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…
