日本語

このデータセットは、米国の農業および林業からの温室効果ガス（GHG）排出量と、森林や土壌による炭素吸収量を1990年から2018年までまとめたものです。主な排出源は、農地土壌からの亜酸化窒素、家畜の腸内発酵によるメタン、水田栽培などです。一方、森林や木製品、土壌への炭素貯留により、排出量の一部が相殺されています。このデータは、米国の農業部門のGHG排出量を推定し、不確実性を定量化し、削減可能性を評価することを目的としています。

English

This dataset comprises greenhouse gas (GHG) emissions from U.S. agriculture and forestry from 1990 to 2018, including nitrous oxide from cropland soils, methane from livestock enteric fermentation and rice cultivation, and carbon sequestration in forests and soils. The data provides annual emissions and offsets in MMT CO2 eq., supporting estimation, uncertainty quantification, and mitigation potential assessment for the U.S. agricultural sector.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

米国の農業・林業由来のGHG排出量データは、日本の農業版インベントリ（農林水産省による算定）と比較する上で有用です。ただしSSBJや日本の気候関連開示と直接の関連は薄いですが、Scope 3排出量のうち農業由来の部分（原材料調達など）を理解するための参考データとして活用できます。

In the global GX context

This data inventory provides detailed, long-term U.S. agricultural and forestry GHG emissions and offsets, which can inform global carbon accounting methodologies and serve as a benchmark for other countries. While US-specific, it offers empirical data on agricultural mitigation potential relevant to land-use emissions under TCFD/ISSB frameworks.

📄 Abstract（原文）

The primary greenhouse gas (GHG) sources for agriculture are nitrous oxide (N2O) emissions from cropped and grazed soils, methane (CH4) emissions from ruminant livestock production and rice cultivation, and CH4 and N2O emissions from managed livestock waste. The management of cropped, grazed, and forestland has helped offset GHG emissions by promoting the biological uptake of carbon dioxide (CO2) through the incorporation of carbon into biomass, wood products, and soils, yielding a U.S. net emissions of 5,903 MMT CO2 eq (million metric tonnes of carbon dioxide equivalents). Net emissions equate to total greenhouse gas emissions minus CO2 sequestration in growing forests, wood products, and soils. The report 'U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018' serves to estimate U.S. GHG emissions for the agricultural sector, to quantify uncertainty in emission estimates, and to estimate the potential of agriculture to mitigate U.S. GHG emissions. This dataset contains tabulated data from the figures and tables presented in Chapter 1, Introduction, of the report. Data are presented for Cropland Soils (N2O), Enteric Fermentation (CH4), Managed Livestock Waste (CH4 + N2O), Grazed Lands (CH4 + N2O), Rice Cultivation + Residue Burning (CH4 + N2O), Energy Use, Forests, Harvested Wood, Urban Trees, and Agricultural Soils. Please refer to the report for full descriptions of and notes on the data. Resources in this dataset: Resource Title: Data for Figure 1-3.
