Product portfolio analysis towards operationalising science-based targets

日本語

科学的根拠に基づく目標（SBT）を実際の事業に組み込むための、製品ポートフォリオ分析手法を提案。製品ごとの排出量配分や優先順位付けにより、SBT達成への具体的な経路を示すことを目指す。企業の脱炭素戦略立案に有用な示唆を提供する。

English

This paper proposes a product portfolio analysis approach to operationalise science-based targets (SBTs). By allocating carbon budgets to individual products and prioritising decarbonisation efforts, it provides a practical pathway for companies to translate SBT commitments into actionable product-level strategies. The framework supports corporate climate transition planning and SBT implementation.

日本のGX文脈において

日本では温室効果ガス排出量の開示義務化（有報でのサステナビリティ情報）が進み、SBT認定の取得も広がりつつある。本論文の製品ポートフォリオ分析は、日本企業がSBTを実践に移す際の具体的な方法論として参考にできる。特にScope 3の削減を含む製品戦略の立案に役立つ。

In the global GX context

As SBTi validation becomes a common expectation for firms globally, the practical question of how to allocate emissions budgets across a product portfolio remains unresolved. This paper offers a method to link corporate SBTs to product-level decisions, complementing ISSB/TCFD disclosures with actionable internal planning. It also speaks to the growing demand for credible transition plans.
