancement of green total factor productivity. Moreover, the carbon mitigation effects are found to be more salient in eastern China, resource-based cities, and cities hosting data trading platforms. Further evidence suggests that institutional openness not only significantly curtails carbon emissions, but also exerts a positive influence on the source control of major industrial pollutants such as wastewater and particulate matter. This study provides both a theoretical underpinning and policy reference for the coordinated advancement of institutional openness and green transformation in China and internationally.

随着全球对“双碳”目标的追求不断加快，通过制度创新实现碳减排和绿色转型已成为一个重要的学术和政策问题。基于2012 - 2023年中国283个城市的数据，系统考察了制度开放对碳减排和城市绿色转型的影响，并对影响机制进行了实证检验。研究结果表明，制度开放可被视为碳减排的重要催化剂。分类分析表明，政府职能转变的效果最为显著。机制研究表明，制度开放可以通过促进新兴产业、提升智能制造、激发绿色专利创新和提高绿色全要素生产率等多种途径促进绿色低碳转型。此外，中国东部地区、资源型城市和数据交易平台城市的碳减排效果更为显著。进一步的证据表明，制度开放不仅显著减少了碳排放，而且对废水和颗粒物等主要工业污染物的源头控制产生了积极影响。本研究为国内外制度开放与绿色转型的协调推进提供了理论支撑和政策参考。
