This study analyses GHG emissions from 2422 coal-fired power plants (6525 units) with a total installed capacity of 2125 GW. Using a bottom-up approach, CO₂, CH₄, and N₂O emissions are calculated based on individual plant characteristics, including capacity, coal type, and load factor. The findings indicate a predominance of subcritical coal-fired power plants, the least efficient, with specific emissions of 6.95 MtCO₂eq/GW. Bituminous coal is the largest emission source, accounting for 41 % of global GHG emissions from coal power. Significant regional disparities were identified with over 70 % of global coal power emissions originating from China, India, and the United States. China alone accounts for more than half (52 %) of total emissions. Special attention is given to power plants using unknown types of coal that are responsible for 31 % of emissions, highlighting substantial gaps in monitoring systems. The results indicate that while advanced coal technologies, including ultra-supercritical units and carbon capture and storage (CCS), can reduce emissions to some extent, their mitigation potential within the existing coal fleet remains limited relative to the goals of the Paris Agreement.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"228 ","pages":"Article 108808"},"PeriodicalIF":10.9,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146079309","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}

In the deployment of CCS, it is important to identify an optimal network to allocate CO₂ between CO₂ sources and sinks. However, research on source-sink matching has been limited mostly to mathematical programming approaches with inherently limited interpretability to plan CCS involving different emission sectors and different storage reservoirs. Alternative techniques that may offer some interpretability advantages have not been explored as thoroughly. To address this research gap, this study introduces an integrated framework that synergistically combines Carbon Storage Composite Curves (CSCC) with Orthogonal Experimental Design (OED). This CSCC-OED framework is designed for the interpretable, multi-sectoral optimization of CCS infrastructure planning. It could coordinate the dynamic matching of CO₂ source-sink over a multi-decade planning horizon, while addressing constraints of storage capacity, operational timelines, and reservoir availability. The CSCC framework quantifies three critical metrics: additional storage requirement, total storage capacity, and excess capacity. Finally, global sensitivity analysis is performed to investigate the effect of parameters on the CCS deployment based on the deployment factors identified by OED method. Results of the case study indicate that the start time of CO₂ reservoir is the most statistically significant factor. 10 Gt of CO₂ could be stored via three reservoirs commencing operation in 2025, which contributes to 81.63% of the sectoral emission reduction target. Furthermore, scenarios involving policy-, technology-, and economy-driven CCS pathways are analyzed. This work establishes a systematic decision-support tool for CCS infrastructure planning, emphasizing the criticality of coordinated multi-sectoral strategies and early reservoir deployment to meet carbon neutrality goals.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"228 ","pages":"Article 108785"},"PeriodicalIF":10.9,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145961850","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 uses Material Flow Analysis and Life Cycle Assessment to investigate the potential of ambitious circularity measures and climate-compliant energy targets to cut emissions and conserve resources across the European Union’s steel supply chain, while addressing steel quality challenges. Results show that circularity strategies complement each other, reducing production quantities and increasing recycled content.

Here, we conduct a meta-analysis of 160 energy-use data points from 15 peer-reviewed studies, spanning 20 material types and three machine types. We find a mean SEC of 3.13 kWh/kg, which is 2 to 2.5 times higher than default values in commonly used databases, and observe that acrylonitrile butadiene styrene (ABS) exhibits a distinct high-SEC cluster. A mixed-effects meta-regression further identifies material theoretical heat energy, machine type, and injection utilization as the primary drivers of variability, collectively explaining 74.2 % of the observed variance. Selecting polymers with low theoretical heat energy and maximizing injection utilization can reduce SEC by up to 50 % across machine types.
