本レビューは、LCAフレームワークに基づき、スマートメーターのライフサイクル炭素排出特性と削減経路を検討する。使用段階の電力がライフサイクルGWPの70.1～88.5%を占めるが、電力構成や寿命、製品構成、評価境界によって支配段階は変わる。削減策として、動作電力・通信需要の削減、PCBや電子部品の内包炭素低減、寿命延長、廃棄回収改善を提案。標準化された算定ルールと部品レベルデータの必要性を指摘。

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, and boundaries. Mitigation priorities include reducing operating power, lowering embodied carbon of PCBs and components, extending service life, and improving recovery. Standardized accounting rules and component-level data are needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではスマートメーターの普及が進み、電力系統の脱炭素化に寄与する一方、その製造・運用・廃棄に伴う排出の可視化が重要。本レビューは、日本企業がサプライチェーン排出量（Scope 3）を算定する際の基礎データや方法論の参考となる。また、SSBJ開示に対応するための製品カーボンフットプリント算定にも示唆を与える。
In the global GX context
Globally, smart meters are key to grid decarbonization, but their own lifecycle emissions are often overlooked. This review provides a systematic LCA framework and identifies hotspots, supporting companies in Scope 3 accounting and product carbon footprint disclosure under ISSB/CSRD. It highlights the need for standardized rules and component-level data, relevant for global supply chain transparency.

📄 Abstract（原文）
Smart energy meters are widely deployed electronic terminals. Under large-scale deployment and long-term operation, their life cycle carbon emissions can become significant. Based on the life cycle assessment (LCA) framework, this review critically examines the life cycle carbon-emission characteristics and mitigation pathways of smart energy meters. Particular attention is given to system boundaries, data requirements, stage-specific hotspots, and cross-stage trade-offs. Representative studies indicate that use-stage electricity can account for approximately 70.1–88.5% oflife cyclee GWP. However, the dominant stage varies with electricity mix, service life, product configuration, and assessment boundary. Accordingly, mitigation priorities should include reducing operating power and communication demand, lowering the embodied carbon of printed circuit boards (PCBs), printed circuit board assemblies (PCBAs), and key electronic components, extending reliable service life, and improving end-of-life recovery. This review also distinguishes direct meter-level emissions from indirect system-level benefits. Key future needs include standardized accounting rules, component-level carbon data, anlife cyclele-based mitigation assessment.
