本研究は、二酸化炭素除去戦略としての植林・再植林（A/R）によるアルベド効果の初の体系的な概要を提供する。既存の科学文献をレビューした結果、A/Rは一般的にアルベドを減少させ、炭素隔離による冷却効果を部分的に相殺する温暖化をもたらすことが判明した。結果は、A/Rの正味の気候影響を完全に評価するためには、より詳細なサイト固有の研究の必要性を強調している。
English
This study provides the first systematic overview of the albedo effect from afforestation and reforestation (A/R) as a carbon dioxide removal strategy. The authors review existing scientific literature and find that A/R generally reduces albedo, leading to warming that partially offsets the cooling from carbon sequestration. The results highlight the need for more detailed, site-specific research to fully assess the net climate impact of A/R.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
この系統的レビューは、自然ベースのソリューションに関するグローバルなGXの議論において重要であり、日本の森林吸収源政策においても、炭素以外の気候影響を考慮する必要性を示唆する。
In the global GX context
This systematic review is crucial for global GX discussions on nature-based solutions, as it underscores the importance of accounting for non-CO2 climatic effects (especially albedo) when designing and crediting afforestation projects under frameworks like Article 6 of the Paris Agreement or voluntary carbon markets.

📄 Abstract（原文）
Abstract Carbon dioxide removal (CDR) will play a crucial role in mitigating climate change and achieving net zero CO 2 emissions. As one technique of the CDR portfolio, afforestation and reforestation (A/R) is heavily relied on in both climate change mitigation scenarios and policy strategies. However, beyond CO 2 sequestration, A/R can have side effects that may affect its effectiveness in drawing global temperatures down, which is the ultimate aim of CDR. In our study, we focus on A/R’s impact on the Earth’s albedo. Here, we provide the first systematic overview of the albedo effect. We review and synthesize the existing evidence in the scientific literature and analyze patterns of the albedo effect. The results show a heterogeneous literature landscape with large areas of underrepresentation. Our collected data shows a reduced albedo in almost all cases, and different temperature responses on different scales. Considering the data heterogeneity and availability, our research findings show that more detailed research is needed to comprehensively assess the albedo impact of A/R and consider fine-grained site-specific factors such as topography.
