Dynamics and flow of greenhouse gases in timber forest products
Dynamics and flow of greenhouse gases in timber forest products
Concentrations of greenhouse gases (GHG) in the atmosphere have increased considerably asa result of anthropic activities such as changes in land use, farming, and actions involvingburning fossil fuels. In Brazil, there is considerable action in the global effort to address climatechange, mainly to comply with the international agreements mediated by the United NationsFramework Convention on Climate Change (UNFCCC). Brazil's various commitments includereducing GHG emissions and increasing removal via activities that fix carbon. Forest productionis one of the sectors that can make the greatest contributions to reducing the carbon balance,boosting sequestration by expanding the area and productivity of forest plantations, as well asstimulating greater production of timber goods, which contain around 50% carbon.Meanwhile, information of this kind is still scarce despite the fact that the country is the thirdlargest producer of industrial wood in the world (more than 146 million m 3 ). The lack of thisinformation makes it difficult to guide policies to encourage the use of timber products, as wellas to draft the country's emissions inventories, in which Brazil has reported that the carbonstored in forest products which are being used and/or discarded after use is zero (in otherwords, that there is no accumulation of carbon in the forest products produced). Most of thecountries that are signatories to the Convention already consider this carbon sequestration intheir inventories. However, for Brazil to consider these values, the data and informationgenerated on this topic must be transparent, accessible, and verifiable. For this to occur,research institutions and forest companies must start research and surveys and collect andconsolidate this information. This project will generate data on Brazilian forest production inplanted forests, measuring and clarifying the dynamics and carbon flows of forests and timberproducts while also determining the half-life of use and post-use of the main timber products(solid wood, solid wood panels, reconstituted panels, paper, and cardboard). The followingquestions must be answered: What are the carbon stocks in planted forests? What are thecarbon stocks in timber forest products that are currently in use? What are the carbon flowsfrom timber production, from the stands to manufacture of timber products? What are theaverage half-lives of these products when in use and after use, when they are discarded(decomposition) or recycled/reused? The project is expected to include surveys andconsolidation of data on planted area, production, imports, exports, and shipping of timberproducts with collaboration from forest institutions and companies, decomposition tests indifferent biomes for the 13 forest products that are most produced in the country, andmodeling of carbon flows through case studies representing industrial wood production fromthe forest stands to the final product. At the end of the project, information will be madeavailable on the carbon flows in the production chain of planted forests; this data can not onlybe used to draft Brazil’s reports to the Climate Convention on greenhouse gas emissions, butwill also support decision-making and encourage expanded forest production in the country,along with the products produced in these forests, thus reducing the country's net emissionsvalues.
