When carbon is removed from forests through harvest, a portion of the harvested carbon is stored in wood products, often for many decades. The United States Forest Service (USFS) and other agencies are interested in accurately accounting for carbon flux associated with harvested wood products (HWP) to meet greenhouse gas monitoring commitments and climate change adaptation and mitigation objectives. National-level forest carbon accounting has been in place for over a decade, but there is an increasing need for accounting for smaller scale administrative units, including USFS National Forest System regions and individual National Forests. This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1909 to 2012 for the USFS Sierra Nevada Bio-Regional Assessment Area (Assessment Area) of the Pacific Southwest Region. For the Assessment Area as a whole, carbon stocks in the HWP pool were increasing at just above 0.5 million megagrams of carbon (MgC) per year beginning in the late 1940's until the early 1990's, with peak cumulative storage to date of 32 million MgC occurring in 1999. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels during the 1960's through 1980's. In the years between the late 1960s and 1990 timber harvest were at high but volatile levels, with high harvests of over 2.5 million ccf (1.8 million MgC) occurring six times during this period, harvest levels from National Forests have since declined to less than 0.7 million ccf (0.5 million MgC) per year, resulting in less carbon entering the HWP pool. Since 2000, emissions from HWP at solid waste disposal sites exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Assessment Area's HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1909 and 2012 exceeds additions of carbon to the HWP pool through harvest. Together with estimates of ecosystem carbon, which are also being developed through the Forest Management Carbon Framework (ForCaMF), regional level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency. Though our emphasis is on the Assessment Area, this accounting method can be applied more broadly at smaller land management units, such as National Forests.

This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1909 to 2012 for the USFS Pacific Southwest Region. For the Pacific Southwest Region as a whole, carbon stocks in the HWP pool were increasing at just below 1 million megagrams of carbon (MgC) per year beginning in the late 1940's until the early 1990's, with peak cumulative storage of 51 million MgC occurring in 1994. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels during the 1960's through 1980's. In the years between the late 1960s and 1990 timber harvest were at high but volatile levels, with high harvests of over 4.3 million ccf (3.2 million MgC) occurring five times during this period, harvest levels from National Forests have since declined to less than 1.1 million ccf (0.8 million MgC) per year, resulting in less carbon entering the HWP pool. Since 1995, emissions from HWP at solid waste disposal sites exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Pacific Southwest Region's HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1909 and 2012 exceeds additions of carbon to the HWP pool through harvest. Together with estimates of ecosystem carbon, which are also being developed through the Forest Management Carbon Framework (ForCaMF), Regional level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency.

This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage 1909 to 2012 for the USFS Southwestern Region, (R3). For the Southwestern Region as a whole, carbon stocks in the HWP pool were growing at an average rate of 0.11 million megagrams of carbon (MgC) per year in a steady increase from its origin until its peak cumulative storage of 9.7 million MgC in 1994. Net positive flux into the HWP pool over this period correlates closely with harvest levels. In the years between the late 1960s and 1989 timber harvest continued at high but notably volatile levels. Within this net growth period, a significant crash which bottomed in 1982 rebounded to new peak of 0.76 million MgC in 1989. Carbon entering the HWP declined steeply thereafter beginning in 1990, when harvests ultimately fell over the next six years to less than 1/10th of their peak levels. Since 1995, emissions from HWP at solid waste disposal sites have exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Southwestern Region's HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1909 and 2012 exceeds additions of carbon to the HWP pool through harvest. Together with estimates of ecosystem carbon, which are also being developed through the Forest Management Carbon Framework (ForCaMF), regional level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency.

This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1909 to 2012 from harvests on the national forests in the USFS Pacific Northwest Region. For the Pacific Northwest Region as a whole, carbon stocks in the HWP pool were increasing at over 1 million megagrams of carbon (MgC) per year between the late 1940's and the early 1990's, with peak cumulative storage between 143 million and 144 million MgC spanning 1992-1995. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels during the 1960's through the 1980's. In the years between the late 1960s and 1990 timber harvest were at high but volatile levels, with harvests exceeding 10.6 million ccf (8 million MgC) twice during this period. Harvest levels from national forests have since declined to less than 1.3 million ccf (1 million MgC) per year, resulting in less carbon entering the HWP pool. Since 1995, emissions from HWP at solid waste disposal sites have exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Pacific Northwest Region's HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1909 and 2012 exceeds additions of carbon to the HWP pool through harvest.

This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1906 to 2012 for the USFS Northern Region. For the Northern Region as a whole, carbon stocks in the HWP pool were increasing at approximately 680,000 megagrams of carbon (MgC) per year in the early1950s through the mid-1990s, with peak cumulative storage of 34.1 million MgC occurring in 1995. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the early1960s through the early 1990s. In the years between the early-1960s and the late 1970s timber harvests were at high levels and experienced moderate variability, with high harvests of over 3.1 million ccf (2.3 million MgC) occurring four times during this period. Harvest levels from National Forests of the Northern Region have since declined to less than 450,000 ccf (340,000 MgC) per year, resulting in less carbon entering the HWP pool. Since 1996, emissions from HWP at solid waste disposal sites exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Northern Region's HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1906 and 2012 exceeds additions of carbon to the HWP pool through harvest. Together with estimates of ecosystem carbon, which are also being developed through the Forest Management Carbon Framework (ForCaMF), regional level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency.

The United States Forest Service (USFS) and other agencies are interested in accurately accounting for carbon flux associated with harvested wood products (HWP) to meet greenhouse gas monitoring commitments and climate change adaptation and mitigation objectives. National-level forest carbon accounting has been in place for over a decade, but there is an increasing need for accounting for smaller scale administrative units, including USFS National Forest System regions and individual National Forests. This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1906 to 2012 for the USFS Rocky Mountain Region. For the Rocky Mountain Region as a whole, carbon stocks in the HWP pool were increasing at approximately 180,000 megagrams of carbon (MgC) per year in the early 1950s through 1995 when carbon stocks plateaued until 2005 followed by the peak cumulative storage to date of 12 million MgC occurring in 2013. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the early1950s through the 1990s. In the years between the mid-1960s and 1990 timber harvests were at high, volatile levels, with high harvests of over 800,000 ccf (600,000 MgC) occurring six times during this period. Harvest levels from National Forests of the Rocky Mountain Region have since declined to less than 470,000 ccf (350,000 MgC) per year, resulting in less carbon entering the HWP pool. With the exceptions of 1998, 2003 and 2004, when emissions from HWP at solid waste disposal sites exceeded additions from harvesting, the Rocky Mountain Region HWP pool has remained in a period of positive net annual stock change because additions of carbon to the HWP pool through harvest exceeds the decay of products harvested between 1906 and 2012. Together with estimates of ecosystem carbon, which are also being developed through the Forest Management Carbon Framework (ForCaMF), regional level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency. Though our emphasis is on the Rocky Mountain Region as a whole, this accounting method can be applied at smaller land management units, such as National Forests.

This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1911 to 2012 for the USFS Southern Region. For the Southern Region as a whole, carbon stocks in the HWP pool were increasing at approximately 400,000 megagrams of carbon (MgC) per year in the late 1950s through the early 1980s, with peak cumulative storage to date of 24.9 million MgC occurring in 2012. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the mid-1950s through the mid-1990s. Harvest levels have been erratic since the late 1990s, yet carbon entering the HWP pool continues to increase. Following 5 years beginning in 2002 when emissions from HWP at solid waste disposal sites exceeded additions from harvesting, the Southern Region HWP pool is now in a period of positive net annual stock change because additions of carbon to the HWP pool through harvest exceeds the decay of products harvested between 1911 and 2012. Together with estimates of ecosystem carbon, which are also being developed through the Forest Management Carbon Framework (ForCaMF), regional level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency. Though our emphasis is on the Southern Region as a whole, this accounting method can be applied more broadly at smaller land management units, such as National Forests.

This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1911 to 2012 for the USFS Eastern Region. For the Eastern Region as a whole, carbon stocks in the HWP pool were increasing steadily from 100,000 megagrams of carbon (MgC) per year in the early 1950s up to 416,000 MgC in 1987, with peak cumulative storage to date of slightly less than 12.7 million MgC occurring in 2013. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the 1980s and 1990s. Harvest levels have declined since the 1990s and have been erratic since the year 2000, yet carbon entering the HWP pool continues to increase. The Eastern Region HWP pool has always been in a state of positive net annual stock change because additions of carbon to the HWP pool through harvest exceeds the decay of products harvested between 1911 and 2012. Together with estimates of ecosystem carbon, which are also being developed through the Forest Management Carbon Framework (ForCaMF), regional level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency.

Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the early1950s through the 1990s. In the years between the mid-1960s and 1990 timber harvests were at high, volatile levels, with high harvests of over 850,000 ccf (620,000 MgC) occurring five times during this period. Harvest levels from National Forests of the Intermountain Region have since declined to less than 200,000 ccf (160,000 MgC) per year, resulting in less carbon entering the HWP pool. Since 2001, emissions from HWP at solid waste disposal sites exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Intermountain Region's HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1911 and 2012 exceeds additions of carbon to the HWP pool through harvest.

This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach to estimate HWP carbon storage from 1910 to 2012 for the USFS Alaska Region. For the Alaska Region as a whole, carbon stocks in the HWP pool were increasing at nearly one-half million megagrams of carbon (MgC) per year in the late 1960s and early 1970s, with peak cumulative storage of 13.5 million MgC occurring in 1996. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the mid-1950s through the 1990s. Harvest levels declined after 1990, resulting in less carbon entering the HWP pool. Since 2005, emissions from HWP at solid waste disposal sites have exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Alaska Region HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1910 and 2012 exceeds additions of carbon to the HWP pool through harvest.

Book excerpt: Global forests capture and store significant amounts of CO2 through photosynthesis. When carbon is removed from forests through harvest, a portion of the harvested carbon is stored in wood products, often for many decades. The United States Forest Service (USFS) and other agencies are interested in accurately accounting for carbon flux associated with harvested wood products (HWP) to meet greenhouse gas monitoring commitments and climate change adaptation and mitigation objectives. National-level forest carbon accounting has been in place for over a decade, but there is an increasing need for accounting at the scale of smaller administrative units, including USFS Regions and individual national forests. This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach and the California Forest Project Protocol (CFPP) to estimate HWP carbon storage from 1906 to 2010 for the USFS Northern Region and its eleven national forests, which span northern Idaho, Montana, South Dakota, and eastern Washington. For the Northern Region as a whole, carbon stocks in the HWP pool were increasing at one million megagrams of carbon (MgC) per year in the mid-1960s, with peak cumulative storage of 28 million MgC occurring in 1995. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the middle of the twentieth century. Harvest levels declined after 1970, resulting in less carbon entering the HWP pool. Since 1995, emissions from HWP at solid waste disposal sites have exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The Northern Region HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1906 and 2010 exceeds additions of carbon to the HWP pool through harvest. Though most individual national forests mirror Regional-level trends in harvest and carbon flux, the timing and magnitude of change differs among forests with some forests departing notably from Regional trends. Together with estimates of ecosystem carbon, Regional and Forest-level estimates of HWP carbon flux can be used to inform management decisions and guide climate change adaptation and mitigation efforts by the agency. Though our emphasis is on national forests in the Northern Region, we provide a framework by which these accounting methods can be applied more broadly at sub-national scales to other regions, land management units, and firms.

Available in PDF, EPUB and Kindle. Book excerpt: Increasing the amount of carbon stored in harvested wood products (HWPs) is an internationally recognized measure to mitigate climate change. Several approaches and tiers of methods may be used to analyze the contribution of HWP in terms of greenhouse gas emissions and removals at a regional and national level. The Intergovernmental Panel on Climate Change (IPCC) provides guidelines on three tiers of methods for estimating annual carbon stock changes in the carbon pool of HWPs. These tiers mostly differ by the availability of input data and the level of HWP aggregation. In this case study for the Czech Republic, we have applied the production approach and alternative tiers of accounting methods, which are described in the IPCC guidelines, including the default method (tier 2) and the most advanced method (tier 3). We used country-specific data and material flow analysis to trace the carbon flow over the entire forest-based sector, including only the domestic harvest and the primary and secondary wood products manufactured within the country. The results of this study show that the carbon stored in the HWP pool could be underestimated if simpler methods and default values nonspecific to the country are applied. At the national level, applying the tier 3 method resulted in a 15.8% higher annual carbon inflow in the pool of HWPs compared to the tier 2 IPCC default method. This means that the advanced method reveals an apparently higher carbon sink in HWPs. A documented increase of carbon storage might bring additional credits to reporting countries, and, more important, it could promote the use of long-life HWPs to mitigate climate change.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimation about carbon stock for domestic lumber in south koreaThe United Nations Intergovernmental Panel on Climate Change (IPCC) selected the BECCS (Bio-energy with Carbon Capture and Storage) process as the best method of climate change to achieve global 1.5u00b0 target most quickly. This study was focused on harvested wood products (HWPs), especially lumber products in South Korea. It is used for various purposes, such as building materials, vessels, pulp, and particle boards. The use of HWPs in domestic forests is a role of carbon storage which stores carbon dioxide in wood products instead of being released back into the atmosphere. In order to achieve the goal of reducing greenhouse gas emissions in Korea, the amount of carbon storage stored by wood products. Therefore, the specific objective of this study is to estimate carbon storage for the HWPs of lumber products in South Korea.
