本論文は、排出削減と二酸化炭素除去（CDR）を組み合わせた緩和戦略が、温暖化応答を短期的および長期的に中和するための会計アプローチを提案する。持続的温暖化中和という概念を用いて、排出と緩和の気候影響を全球平均気温応答という単一指標に変換する。企業がネットゼロ目標を達成するためのポートフォリオ設計手法を提示する。
English
This paper proposes an accounting approach for neutralizing the warming response to emissions by combining emissions abatement and carbon dioxide removal (CDR) with varying durability. The approach translates climate impacts into a single metric: continuous global mean surface temperature response. It aligns emission compensation claims with global temperature stabilization goals and provides a method for organizations to design mitigation portfolios.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJや有報でのネットゼロ開示が進む中、本提案は排出補償の時間軸を考慮した会計手法として重要。特にCDR（DACCSやBECCS）の導入検討やカーボンクレジットの質的評価に示唆を与える。
In the global GX context
Globally, as companies face pressure to substantiate net-zero claims under frameworks like SBTi and the Oxford Principles, this warming neutralization approach offers a rigorous method to address both near-term and long-term climate impacts, strengthening the credibility of emission compensation claims.
👥 読者別の含意
🔬研究者:This paper provides a novel framework for accounting for the time-dynamic climate impacts of mitigation strategies, which could inform future carbon accounting standards and net-zero modeling.
🏢実務担当者:Corporate sustainability teams can use the proposed warming neutralization method to design and communicate credible mitigation portfolios that align with net-zero targets and avoid greenwashing accusations.
🏛政策担当者:Policymakers should consider this approach when developing regulations for carbon offsets and net-zero claims, as it explicitly addresses the temporal dimensions of emission compensation.
📄 Abstract（原文）
Both emissions abatement and carbon dioxide removal will play a critical role in achieving a global net-zero scenario under which temperatures are stabilized. In the near term, organizations pursuing their own net-zero targets may use superpollutant emission abatement and both shorter- and longer-durability carbon dioxide removal to compensate for their remaining emissions. Because these mitigation strategies have climate impacts across distinct timescales, they can serve as powerful and complementary tools to address both the acute near-term and long-term equilibrium warming response to emissions. However, the distinct timescales of these impacts mean that, if accounting approaches are to ensure emissions remain compensated across all time horizons, they must explicitly evaluate the impact of each mitigation strategy as a function of time. We propose one such accounting approach, based on sustained warming neutralization. By translating the climate impacts of both emissions and mitigation into a single metric - the continuous global mean surface temperature response - the approach aims to ensure the neutralization of the warming response to an emission in both the near- and long-term. Ultimately, this warming neutralization approach structurally aligns emission compensation claims with global goals for temperature stabilization. We then introduce a specific method through which an organization can use the approach to design mitigation portfolios to compensate for its emissions. We invite future work to consider how the warming neutralization approach could be operationalized in a way that ensures impactful, accessible, and widely recognized emissions claims.
