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.

Book (stand-alone)Agriculture, forestry and other land use emissions by sources and removals by sinks
1990-2011 Analysis
2014This report discusses new knowledge on anthropogenic greenhouse gas (GHG) emissions from agriculture, forestry and other land use (AFOLU) activities made available through the new FAOSTAT Emission database. The database is available globally, with country detail, for all agriculture, forestry and land sub-categories available in FAOSTAT and in the Forest Resources Assessment (FRA). GHG emissions are computed from official national activity data and geo-spatial analyses, applying international st andard methodologies of the Intergovernmental Panel on Climate Change (IPCC) to ensure consistency with GHG Inventory processes established under the climate convention. The analysis shows increases in emissions of agriculture (from 4.6 to 5.0 Gt CO2 eq yr-1 in 1990s and 2000s; 5.3 Gt CO2 eq yr-1 in 2011), decreases in deforestation rates (from 4.6 to 3.8 Gt CO2 eq yr-1 in 1990s and 2000s; 3.7 Gt CO2 eq yr-1 in 2010), and decreases in forest sinks, albeit with a reversal since the mid-2000s (f rom -2,9 to -1.9 Gt CO2 eq yr-1 in 1990s and 2000s values; -2.1 Gt CO2 eq yr-1 in 2010). At the same time, the data show that GHG intensity of products (i.e., GHG emissions per unit commodity produced) decreased during 1990-2010, but that if no further mitigation measures and technical efficiency improvements are implemented, future emissions may further increase by up to 30% by 2050. Better information on AFOLU emissions is critical in many developing countries, given the potential to identif y and fund actions that can usefully bridge national food security, resilience, mitigation and development goals into one coherent package. -
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.
