How relevant is the role of CO₂ from harvested wood products (HWPs) for the Brazilian GHG emission balance? The C stocks and CO₂ emissions and removals from the HWPs in Brazil during 1900–2016 were evaluated using three methodological approaches: stock-change approach (SCA), production approach (PA), and stock-change of domestic origin (SCDOA). Data from the FAO’s FAOSTAT system on production, import and export of semi-finished products (sawnwood, wood-based panels and paper/paperboard) were analyzed, considering distinct land-use activities: deforestation (D), forest management (FM) and afforestation/reforestation (A/R). Two scenarios to evaluate the effect of HWPs from D were evaluated. The C stock in HWPs in 2016 reached 252 Mt C, by SCA. Contributions to C storage historically were higher from sawnwood, but wood-based panels and paper/paperboard have recently outperformed it. A/R is the major activity responsible for C storage in HWPs. The CO₂ removal by HWPs was 521 Mt during 1990–2016, which corresponds to 1.1% of the country’s emissions in the same period. It was concluded that Brazil has become a major producer and wood consumer and that HWPs are allies for a positive C balance and fulfillment of the commitments assumed by the country regarding climate change.

采伐的木材产品（HWP）中的CO ₂对巴西温室气体排放平衡的作用如何？C股和CO ₂使用三种方法对巴西1900-2016年HWP的排放量和清除量进行了评估：存量变化法（SCA），生产方法（PA）和国内来源存量变化（SCDOA）。考虑到不同的土地利用活动，包括毁林（D），森林管理（FM）和林业等，分析了来自粮农组织FAOSTAT系统的有关半成品（锯材，人造板和纸/纸板）生产，进出口的数据。造林/再造林（A / R）。评估了两种评估D的HWP效果的方案。SCA表示，2016年HWP中的C储量达到252 Mt C. 从历史上看，锯材对碳储存的贡献更高，但是人造板和纸/纸板最近的表现要好于锯材。A / R是负责HWP中C存储的主要活动。一氧化碳₂在1990年至2016年期间，HWP的清除量为521 Mt，相当于同期该国排放量的1.1％。得出的结论是，巴西已成为主要的生产国和木材消费国，而HWP是实现正C平衡和履行该国在气候变化方面承担的承诺的盟友。
