This review examines lifecycle carbon emission characteristics and mitigation pathways of smart energy meters using LCA. Use-stage electricity accounts for 70.1-88.5% of lifecycle GWP, but dominance varies with electricity mix, service life…

Yanxun Gu, Kun Yang, Jian Cao +1

This review critiques the limitations of national-average grid carbon emission factors (CEFs) that ignore spatial and temporal heterogeneity, and evaluates the emerging paradigm of grid hierarchical and zonal division. It proposes an integr…

A review of 102 studies finds that 56±25% of soil organic carbon in blue carbon ecosystems is allochthonous particulate organic carbon (POC). Including it in carbon accounting risks overestimation and double-counting, but its role in stabil…

Miller, Gregory J., Rouille d'Orfeuil, Benjamin, Shi, Wenbo

The Open Grid Emissions Initiative provides publicly accessible hourly grid emissions data for the U.S., built on EPA's eGRID with improved data quality and granularity. The 2025 early release includes plant and subplant-level data only, wi…

Decarbonizing construction requires whole-life carbon accounting beyond operational energy. This critical review interrogates evidence for sustainable materials and circular strategies, finding that claimed benefits often rely on lab-scale …

Rick Hagenaars, Arjan de Koning, Reinout Heijungs +2

Drug-level carbon footprints vary significantly across countries, but data scarcity hinders estimation. This paper develops a hybrid LCA framework combining drug-level inventories with international trade statistics and uncertainty assessme…

This study exploits the June 2022 methodology revision for non-domestic EPCs in England and Wales as a natural experiment, showing that grid decarbonisation can improve carbon-weighted ratings without building improvements. 80.5% of reasses…

Yating Zhang, Dustin T. Cook, S. Sattar +3

This paper proposes a hybrid method combining unit process analysis and economic input-output analysis to quantify embodied carbon emissions from post-earthquake building repair and functional loss. It accounts for repair materials, transpo…
