コンゴ盆地の6か国における工業的な伐採コンセッションを対象に、衛星データを用いて2020～2024年の年間伐採量と炭素排出量を推定。インパクトの低い伐採手法に切り替えることで排出量を35～58%削減でき、年間3億～4億8900万ドルの気候資金を生み出す可能性がある。推定値は国家統計や従来のサンプリングベースの推定と大きく異なり、より正確なデータを提供する。
English
Using satellite data, this study estimates annual timber harvest volumes and carbon emissions from industrial logging concessions in six Congo Basin countries for 2020-2024. It finds that reduced-impact logging could cut emissions by 35-58%, generating $309-489 million per year in climate financing. The estimates differ significantly from national statistics and previous sample-based accounting, providing more accurate, spatially-explicit data to support sustainability assessment and climate mitigation.

日本のGX文脈において
この研究は、熱帯林の伐採による炭素排出量の推定手法を提供しており、日本の林業や海外での持続可能な森林管理（REDD+など）にも応用可能。特に、日本の企業がサプライチェーンにおける森林由来の排出削減を目指す際の参考となる。
In the global GX context
This paper provides a method for estimating carbon emissions from tropical logging, relevant to global climate accounting frameworks like the IPCC guidelines and REDD+. The findings highlight discrepancies with national statistics, emphasizing the need for satellite-based monitoring in carbon markets and climate finance mechanisms such as the Paris Agreement.
👥 読者別の含意
🔬研究者:This study offers a scalable, satellite-based method for estimating harvest volumes and carbon emissions, which can be applied to other tropical forest regions.
🏢実務担当者:Companies involved in tropical timber supply chains can use these estimates to quantify and reduce their Scope 3 emissions from deforestation.
🏛政策担当者:The paper provides evidence for using satellite monitoring to improve national forest carbon accounting and to design climate financing mechanisms for reduced-impact logging.
📄 Abstract（原文）
Abstract Selective logging is widespread in tropical forests, yet its extent, intensities, and impacts are poorly understood. Here we developed estimates of annual timber harvest volumes, carbon emissions, and potential emissions reductions for 2020–2024 for industrial logging concessions in six Congo Basin countries. Using 62 harvest observations, we calibrated a model linking logging road development and forest disturbance detection data to harvest volumes, generating predictions at multiple spatial scales. Regional harvests averaged 14.7 M cubic meters per year and produced emissions of 87.5 teragrams carbon dioxide per year. Reduced-impact logging practices could cut emissions by 35–58%, generating $309–489 M per year in climate financing. Our harvest estimates differ from national statistics (125% higher for Gabon, 81% lower for Democratic Republic of the Congo) and our road development emissions estimates differ from previous sample-based accounting (73% lower for region). These timely, spatially-explicit data support sustainability assessment, regulatory compliance, certification efforts, and climate mitigation strategies, and our methods are broadly applicable to tropical forests with selective logging.
