📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも森林吸収源の報告が重要であり、本データセットはサブナショナルレベルでの炭素インベントリ構築手法の参考となる。特に所有別・地域別の詳細な推定は、日本の県別報告や森林管理政策に示唆を与える。
In the global GX context
This dataset exemplifies how the U.S. reports forest carbon at subnational scales, relevant for countries like Japan that need to enhance their LULUCF reporting under UNFCCC. The quantitative uncertainty analysis is a methodological contribution to global carbon accounting standards.
👥 読者別の含意
🔬研究者:Provides a comprehensive reference for forest carbon estimation methods and uncertainty quantification at subnational level.
🏛政策担当者:Illustrates how to disaggregate national forest carbon reports by ownership and region, useful for designing domestic carbon accounting systems.
📄 Abstract（原文）
As a signatory to the United Nations Framework Convention on Climate Change (UNFCCC), the United States has been reporting an economy-wide inventory of greenhouse gas (GHG) emissions and removals since the mid-1990s. Estimates of GHG emissions and removals from forest land, woodlands in the grassland category, and urban trees in settlements are compiled by U.S. Department of Agriculture (USDA) Forest Service researchers and are based primarily on National Forest Inventory (NFI) data collected and maintained by the Forest Inventory and Analysis (FIA) program within the USDA Forest Service. The estimates of GHG emissions and removals provided in this publication are based on the compilation reported in the Land Use, Land-Use Change, and Forestry chapter of the U.S. Environmental Protection Agency (EPA) submission to the UNFCCC. These data include 1990 to 2022 estimates of carbon net flux and 1990 to 2023 estimates of carbon stocks and land use/land use change area from the United States, American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. Included in this data publication are 21 tables of estimates and 2 tables of quantitative uncertainties, which provide results by individual states, regional ownerships, National Forests, and Tribal Ownership.
