本論文は、企業の自主的な気候コミットメントにおける自然を基盤とした解決策（NbS）の役割を評価する。DICE23モデルに企業の炭素削減需要とNbS・非CO2クレジットの供給コストを組み込み、シナリオ分析を実施。結果、NbSクレジットの活用は2030年までの2℃目標達成確率を高め、コスト削減と排出削減の拡大に寄与することを示した。企業が近中期目標にNbSクレジットを利用することで、エネルギー部門のみの削減に限定した場合と同等の効果が得られる。
English
This paper assesses the role of nature-based solutions (NbS) in voluntary corporate climate commitments by adapting the DICE23 model to include demand for voluntary corporate carbon abatement and supply costs for NbS and non-CO2 credits. Scenario analysis shows that including NbS credits increases the probability of meeting the 2°C target by 2030 by lowering costs and boosting overall mitigation. The study finds that allowing companies to use NbS credits for near-term targets can achieve emission reductions equivalent to tripling corporate commitments limited to energy sector reductions.

日本のGX文脈において
日本ではGX-ETSやカーボン・クレジット市場の設計が進む中、本論文は自然由来クレジットの活用が企業の目標達成とコスト効率に与える定量的な示唆を提供する。特に、SSBJ開示や統合報告書におけるカーボン・オフセットの位置づけを検討する際の参考となる。
In the global GX context
Amid global debates on the integrity of voluntary carbon markets and the role of offsets in corporate net-zero strategies, this paper provides rigorous modeling evidence on how nature-based credits can scale ambition cost-effectively. It directly informs TCFD/ISSB-aligned disclosure on the use of offsets and the CDP questionnaire's treatment of carbon credits.
👥 読者別の含意
🔬研究者:Provides a novel integration of voluntary corporate demand into the DICE integrated assessment model, advancing the literature on carbon credit supply and abatement cost curves.
🏢実務担当者:Corporate sustainability teams can use the findings to justify near-term use of nature-based credits as a cost-effective complement to direct emission reductions.
🏛政策担当者:Policymakers should note that allowing nature-based credits in compliance or voluntary markets can dramatically accelerate near-term mitigation, but careful accounting is needed to ensure environmental integrity.
📄 Abstract（原文）
This paper assesses the role of nature-based solutions as a way to scale sustainability goals, focusing on the use of carbon credits in voluntary corporate climate commitments. To accomplish this, we adapt the DICE23 model by incorporating a demand function for voluntary corporate carbon abatement and by including the costs of supplying nature-based and non-CO2 credits to that market. Through scenario analysis, we examine how likely current and proposed new commitments are to meet 1.5 °C and 2 °C climate thresholds by 2030 and 2050 with and without the use of nature-based carbon credits. We find that the inclusion of nature-based credits would increase the probability of meeting a 2 °C threshold by 2030 by lowering costs and significantly increasing overall mitigation. A key result of this paper is that allowing companies to utilize nature-based credits to deliver on near-term mitigation targets can provide the same number of emission reductions as efforts to expand corporate commitments three-fold, but is limited to reductions in the energy sector alone. Overall, incorporating forests and other nature-based credits into corporate commitments could provide immediate and substantial climate benefits while also supporting people and nature impacts today, enabling companies to better achieve multiple social and sustainability goals simultaneously.
