日本のGX文脈において

日本でも農業分野のGHGインベントリが整備されているが、本データセットは米国の詳細な方法論を参照できる。日本の農地炭素吸収源評価や削減戦略に示唆を与える可能性がある。

In the global GX context

As a comprehensive inventory from a major agricultural emitter, this dataset offers a benchmark for global agricultural carbon accounting and highlights the role of soil carbon sequestration in offsetting emissions, relevant for international reporting frameworks like IPCC guidelines.

👥 読者別の含意

🔬研究者:Researchers in agricultural GHG accounting can use this dataset for model calibration, uncertainty analysis, and cross-country comparisons.

🏢実務担当者:Corporate sustainability teams in the U.S. agricultural sector may use this data to benchmark their own emissions and understand sector-level trends.

🏛政策担当者:Policymakers can reference this inventory to assess the effectiveness of agricultural mitigation policies and improve national reporting under UNFCCC.

📄 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 3, Cropland Agriculture, of the report. Data are presented for Cropland Soils (N2O), Rice Cultivation + Residue Burning (CH4 + N2O), and Agricultural Soil Carbon and Amendments (CO2). Please refer to the report for full descriptions of and notes on the data. Resources in this dataset: Resource Title: Figures and Map data from Chapter 3.
