炭素排出削減政策下で資本制約に直面する再製造企業を対象に、炭素枠担保融資（CQPF）の効果を二期間の生産・削減モデルで分析。自己資本不足時にはCQPFが排出削減と利益を向上させる一方、排出量増加の副作用も示す。研究開発投資は累積効果を持ち、第二期の削減効果が第一期より顕著で、排出浄化よりも高い削減と利益をもたらす可能性がある。
English
This paper models two-period production and carbon abatement decisions for remanufacturing firms under capital constraints, comparing carbon quota pledge financing (CQPF) with self-financing. Results show CQPF boosts abatement and profits when capital is scarce, but may increase total emissions. R&D investment exhibits cumulative effects, yielding stronger second-period abatement and potentially higher profits than emission purification.

日本のGX文脈において
日本ではカーボン・クレジット市場や排出量取引の活用が進む中、炭素枠を担保にした融資は中小企業の資金調達手段として注目される。本モデルは、資本制約下の企業が排出削減投資を行う際の資金調達設計に示唆を与え、GX経済移転債やトランジション・ファイナンスの実務にも関連する。
In the global GX context
Globally, carbon pricing mechanisms and transition finance are expanding, and this paper offers a modeling framework for using carbon allowances as collateral, relevant to ISSB-aligned disclosure and transition finance. It highlights trade-offs between financing-driven abatement and emission increases, informing policy design for carbon markets and green lending.

📄 Abstract（原文）
Due to the severe environmental pollution problem and the guidance of carbon emission reduction (CER) policies by the government, firms conduct carbon abatement investment (CAI) through different CER paths to realize low carbon production, in which capital constraint may be a significant factor that cannot be ignored. Thus, to rational use the carbon quota allocated, carbon quota pledge (CQP) acts as an effective financing method in supporting CERs. In this paper, based on carbon cap-and-trade mechanism, we establish two two-period manufacturing/ remanufacturing production decision models to contrastively evaluate the effectiveness of capital constraint and carbon quota pledge financing (CQPF) on the optimal production, CER and profits of firms under two CAI methods consisting of carbon emission purification and R&D investment. Our results indicate that CQPF more effectively enhance CERs and increase profits of firms when the self-owned capital is shortage, whereas it contributes to the increase in carbon emissions simultaneously. We also find that R&D investment has a cumulative effect, namely, the CER effect of the second period is more obvious than that of the first period, and the CERs and expected profits may even be higher than the case of carbon emission purification.
