日本語
本論文は、再生可能エネルギーPPAとサプライヤーエンゲージメントという2つの企業気候戦略を、GHGプロトコル会計基準との整合性や内部承認プロセス、取引コストなどの実装面から分析。PPAは基準での明確な認識と事業への影響の少なさから成功している一方、サプライヤーエンゲージメントはデータ不一致や高コストによりスコープ3削減に苦戦していることを明らかにした。基準改訂に際し、企業の会計・脱炭素戦略の実態を考慮する必要性を強調。
English
This paper critically examines two corporate climate strategies—renewable energy PPAs and supplier engagement—against GHG Protocol standards and implementation realities. PPAs succeed due to clear accounting recognition and minimal business impact, while supplier engagement struggles with data mismatches and high transaction costs, hindering scope 3 reductions. The findings urge standard setters to integrate practical implementation considerations into major revisions of GHG accounting standards.

日本のGX文脈において
日本ではSSBJ基準の策定が進む中、GHGプロトコルの改訂動向は企業のScope 3算定やSBT認定に直接影響する。本論文は、PPAとサプライヤーエンゲージメントの実務上の課題を具体的に示しており、日本の企業が脱炭素戦略を策定する際の参考となる。特に、サプライヤーエンゲージメントの効果的な実施方法について示唆を与える。
In the global GX context
As the GHG Protocol undergoes major revisions, this paper provides critical implementation insights from corporate practice. It highlights the gap between standard design and real-world accounting challenges, particularly for scope 3 supplier engagement. These findings are directly relevant to global standard setters (e.g., ISSB, GHG Protocol) and companies navigating voluntary carbon accounting and target-setting systems.

📄 Abstract（原文）
The corporate commitment to reducing greenhouse gas (GHG) emissions has gained significant traction, with over 11,000 companies committing to reduce their corporate emissions. This paper critically examines two prevalent corporate climate strategies: renewable energy power purchase agreements (PPAs) and supplier engagement initiatives, highlighting their alignment with existing GHG Protocol accounting standards and company implementation considerations around internal approval processes, business operation impacts, and transaction costs. The analysis reveals that PPAs are successful due to their clear recognition in accounting standards and minimal impact on core business operations. Conversely, supplier engagement programs, despite their endorsement by initiatives like the Science Based Targets Initiative, struggle to deliver scope 3 inventory reductions emissions due to mismatched data and high transaction costs. The paper underscores the necessity for corporate climate standard setters to consider the realities of company accounting and decarbonization strategy practices as standards undergo major revisions. By integrating these implementation considerations, the effectiveness of voluntary GHG emissions accounting and target-setting systems can be improved, ultimately contributing to more significant emission reductions.
