This study develops an environmentally extended input–output (EE-IO) model based on an original social accounting matrix combined with a structural path analysis (SPA) to assess the annual domestic plastic footprint in Côte d'Ivoire, estimated at 19 kg per capita but standing on a steadily growing trend. This first quantification identifies several key sectors (machinery and equipment, transport, furniture, paper and printing, food industry) contributing significantly to the domestic plastic consumption and waste.

Leadership in Energy and Environmental Design (LEED) is a widely used green building certification that aims to align projects with future climate and energy goals. However, many LEED credits do not fully reflect the principles of long-term sustainability. LEED credits were compared to ecological food web structures using ecological network analysis (ENA) to better assess building sustainability, a method that emphasizes system-level balance and resource cycling. When applied to LEED scorecards for 1266 newly constructed buildings, ENA revealed that restructuring credits based on system impact, particularly cyclicity, provides a clearer picture of building performance. The proposed grENA model showed an increase in system cyclicity from 1.00 in LEED to 4.18, capturing critical community-level effects. Ecological networks often exhibit higher cyclicity due to organized recycling, a feature largely underrepresented in current LEED priorities. Results also showed that 37% of buildings had inflated LEED certifications, indicating misalignment between awarded points and true sustainability. The proposed model supports more resilient building design by emphasizing balanced subsystems and community integration. These findings highlight the value of sustainable urbanism, where features like green spaces, efficient public transport, and mixed-use developments enhance livability while minimizing environmental impact. A holistic, systems-based approach ensures that buildings not only meet energy goals but also contribute positively to their broader urban ecosystems.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1776-1790"},"PeriodicalIF":5.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work introduces a multi-method approach by combining process simulation, techno-economic analysis, life cycle assessment, renewable electricity generation modeling, and multi-objective optimization to investigate the relationship between PtX production costs and greenhouse gas emissions to support investment decisions. The approach is applied to produce renewable hydrogen, Fischer–Tropsch crude, and methanol by considering global weather data with hourly temporal resolution. Our results show that locations with high wind capacity factors achieve the lowest costs and greenhouse gas emissions, and locations with high solar PV capacity factors perform worst in the context of greenhouse gas emissions when producing PtX products, primarily due to the emission-intensive production of solar PV modules. Locations with mixed capacity factors of wind and solar PV allow cost-efficient greenhouse gas emissions reduction since solar PV capacities can be substituted with a combination of wind generation capacities and battery storage. In addition, flexible PtX technologies reduce costs and greenhouse gas emissions significantly since fewer auxiliary components, like storage, are needed.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1791-1805"},"PeriodicalIF":5.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70085","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this shift could significantly increase the demand for nonferrous metals that are intensive in Hg, potentially negating the benefits of reduced Hg emissions. The effect of these nonferrous metal inputs on the overall effectiveness of Hg reduction efforts within the power sector's transition is an area that requires further investigation. Here, we evaluate the impact of China's low-carbon power transition on Hg emissions from coal combustion and nonferrous metal (mainly copper, zinc, and lead) smelting. We find that the low-carbon power transition will lead to a significant reduction (101.81 tons) of over 90% in annual Hg emissions originating from coal combustion during the period from 2021 to 2060. Unexpectedly, the pursuit of renewable energy, particularly in photovoltaic and wind power, is likely to result in a twofold increase in annual mercury (Hg) emissions from nonferrous metal smelting, totaling 5.07 tons, under current industry practices. The cumulative emissions from nonferrous metal smelting is estimated to be 370.44 tons during 2021–2060, including 65.80% power transmission equipment related and 34.30 % power generation equipment related emissions. Overall reduction through the adoption of coordinated measures in the power and nonferrous metals sectors could cut cumulative Hg emissions from nonferrous metal smelting by 57% (211.37 tons) during 2021–2060. The study emphasizes the critical need to manage emissions from metal production for a sustainable low-carbon energy transition.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1763-1775"},"PeriodicalIF":5.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The established method of life cycle assessment (LCA), designed to evaluate static processes, reaches its limits when applied to changing systems. We have conducted a systematic literature review on time-differentiating LCA methods for assessing transforming processes in their transition toward climate neutrality. On closer examination, three major types of dynamics emerge: transition dynamics, process dynamics, and dynamic impact assessment. Transition dynamics represent the gradual modification of the production. Process dynamics take into account the duration of processes and their temporal dependency on each other. Dynamic impact assessment demonstrates how the biosphere reacts to dynamic emissions. The reviewed literature delivered several examples of prospective LCA dealing with scenario integration or ex ante observations of emerging technologies. These typically differentiate only the transition temporally. By contrast, some methodology papers for dynamic LCA cover all three types of dynamics. Those comprise absolute changes and relative time dependence between processes, as well as metrics for the dynamic impact assessment of greenhouse gases. In conclusion, literature uses the terms dynamic and prospective LCA for overlapping research areas, both of which are highly relevant for evaluating a transforming system. However, methods are mostly applied separately in use cases also not related to an explicit decarbonization target. Aiming for harmonization of both concepts, we identified promising building blocks in a combined dynamic and prospective LCA to assess transition paths toward climate-neutral production.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1523-1550"},"PeriodicalIF":5.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Archetype-based bottom-up material stock analysis (MSA) is increasingly used to estimate the quantity, location, and embodied carbon of different construction materials within existing buildings. European MSA studies typically employ archetypes based on building use (e.g., residential/non-residential) and/or age (e.g., historic/modern), potentially missing significant variation in material composition across different construction types. Such work also generally focuses on residential buildings and derives aggregated and/or synthetic material intensities (MIs), with non-residential buildings in the United Kingdom rarely being considered through real-world design data. This paper investigates the suitability of different archetyping approaches in the bottom-up estimation of material stocks and embodied carbon in UK buildings. Concrete is revealed to consistently contribute the majority of material mass irrespective of use or construction type, with steel consistently representing a majority of superstructural embodied carbon. Despite the relative agreement between overall structural MIs for use- and construction-based archetypes, varying material and sub-/superstructural composition introduces increased heterogeneity in individual-material and sub-building MIs when considering building construction type. Mapping of use- and construction-based MIs to the building stock level is shown to be inhibited by the infrequent specification of construction type within the utilized inventory. This gives rise to a novel, parallel use and/or construction archetyping approach, reiterating the need for the inclusion of building construction types within both MSA archetyping approaches and national building inventories.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1748-1762"},"PeriodicalIF":5.4,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70066","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in the European Union (EU), the development of the CE has been hindered by technological, economic, regulatory, and cultural barriers, leaving its compelling moral case significantly under-implemented. Drawing on Luhmann's systems theory, this forum article reconceptualizes the moral case for the CE as a normative expectation—a societal “ought” that retains its validity even when violated. These violations, we argue, function as productive irritations, catalyzing the evolution of the CE by driving innovation, societal critique, and gradual adaptation. We analyze this evolutionary trajectory by distinguishing three stages of CE development in the EU: (i) semantic articulation, (ii) structural consolidation, and (iii) emergent alignment of semantics and structures.
