本論文は、米国における森林地、林地、都市樹木からのGHG排出・除去量を1990～2021年にわたって推定し、州・所有グループ・国有林地域別に集計したものである。米国環境保護庁のUNFCCC提出報告書に基づき、18の推定表と2つの不確実性表を提供する。データはUSDA森林局の国家森林インベントリに基づく。
English
This paper provides detailed estimates of greenhouse gas emissions and removals from forest land, woodlands, and urban trees in the United States from 1990 to 2021, broken down by state, ownership group, and National Forest System region. It includes 18 tables of estimates and 2 tables of quantitative uncertainties, based on the U.S. EPA submission to the UNFCCC, using USDA Forest Service National Forest Inventory data.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、SSBJやJ-クレジット制度における森林炭素吸収源の評価が重要視されている。本論文は、USDA森林局が実施する詳細な森林インベントリと不確実性評価の手法を示しており、日本の森林吸収源算定の精度向上や国際報告への応用に参考となる。
In the global GX context
This paper illustrates a rigorous approach to national forest GHG accounting with uncertainty quantification, relevant for countries implementing UNFCCC reporting and for global carbon accounting standards such as the IPCC Guidelines. It provides a model for integrating ground-based inventory data into economy-wide greenhouse gas inventories.
👥 読者別の含意
🔬研究者:Forest carbon inventory methodology and uncertainty quantification for national-scale GHG accounting.
🏢実務担当者:Relevant for forestry professionals involved in carbon offset projects or national reporting; provides data sources and estimation framework.
🏛政策担当者:Insights into how the U.S. complies with UNFCCC reporting for LULUCF, useful for designing national inventory 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. Included in this package are 18 tables of estimates and 2 tables of quantitative uncertainties.
