中国のリチウム電池メーカーEVEエナジー荊門拠点を対象に、電力炭素係数の時間・空間分解能がグリーン電力効果の可視性に与える影響を分析した。屋上太陽光92.30MW・発電104,602.54MWh・削減59,654t-CO2eを確認し、精緻化係数で再計算すると蓄電池セル生産の電力由来炭素強度が5.5214から3.4477kg-CO2e/kWhへ低下、会計粒度が25%改善したと報告する。時間別マッチング、地域別グリッド係数、第三者検証、デジタル製品記録の役割を整理し、輸出コンプライアンス準備への示唆を与える。

Using EVE Energy's Jingmen base as a case, this study examines how the temporal and spatial resolution of electricity carbon factors affects the visibility of green electricity benefits for lithium-battery exporters. Rooftop PV of 92.30 MW generating 104,602.54 MWh yields an estimated 59,654 t CO2e reduction; refined factors lower the electricity-related carbon intensity of cell production from 5.5214 to 3.4477 kg CO2e/kWh, improving accounting granularity by 25%. It distinguishes accounting visibility from verified reductions and highlights hourly matching, localized grid factors, third-party verification, and digital product records for export compliance readiness.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
製品別炭素フットプリントと電力由来排出の可視化は、EU電池規則やCBAM対応、SSBJ/Scope3開示を進める日本企業にとって供給網データ整備の参考になる。時間別・地域別係数の精緻化は国内の蓄電池・自動車サプライヤーの実務課題と直結する。
In the global GX context
As product-level carbon footprint and lifecycle traceability rules tighten under the EU Battery Regulation and CBAM, this case shows how granular electricity carbon factors and hourly matching improve auditability of Scope 2 and product emissions. It offers a concrete template for exporters preparing for disclosure and verification requirements.

📄 Abstract（原文）
Against the backdrop of increasing regulatory attention to lifecycle emissions and product-level traceability, lithium-ion battery exporters need credible carbon footprint information. This study takes the Jingmen base of EVE Energy as a case to analyze how the temporal and spatial resolution of electricity carbon factors affects the visibility of green electricity benefits. The study comprehensively reviews the rooftop photovoltaic and energy storage investments, Hubei grid factors, and third-party verification records reported in the case. The case report shows that the rooftop photovoltaic installed capacity is 92.30 MW, with electricity generation of 104,602.54 MWh, and an estimated emission reduction of 59,654 t CO₂e; after recalculation using refined factors, the carbon emission intensity associated with electricity consumption for energy storage cell production changes from 5.5214 to 3.4477 kg CO₂e/kWh, and the accounting granularity is reported to have improved by 25%. The analysis distinguishes the visibility of carbon accounting from independently verified actual emission reductions, and summarizes the roles of hourly matching, localized grid factors, third-party verification, and digital product records. These measures help improve the auditability of electricity-related performance and enhance export compliance readiness, providing a reference for carbon management optimization for lithium battery exporters.
