The transport sectors of the United States, China, and Russia are the main national sectors. GTCEN's small-world topology reveals amplified supply-side mitigation efficiency, pinpointing high-leverage sectors, such as Canada's road transport, United States' air/rail transport, China's water transport, and Russia's pipeline transport. We recommend prioritizing technological upgrades in these high-impact sectors, fostering cross-sectoral governance, and aligning policies with supply-side decarbonization.

Fourteen environmental, socio-economic, and infrastructural criteria were incorporated to generate thematic layers, and their relative importance was assessed using AHP. Eight candidate sites were subsequently evaluated using the CODAS method, enabling identification of the most suitable location for landfill development. The results indicate that land-use characteristics, economic considerations, and terrain conditions exert a dominant influence on site suitability. Sensitivity analysis conducted across multiple weighting scenarios confirmed the robustness of the results, with less than 5% variation in suitability scores and the overall site hierarchy remaining stable. The proposed framework demonstrates the effectiveness of combining AHP, CODAS, and GIS-based spatial analysis to support systematic, transparent, and evidence-based landfill site selection, providing a practical decision-support tool for sustainable waste management planning in rapidly urbanizing regions.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"548 ","pages":"Article 147832"},"PeriodicalIF":10.0,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147278724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

However, the phytohormonal composition of frass produced by <em>Hermetia illucens</em> (black soldier fly, BSF) larvae remains insufficiently characterized. This study provides a comprehensive assessment of 3 major phytohormone group in BSF frass and frass leachates derived from the bioconversion of pea (PW) and bean (BW) seed waste - representative agri-food by-products from legumes. Both substrates supported efficient larval development, with BW frass exhibiting higher concentrations of indole-3-acetic acid, stress-related hormones, and total sum of cytokinins, while PW leachates contained elevated levels of trans-zeatin, cis-zeatin and IP. IAA and some cytokinines were also detected in the larvae, suggesting metabolic interactions between insects, microbiota, and substrates. Overall, our findings reveal that BSF-mediated waste bioconversion enhances the phytohormonal composition of frass more than its decomposition with only microbiota, thereby increasing its potential as a multifunctional, eco-friendly biofertilizer. This approach illustrates how insect bioconversion can add functional value to agri-food waste within sustainable production systems.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"548 ","pages":"Article 147855"},"PeriodicalIF":10.0,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147411330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

This study investigates the impact of the household singlehood rate on per capita carbon emissions from a consumption-based perspective.

The impact is channeled through three mechanisms: diminished economies of scale in household public goods, insufficient sharing of domestic energy, and increased per capita consumption driven by convenience-seeking behaviors. Heterogeneity analyses uncover systematic disparities: the effect is strongest for males, rural dwellers, the youth, high-income earners and high-education singlehood households. Based on these insights, we propose targeted policy recommendations focused on leveraging learning curves, intervening at sensitive points, and implementing personal carbon budgets to systematically guide and incentivize low-carbon transitions among the singlehood population.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"548 ","pages":"Article 147631"},"PeriodicalIF":10.0,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147278678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

However, the diversity of existing methods, each with distinct data requirements and assumptions, creates challenges in selecting appropriate approaches, especially during early project stages when data are sparse. This study presents a structured, six-tier framework that guides users in selecting and applying suitable estimation techniques based on the maturity of geological and operational data. The framework integrates static, analytical, and numerical methods into a progressive, adaptive structure. It enables meaningful, constraint-aware estimates at any stage of development, even when only limited inputs are available, and supports refinement as more detailed data emerge. Each tier builds upon the last by introducing increasingly advanced methods, beginning with basic volumetric estimates and advancing through pressure-constrained calculations, injectivity modeling, and full-physics dynamic simulations. At every level, the framework provides recommended parameter ranges, fallback values, and structured uncertainty bracketing to ensure transparency and methodological rigor. Initial estimates are retained and iteratively refined, yielding progressively narrower and more defensible capacity ranges. The novelty of the framework lies in its ability to generate credible CO₂ storage estimates under any data condition and to guide practitioners through a clear, step-by-step method selection process. It offers a unified, scalable, and uncertainty-aware workflow that supports screening and field-scale design, bridging the gap between theoretical methods and applied project needs. The framework was validated on the Nisku Formation in Alberta, with site-wide and single-well capacity results aligning closely with published benchmarks, thereby confirming its predictive reliability.

Results show that GI improves overall financial performance, though the effect is insignificant in knowledge-intensive business services and among Asian firms. Strikingly, we uncover a “less is more” dynamic that challenges proportionality assumptions in human capital theory: GI's financial performance benefits are strongest at low levels of formal employee education and decline to negligible effects as education increases. This pattern is most pronounced in low-tech manufacturing, among European firms, and in large organizations.
