Performance ratings (e.g., A–E) are derived from life cycle assessment (LCA) results to enable comparison between products. The translation of LCA results to performance ratings requires definition of a common rating scale, either at a sector level or for subsets of products grouped by function (i.e., product categories). We investigate if and how assigning products to distinct categories influences final product ratings in ERE schemes. We consider if product categorization enables increased product differentiation and how the structure of categories affects the ratings awarded to products. Using a food sector case study, ratings were assigned to 2253 products based on aggregated environmental single scores derived from Agribalyse 3.1 and ratings obtained under three scenarios were compared: (1) no categorization—all products are placed on a single scale before rating; (2a) food group categorization—products are assigned to 11 food groups described in the Ciqual food composition database; and (2b) food subgroup categorization—products are assigned to 61 Ciqual food subgroups. We find that categorization has a significant influence on the final ratings, affecting at least 54% of products evaluated. Categorization restricts the range of products that can be compared but does not systematically improve differentiation within categories. For categorization to be used in ERE, categorization hierarchies need to be developed and harmonized at sector level reflecting consumer-relevant substitution options. This study demonstrates that categorization is a key methodological consideration for ERE scheme developers.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 4","pages":"1335-1349"},"PeriodicalIF":5.4,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782862","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}

Despite limited fiscal capacity, there is a plan in Romania to produce low-carbon steel. We draw on a unique dataset collected by the Energy Policy Group estimating a production cost between €537 and €794 per ton of low-carbon steel. Based on this, we analyze the decarbonization of Romania's sole primary steel producer—one of the top 10 most polluting steel plants in the European Union—using a marginal shift analysis and an investment appraisal. The emissions of this steelmaker currently stand at 1.87 tons of carbon dioxide per ton of steel, and its ambition is to become carbon neutral by 2030. Our scenario analysis examines the outcomes of decarbonization under different hydrogen sourcing strategies and reveals that a 15% price premium is needed for green steel to be competitive when hydrogen is purchased externally as opposed to being produced on-site through electrolysis. Without this premium, the net present value analysis from 2030 to 2050 estimates a cumulative loss between €3.3 and €8.7 billion. These results are highly sensitive to hydrogen sourcing and electricity prices, underscoring the importance of infrastructure, price certainty, and policy support in achieving decarbonization.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 4","pages":"1322-1334"},"PeriodicalIF":5.4,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70054","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782737","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}

The approach was piloted to explore how shifts toward sustainable circulation of materials in Swedish transportation infrastructure could be enabled. Semi-structured interviews were used to collect actors’ assumptions on system failures as well as drivers and possible interventions, supported by the system failures framework of Weber and Rohracher. Seven priority areas for interventions were suggested. A causal loop diagram as well as a simplified version here referred to as “transition logics” were then prepared and used to explore paths toward enabling the desired shift, including possible near-term priorities considering interactions between suggested priority areas for interventions.

Addressing this challenge requires scalable methods for estimating the dimensions of interior components across large building stocks. In this study, we introduce the UKResi dataset, a novel dataset containing 2000 residential houses in the United Kingdom, designed to predict interior wall systems and room-level spatial configurations using exterior building features.

Furthermore, we analyze the driving factors influencing wall length and room predictions using permutation importance and SHapley Additive exPlanations values, providing insights into feature contributions, especially facade opening information being a critical driving factor of modeling interior features. The UKResi dataset serves as a foundation for future component-level building stock modeling, offering a scalable and data-driven solution to assess building interiors.

Although it is customary for residential buildings to lose value in the real estate market when they exceed their statutory lifetimes, this rapid reconstruction cycle poses an environmental burden. However, increasing the proportion of new housing units built according to strict energy-saving standards could have a positive environmental impact. Research on the economic lifetime of buildings remains insufficient, and the trade-offs between the impact of demand in the national housing stock on CO₂ emissions and the impact of reconstruction on CO₂ emissions throughout an economic lifetime remain under-researched. Therefore, this study investigates the impact of the economic lifetime of Japanese detached wooden residential buildings on CO₂ emissions during the construction and use phases. Specifically, it estimates the economic lifetime of detached wooden residential buildings based on real estate transaction data and assesses the effects of changes in CO₂ emissions during the construction and use phases by altering the average lifetime. The results display that a shorter economic lifetime of residential buildings significantly contributes to increased CO₂ emissions, whereas gradual lifespan increases contribute to a decrease, thereby making a strong case for reassessing the statutory useful life of residential buildings. This study provides evidence that maintaining the economic lifetime of buildings and transitioning to ambitious extensions are crucial aspects of environmental policies</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 4","pages":"1265-1278"},"PeriodicalIF":5.4,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782676","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 study employs complex network analysis and the cascading failure model to assess the supply chain security of the global palladium trade network during 1990–2023. The results show that the network structure is shaped by multiple factors including geopolitics, economic climates, and industrial technology. A notable decrease in the concentration of palladium supply has been observed, with higher network densities, average clustering coefficients, and shorter path lengths indicating the network's enhanced aggregation, transmission efficiency and overall resistance ability to risks. However, the recent intensification of global geopolitical situations has led to a trend of reconfiguration and isolation, progressively partitioning the network into communities of North America, Western Europe, and Russia-East Asia, while elevating the geographical proximity as a crucial factor in trade. Despite the fact that Russia and South Africa, as major producers and suppliers of palladium, play significant roles in the spreading of supply chain crises, the central status of the network remains dominated by palladium consumers and transit countries. The risk matrix assessment demonstrates that supply risks have declined more substantially than vulnerabilities, revealing that the improvements in palladium's supply chain security are more dependent on mitigating the severity of a potential supply disruption rather than its likelihood.

Construction and demolition waste (C&amp;DW) is therefore considered a potentially significant source of secondary materials for the future. To prolong the service time of these end-of-use products within the construction sector, innovative business models for effectively utilizing these urban mines are emerging, with direct reuse strategies being one practical solution. Among various types of C&amp;DW, the inherent properties of steel make it particularly favorable for direct reuse. This study develops a hybrid input–output analysis and environmental extended input–output analysis model to assess the economic and environmental impact of applying a direct reuse strategy in the construction sector, with a focus on end-of-use structural steel products from end-of-service buildings. Under the scenario that end-of-use structural steel is directly reused, the economy may experience slight output value losses owing to reduced demand for raw material and remanufacturing sectors. However, it can result in significant carbon reduction impacts on energy and raw material sectors. Moreover, the carbon reduction achieved through the direct reuse strategy is around 25% of that achieved by transitioning from blast furnace-basic oxygen furnace (BF-BOF) steelmaking process to direct reduced iron-electric arc furnace (DRI-EAF) steelmaking process.
