このデータセットは、米国の農業・林業温室効果ガスインベントリ報告書の第2章から、家畜と放牧地の排出量に関する図表データをまとめたものです。牛の消化管内発酵、家畜排泄物管理、放牧地からのメタン・一酸化二窒素排出量を1990～2013年にわたり州別・経年で提供しており、米国農業部門のGHG排出量推定と不確実性評価に利用できます。

English

This dataset compiles tables and figures from Chapter 2 of the U.S. Agriculture and Forestry Greenhouse Gas Inventory (1990–2013), covering emissions from livestock and grazed lands. It provides state-level and time-series data on methane and nitrous oxide from enteric fermentation, manure management, and grazed soils. Useful for understanding the contribution of U.S. livestock to national GHG emissions and for uncertainty analysis.

日本のGX文脈において

米国農業GHGインベントリの詳細データであり、日本の農林水産省や環境省が策定する日本のGHGインベントリ（特に畜産分野）の改善や検証に参考となります。日本の畜産由来メタン排出量推定方法との比較や、不確実性評価手法の導入に活用できるでしょう。

In the global GX context

This U.S. dataset provides a detailed bottom-up inventory of livestock-related GHG emissions (enteric fermentation, manure management) following IPCC guidelines. It serves as a benchmark for countries improving their agricultural inventories, including Japan, and supports global comparison of emission factors and mitigation potentials.

👥 読者別の含意

🔬研究者:Provides granular livestock emission data for the U.S. (1990-2013), useful for developing emission factors, uncertainty analysis, and modeling agricultural GHG trends.

🏢実務担当者:Can be used by agricultural sustainability teams to benchmark U.S. livestock emissions and identify mitigation opportunities such as anaerobic digesters.

🏛政策担当者:Informs national inventory reporting under the UNFCCC and supports design of agricultural mitigation policies by providing emission estimates and reduction potentials.

📄 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 5,803 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: 1990-2013' 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 2, Livestock and Grazed Lands Emissions, of the report. This chapter covers carbon dioxide, methane, and nitrous oxide emissions and removals due to enteric fermentation, animal waste management, and land use for confined and grazed animals. Please refer to the report for full descriptions of and notes on the data. Resources in this dataset: Resource Title: Main Figures, maps, and tables from Chapter 2.
