Global efforts have been made to manage tropical forests for timber production and climate change mitigation. This study assessed carbon emission reductions through the improved forest management and the substitution of fossil fuels with wood biomasses under the conventional (CVL) and reduced impact logging (RIL) systems in Southeast Asia between 2000 and 2060. During this period, carbon emissions from logging and deforestation in the region were approximately 10% of carbon emissions from tropical deforestation. By adopting the RIL, 96.6 Tg CO₂ of emissions can be reduced, while producing 35.1 million m³ year⁻¹ of wood products. If woody biomasses are used to substitute the combustion of coal, diesel, or natural gas for bioenergy production, total emission reductions could be 229.9, 215.4, or 207.9 Tg CO₂ annually during the Paris Agreement, respectively. Depending on chosen carbon price, management of natural forests in Southeast Asia could generate about US$2.1–2.3 billion annually over 10 years between 2020 and 2030. Although costs for bioenergy production from wood biomass remain the concern, enabling global policies, emerging sustainability markets, and financial incentives through carbon tax, environmental tax, and energy tax could materialize the sound management of tropical forests for long-term timber production and climate change mitigation.

全球已作出努力，以管理热带森林以生产木材和减缓气候变化。本研究评估了 2000 年至 2060 年东南亚在传统 (CVL) 和减少影响的伐木 (RIL) 系统下通过改进森林管理和用木材生物质替代化石燃料所减少的碳排放量。该地区的森林砍伐约占热带森林砍伐碳排放量的 10%。通过采用 RIL，可以减少96.6 Tg CO ₂的排放量，同时生产 3510 万立方米³年^-1木制品。如果使用木质生物质替代煤炭、柴油或天然气的燃烧来生产生物能源，则在巴黎协定期间，每年的总减排量可能分别为 229.9、215.4 或 207.9 Tg CO ₂。根据选择的碳价格，东南亚天然林的管理在 2020 年至 2030 年的 10 年间每年可产生约 2.1-23 亿美元的收入。通过碳税、环境税和能源税的财政激励措施可以实现热带森林的健全管理，以实现长期木材生产和减缓气候变化。
