日本語

このデータセットは、1990年から2018年までの米国農業・林業部門の温室効果ガス（GHG）排出量の推計を提供する。主な排出源は、農地土壌からの亜酸化窒素（N2O）、反芻動物の消化発酵と水田からのメタン（CH4）、家畜排泄物からのCH4とN2Oである。森林や土壌での炭素貯留も考慮し、2018年の純排出量は5,903 MMT CO2換算と報告されている。

English

This dataset provides estimates of greenhouse gas (GHG) emissions from U.S. agriculture and forestry from 1990-2018. Key sources include nitrous oxide from cropland soils, methane from enteric fermentation and rice, and methane and nitrous oxide from managed livestock waste. Carbon sequestration in forests and soils is accounted for, with net emissions of 5,903 MMT CO2 eq in 2018.

日本のGX文脈において

米国固有のデータセットだが、日本の農業GHGインベントリの方法論やデータ形式と比較する際の参考資料となる。日本の農林水産省の排出量推計にも応用可能。

In the global GX context

This dataset is part of the U.S. national GHG inventory, following IPCC guidelines. It provides detailed sectoral data useful for global benchmarking and validation of agricultural emission models.

👥 読者別の含意

🔬研究者:Researchers can use this data for modeling U.S. agricultural emissions or comparing inventory methodologies across countries.

🏢実務担当者:Practitioners involved in agricultural supply chains may use the data to understand emission sources and trends in the U.S.

🏛政策担当者:Policymakers can reference this dataset for understanding how national inventories are constructed and for setting benchmarks.

📄 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) in 2018. 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 zipped, tabulated data from the figures and tables, and maps of the entire 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: Chapter 2 Data.
