ArticleFlow analysis of industrial wood to determine cumulative changes in carbon stocks in wood products
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
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 -
DocumentEvaluation of carbon stocks of domestic wood products to improve carbon sinks in the forest sector
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Harvested Wood Products (HWP) is recognized as a carbon pool in the forest sector, along with biomass, dead wood, litter and soil. There was a debate about which country should include carbon stocks in imported or exported HWP. At the 17th Conference of the Parties in Durban (COP17) in 2011, domestic harvested wood products were accepted as accounted carbon pools and thus have to be reported by all Parties included in Annex I. Although the HWP carbon calculation method related to this has been suggested since the IPCC 2006 guidelines, it could not be calculated due to the lack of HWP statistics data in Korea.
In this study, to estimate the carbon stock and the annual stock changes for each of the HWP categories. Input data on the production of wood products used in the model to estimate carbon emissions and removals from HWP in Korea were acquired from database of the 'Wood utilization survey report' and 'Statistical yearbook of Forestry' in Korea Forest Service. In particular, statistic data on production of sawnwood, wood-based panels and paper and paperboard were obtained for the period 1989–2019. It used the first order decay function with default half-lives of 35, 25 and two years, respectively. For the conversion of wood volume or weight into carbon the default conversion factors and half-lives provided by IPCC guideline. As a result of the calculation, it was estimated that about 0.7 million tCO2 was stored according to the use of domestic wood products in 2019. It is expected that it will be possible to quantify the carbon storage effect of HWP and to activate the use of wood products. Indeed, it could change if life expectancy of HWPs improves into the future. Furthermore, additional mitigation potential may be achieved when substituting emissions-intensive materials.

ArticleThe preservation of natural forests through the establishment of industrial wood production plantations via the new, fast growing Robinia pseudoacacia ‘Turbo Obelisk’ varieties and new cultivation technologies

No results found.After decades of research and development, Silvanus Forestry Ltd. and HungaroPlant Ltd. have successfully propagated the Robinia pseudoacacia ‘Turbo Obelisk’ variety group and developed the necessary cultivation technologies, specifically for intensive industrial wood production plantations. In comparison to the Hungarian and traditional black locust varieties and cultivation technology, industrial wood production plantations established with our variety group and using our cultivation technologies can produce twice as much timber yield and industrial timber yield, considering 15-year rotation periods. These parameters are comparable with the performance of the widespread Eucalyptus and Pinus plantations in the subtropics. Our varieties and cultivation technologies, however, are also usable in subtropical, temperate, as well as tropical climates. The outstanding yields achieved by the ‘Turbo Obelisk’ varieties and the extremely high industrial wood output can provide a significant contribution to the conservation and maintenance of natural ecosystems, whilst the CO2 sequestration per unit area per time is also several times that of natural forests. A particular advantage to emphasize is long term carbon sequestration due to the high percentage of industrial wood yield. Increasing the exceptional tolerance of black locust against drought, pollution and low-quality soils, our varieties are exceptionally suitable for the utilization of marginal agricultural areas, the agricultural utilization of which would otherwise create an economical loss. This can also significantly increase the advancement of less developed regions. In addition to plantation cultivation, it also provides a cost-effective solution for the establishment of protective forest belts, road-side plantings, quicksand fixation and soil renovation. Delicious honey production is also a possible revenue stream. The global exploitation of the research findings has begun, having already successfully established test plantations in China, India, and Pakistan, as well as in several European countries.
