【 摘 要 】

The forest sector is vital in Europe, providing economic and social benefits to communities. However, this sector is also responsible for some environmental impacts, and it is crucial to ensure that these impacts do not outweigh the benefits described. For this reason, this paper proposes an environmental and economic assessment of three forest wood products -uncoated woodfree paper, natural cork stoppers, and particle boards. The life cycles of these products were modeled using foreground data and a life cycle assessment was conducted to determine the environmental impacts associated with these three life cycles. For the economic assessment, the net present value method was adopted. From the results, it is possible to conclude that the utilization of 1 ha of forest land for 100 years to plant Eucalyptus globulus used in the production of uncoated woodfree paper generates the least environmental impact per euro. A sensitivity analysis was conducted to determine the reliability of the results achieved given the uncer-tainty associated with the data used to model the three life cycles. The same critical impact categories and the same critical life cycle stage (raw materials' extraction) were identified for the three systems under study. Given these similarities, an effort must be made by the forest sector to reduce the impacts of these categories and this life cycle stage. To assist on this task, a set of generic and industry-specific recommendations is provided for companies operating in the forest sector. (c) 2021 Elsevier Ltd. All rights reserved.
