English
This study quantifies carbon removals and emissions across 18 Afrotropical countries (2015-2019). Intact tropical moist forests remove -286 TgC/yr, nearly offsetting land-use emissions of 343 TgC/yr, highlighting the role of conservation policies in reversing national carbon budgets from sources to sinks.

日本のGX文脈において
アフリカ熱帯林の炭素収支の実証データは、日本の森林吸収源評価や国際的なREDD+政策にも示唆を与える。ただし、日本企業の直接的なGX活動への応用は限定的。
In the global GX context
This paper provides robust empirical evidence on African tropical forest carbon dynamics, relevant for global carbon accounting frameworks (e.g., UNFCCC, IPCC). It underscores the critical role of intact forests in offsetting land-use emissions, informing international climate policy.

📄 Abstract（原文）
African tropical moist forests are critical regulators of global carbon cycling, yet their contributions to national carbon budgets remain poorly constrained, impairing effective policy design. Here, we unravel carbon removals and emissions for 18 African tropical countries using multiple approaches over a data-rich period (2015–2019). Across countries, carbon removals (−286 ± 68.4 TgC yr−1) nearly offset land-use change emissions (343.4 ± 100.3 TgC yr−1), with consistent net fluxes between bottom-up and top-down approaches (57.4 ± 121.4 TgC yr−1 versus 99.1 ± 164.5 TgC yr−1). Results vary between countries, with highest removals in intact forests in the Democratic Republic of the Congo (−81.7 ± 64.2 TgC yr−1), lowest land-use change emissions in Gabon (2.6 ± 7.1 TgC yr−1), and highest fossil fuel emissions in Nigeria (31.2 ± 1.6 TgC yr−1). African tropical countries show high carbon removal rates and land-use change emissions but low fossil fuel emissions, contrasting with industrialized countries. (Inter)nationally endorsed conservation policies can reverse national carbon budgets from net sources to sinks. Carbon removals by intact African tropical moist forests nearly offset land-use emissions, underscoring the importance of environmental policies to protect this critical carbon sink, based on synthesized field data, remote-sensing products, and carbon-flux modelling.
