ArticleFlow analysis of industrial wood to determine cumulative changes in carbon stocks in wood products
XV World Forestry Congress, 2-6 May 2022

No results found.Carbon storage in harvested wood products (HWP) is an internationally recognised measure to mitigate climate change. However, due to lack of reliable and transparent data on production and trade of HWP, carbon accounting in HWP is complicated. The Intergovernmental Panel on Climate Change provides guidelines for reporting countries on how to estimate carbon stocks and their changes in HWP with the use of default or country-specific data as well as accounting methods so that countries can choose an accounting method depending on data availability.The main goal of this work is to analyze the flow of industrial wood in Lithuania and to determine the carbon stocks and their quantitative changes in wood products. We estimated carbon storage in HWP by applying different methods and compared the results. The estimates for Lithuania showed that carbon stock in HWP differs significantly when different methods are applied. The annual carbon inflow and the annual change in carbon stocks are significantly higher (92%) when the analysis of wood flow was used to the accounting of these indicators, compared with statistics data on the production of wood products. This difference was due to the classification of domestically produced raw timber and generated wood waste into country-specific categories of industrial wood products. The increase in the change in carbon stocks was also due to the adjustment of country-specific half-lives. Keywords: Carbon storage, Harvested wood product, Climate change ID:3486859 -
DocumentProduction trend of domestic wood pellet by changes to policy of wood pellet industry

No results found.Korea Wood Pellet Industry started as a public offering business for wood pellet manufacturing facilities by the Korea Forest Service in 2008, and it has been developed in accordance with forest policies such as the supply of wood pellet boilers and the increase in the weight for REC (Renewable Energy Certificates) of ‘Unused Forest Biomass’. Accordingly, we researched into the production trend of domestic wood pellet by changes to policy of wood pellet industry to examine this industry and draw any important implications.
The production of domestic wood pellet had increased from 8,527 tons in 2009 to 67,446 tons in 2017 as a source of heat energy. This is attributed to the increased demand for home use of wood pellets by the supply of wood pellet boiler from the Korea Forest Service.
The production of domestic wood pellet increased to 187,745 tons as a large – scale of manufacturing facilities for wood pellet production were established along with the increase in the weight for REC(Renewable Energy Certificates) of ‘Unused Forest Biomass’ in 2018, and the production of 2020 reached 331,202 tons.
At power generation companies, 139,200 tons of domestic wood pellet was used in 2019 and 299,492 tons in 2020 respectively. The 299,492 tons of domestic wood pellet used in 2020 substitutes 181,088 tons of bituminous coal, and the amount of carbon dioxide reduction amounts to 443,248tCO2-eq
As the use of wood pellet for power generation purposes has drastically increased, it is required to develop stable infrastructure for production and establish a transparent distribution network. Keywords: Climate change ID: 3623092 -
DocumentCarbon storage accounting in Brazilian harvested wood products
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Brazil is one of the world's leading manufacturers of forest products, and 94% of the raw material comes from cultivated forests, mainly of the Pinus and Eucalyptus genera. Harvested wood products (HWP) can be an important carbon pool, based on the estimated carbon stored in the products in use. Thus, as of 2006, the IPCC began to allow the inclusion of these estimates in national inventories of greenhouse gas emissions. However, Brazil only started to consider these removals and carbon emissions by HWP in the 2020 version of the inventory (base year 2016). The primary data of forest production used in this study were obtained from the database of FAO (FAOSTAT) and of IBGE (Brazilian Institute of Geography and Statistics). Only products manufactured with raw material from planted forests were considered. The methodology for calculating the emission and removal of carbon dioxide followed the IPCC guidelines defined in 2006. Three groups of products were considered: sawnwood; wood-based panels; and paper and cardboard. Of the three approaches commonly used to estimate carbon absorption and emission, the most advantageous calculation was the atmospheric flow method, which is based on carbon fluxes rather than stock changes. This approach benefits major wood products exporting countries, such as Brazil. To calculate the estimates, production in the last year (2016) of 13.4 million m3 of sawnwood, 9.63 million m3 of wood panels and 10.3 million tons of paper and cardboard were considered. The estimates obtained indicate that, in 2016 (considering the period 1990-2016), the annual net contribution of forest products estimated by the atmospheric flow approach was the removal of - 50,772 Gg of CO2eq. This removal corresponds to about 3.5% of Brazil's total emissions and 12.8% of LULUCF (Land Use, Land-Use Change and Forestry) activities emissions.
