変革の旅：富士通がPACTを活用し、サプライヤーと連携してバリューチェーンの脱炭素化を推進する方法
専門家の視点
富士通のScope 3削減への取り組みは、2040年目標という野心的な物語に対し、PACT導入やCEO主導のトップダウン方針という実体が追いつきつつある構図です。ただし、肝心なのは上流サプライヤーの一次データ取得です。PCF置き換えが進んでいるとはいえ、サプライヤー側のデータ整備能力や協力姿勢に依存するため、実行レイヤーが不明確なままです。ここに物語先走りのズレがあります。実体として、LCAやDesign for Environmentの2000年からの蓄積があり、これは強みですが、外部サプライヤーへの展開は別次元の課題です。隠れた前提は「一次データが標準化される」ことですが、サプライヤーの規模や地域によりデータ品質のばらつきが生じ、その翻訳作業が欠落しています。次の観測点は、この統合システムがいつ全サプライヤーに実装され、どのKPIで進捗を検証するかです。2040年目標は可逆的でなく、一度コミットした以上、データ不足による後退は許されません。結論として、富士通は物語と実体の中間地点におり、今後の成否はサプライヤーを巻き込む実行力と一次データの品質管理にかかっています。

Since its founding in Japan in 1935, Fujitsu has demonstrated its technological expertise and a commitment to innovation. Driven by a strong social responsibility, in 2023 the company accelerated its environmental goals, aiming for zero greenhouse gas emissions across its global value chain by 2040 - a bold leap forward from its 2050 target. Recognizing the importance of accurate, standardized product-level data, in 2023 Fujitsu began implementing the PACT methodology and technical specifications to address Scope 3 emissions and drive meaningful change. Driven by ambitious goals, Fujitsu adopted a top-down approach to supplier engagement, led by the CEO and the Chief Sustainability and Supply Chain Officer, who asked the critical questions: How can Fujitsu achieve its mission of making the world more sustainable by building trust in society through innovation? This proactive mindset highlights the importance of developing efficient, digitally-enabled solutions and fostering collaborative emission reductions with suppliers. Fujitsu’s extensive experience with Life Cycle Assessment (LCA), and a Design for Environment program for its own products since 2000, has
