本研究は、森林の断片化とエッジ露出による炭素損失を考慮した、リスク適応型保護区（RACZ）モデルを開発した。モデルは、森林減少までの距離をリスク指標として、外部圧力と内部抵抗に応じた動的なクレジットゾーンを生成する。低圧力の未開発地域では狭いゾーン、高度に断片化された地域では広範囲なゾーンが得られ、劣化リスクに基づいたクレジット割り当てが可能となる。これにより、自主的炭素市場の環境健全性が向上する。
English
This study develops a Risk-Adaptive Conservation Zone (RACZ) model that integrates spatial degradation risk into carbon crediting. Using distance to deforestation as a proxy, the model generates dynamic zones that adapt to pressure and resistance. Results show small zones in intact landscapes (0.27% area) and large zones in fragmented frontiers (99.4% area), aligning crediting with actual degradation risk and improving environmental integrity for voluntary carbon markets.

日本のGX文脈において
日本ではJ-クレジット制度における森林由来クレジットの算定方法の精緻化に寄与する可能性がある。特に、SSBJや有報でのカーボンクレジット活用が進む中、劣化リスクを考慮したクレジットの信頼性向上は投資家対応にも資する。
In the global GX context
This paper addresses a key gap in voluntary carbon market integrity, aligning with ICVCM core principles. Globally, it provides an ecologically grounded method to improve carbon credit quality, relevant for standards like Verra and Gold Standard, and supports more credible offset claims under corporate net-zero targets.

📄 Abstract（原文）
Fragmentation and edge exposure have caused major, spatially structured carbon losses in once-intact forests globally, yet most carbon methodologies, though central to conservation finance, still rely primarily on projected deforestation and fail to explicitly capture degradation-driven losses spatially. Here, we develop a Risk-Adaptive Conservation Zone (RACZ) model that integrates landscape ecology, spatial gradients of deforestation, and mechanistic edge-effect dynamics to delineate evidence-based carbon crediting zones. Using the distance to the nearest deforestation as a proxy for spatial risk, and incorporating pressure intensity and landscape structure, the model generates a dynamic, project-specific RACZ that adapts to both external pressure and internal resistance. Two tropical, similarly sized areas with contrasting deforestation pressures were tested. The model yielded a small RACZ of 1,150 ha in the intact, low-pressure landscape, concentrated in narrow bands near isolated edges, covering 0.27% of the total area. While for the highly fragmented frontier, RACZ expanded to 337,985 ha, covering 99.4% of the total area and reflecting pervasive, far-reaching degradation risk. These results show that RACZ restricts crediting to genuinely vulnerable areas in intact regions while capturing extensive risk in heavily fragmented frontiers. Therefore, this ecologically grounded approach complements core principles of the Integrity Council for the Voluntary Carbon Market by improving environmental integrity and credibility in carbon accounting through aligning credit zones with spatial degradation risk.
