However, the resource use and carbon emissions associated with the anticipated expansion of roads, railways, and other mobility infrastructure, as well as the potential of mitigation measures, have so far not been explored systematically. Using high-resolution infrastructure and mobility data, we assess seven demand- and four supply-side circular economy and decarbonization measures aiming to mitigate resource use and associated embodied CO₂ emissions. We find that without demand reduction, infrastructure stocks could double or triple by 2060, with cumulative emissions reaching 10 to 20 GtCO₂. We find that a global shift to rail would increase embodied emissions to 37 GtCO₂ due to carbon-intensive materials. Combining mobility reduction with enhanced recycling and industrial decarbonization can cut emissions by 63% while providing adequate global infrastructure. This would help to offset increases in emissions from public transport infrastructure expansion required to reduce operational emissions.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44498-026-00132-x.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"30 4","pages":"1935-1949"},"PeriodicalIF":5.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13451253/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148697646","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 developed model can explore different retrofit deployment rates to limit emissions of the existing building stock, and be used to develop different pathways which could meet carbon budgets for varying future scenarios. We illustrate the application of the model to the English school stock, comprising approximately 20,000 schools. In applying the model, we find that an estimated school carbon budget is only met with a significant increase in retrofit rates from current ambitions, alongside significant decarbonization in electricity and material sectors. When retrofit modeling is applied at scale, the aggregated impacts of material consumption are highlighted, and the most stringent carbon budget cannot be met when a whole life carbon approach is taken. Heat pumps and active ventilation systems pose a significant carbon hot-spot due to the use of carbon-intensive materials and regular replacement rates. These systems would therefore benefit from research and development to reduce their impacts. The developed model also allows for a stock level comparison of retrofit to the alternative of demolition and new construction (to different future standards). We show that retrofit provides the lowest whole life carbon solution over the 25 year study period for all buildings, compared to proposed ambitious UK whole life carbon targets.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44498-026-00027-x.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"30 1","pages":"391-403"},"PeriodicalIF":5.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13152907/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147868501","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}

{"title":"The climate cost of lateness: decomposing historical drivers of CO₂ industrial emissions during Spanish industrialization and deindustrialization, 1890-2021.","authors":"Ángel Sanjuán-Ruiz, Juan Infante-Amate, Eduardo Aguilera","doi":"10.1007/s44498-026-00077-1","DOIUrl":"10.1007/s44498-026-00077-1","url":null,"abstract":"<p><p>Industry accounts for ~ 34% of global CO₂ emissions, positioning it as the largest single contributor to anthropogenic climate change. Understanding the historical trajectory is essential for effective mitigation, yet most analyses are short-term and long-term studies rarely examine industry. This article reconstructs consistent long-run series of industrial CO₂ emissions in Spain from 1890 to 2021, disaggregated by source (direct, indirect, and process-related) and by sector. Combining newly harmonized historical energy accounts with decomposition techniques (IPAT and additive LMDI), we quantify the relative contribution of value added, energy intensity of production, carbon intensity of energy use, and structural change to industrial CO₂ emissions trajectories. Emissions increased twenty-sevenfold between 1890 and 2007, with the sharpest rise occurring during 1950-1973. Spain's path reflects a double delay: late industrialization produced a compressed, fossil-fuel-intensive take-off, while delayed adoption of efficient and low-carbon technologies after the 1970s reinforced carbon lock-in. Improvements in energy and carbon intensity have been consistently outpaced by output growth, revealing rebound effects and the limits of relative decoupling. As a late joiner, Spain shows how delayed industrial development shaped CO₂ emissions trajectories, as the dominance of non-metallic and building-materials industries produced a volatile, non-linear decline in carbon intensity, keeping it above early-industrializer levels into the twenty-first century. Deep decarbonization therefore requires targeted interventions in a small set of structural \"hotspots,\" alongside technological upgrading and material circularity to overcome the historical legacy of late development.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44498-026-00077-1.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"30 3","pages":"1129-1145"},"PeriodicalIF":5.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13342420/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148411860","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, spatial material stock studies often produce coarse results owing to challenges in material intensity development. This paper introduces BUD-MI (Bottom-Up Data: Material Intensity), a material intensity data collection template designed with three core objectives: streamlining the data collection process during building sampling, supporting cumulative research while ensuring project-specific relevance, and enhancing the utility of results for the construction industry. BUD-MI aims to assist researchers, students, and construction practitioners in developing material intensity data in line with these three objectives. The development process required identifying material intensity challenges, eliciting requirements, mapping relevant domain work and creating missing ones, and assembling them all into BUD-MI. The template consists of three data input tabs, two mini-tools for data input assistance, four result generation tabs, and additional tabs for background data and ancillary information. A case study in Sheffield, UK, illustrates BUD-MI's functionalities, enabling bespoke material intensity results to be disaggregated across building elements and components. BUD-MI supports future material intensity data collection efforts, ensuring data quality, granularity, comparability, transferability, and availability, thereby advancing socioeconomic metabolism and circular economy research and practice.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s44498-026-00044-w.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"30 2","pages":"631-649"},"PeriodicalIF":5.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13226353/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148156777","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}

Using a research-through-design approach, four alternative concepts were developed: a fully recyclable device, a partially reusable device, a multifunctional device, and a manual device, aiming to reduce the carbon footprint while maintaining clinical performance of the device. Iterative design cycles incorporated feedback from Medtech professionals and from qualitative surveys with additional industry stakeholders. Fast-track life cycle assessments (LCAs) estimated environmental impact compared to the baseline device, while stakeholder feedback assessed trade-offs and synergies related to safety, usability, workflow compatibility, and regulatory compliance. Here, \"trade-offs\" refer to improvements in circularity coming with losses in other requirements, while \"synergies\" improve both circularity and other requirements together. Results revealed that each concept delivered potential carbon footprint reductions, particularly the reusable, multifunctional, and manual variants. Trade-offs included increased sterilization burden, altered surgical workflow, and reduced user familiarity; synergies included lower material and logistics costs from reuse and multifunctional design, achieved without compromising safety or usability. The findings highlight that achieving circularity in medical device design involves more than technical considerations; it requires a systems-level approach. Effective implementation depends on aligning design strategies with regulatory requirements, clinical workflows, and supply chain practices. This study provides recommendations to navigate trade-offs and identify synergies, supporting a structured approach to advancing sustainable practices in healthcare.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at https://doi.org/10.1007/s44498-026-00189-8.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"30 5","pages":"2697-2713"},"PeriodicalIF":5.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13649933/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149167535","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 estimates future iridium demand for PEMEL under various global deployment scenarios and technological advances. Results show that meeting net zero targets will require both significant improvements in catalyst efficiency and access to roughly 30% of global iridium production annually. Supply shortages could arise as early as 2030, earlier than previously anticipated. The analysis also reveals that long-term iridium needs beyond 2040 are significantly underestimated.

Results show that residential building footprints, i.e., the ground area covered by buildings, useful floor area, and material stocks scale moderately sub-linearly (scaling exponent <i>β</i> in the [0.82, 0.89] interval). Non-residential buildings and mobility infrastructure (area, materials) scale more strongly sub-linearly (<i>β</i> in the [0.42, 0.74] interval). These patterns are robust across sensitivity tests.

A key low-cost strategy to achieve this is to substitute Portland clinker in cement with lower carbon materials. However, high-quality inventory data for clinker substitutes are poorly available, which limits the application of life cycle assessment (LCA) to quantify the carbon footprints of cements containing them. Here, we report the state-of-the-art inventory data for clinker substitutes, disaggregating them by unit process to facilitate comparison, improve proxy data selection, and identify gaps to inform future data collection efforts. Cradle-to-gate greenhouse gas emissions for European production of the clinker substitutes and carbon footprints of composite cements defined in EN 197 are calculated. Overall, we find the degree of clinker substitution, rather than the processing of clinker substitutes, is more impactful for producing low carbon footprint cements.

This research addresses this gap by developing and applying an interpretation-based semantic network analysis linking CEBM patterns to rebound mechanisms via triggers and drivers. The three primary contributions are: (1) a first semantic network of the associations between CEBM patterns and rebound mechanisms, offering important structural insights; (2) a clear positioning of triggers and drivers as the essential, actionable links between CEBM and RE; and (3) an operational causal ontology and complementary analytical procedures to support RE analysis within sustainability transitions.
