English

This dataset compiles tabulated data from Chapter 4 of the U.S. Agriculture and Forestry Greenhouse Gas Inventory (1990-2013), focusing on forest carbon stocks and stock changes. It provides annualized estimates by ownership, region, and carbon pool with uncertainty intervals, supporting national greenhouse gas accounting.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

米国森林炭素データは日本の森林吸収源報告手法の参考となる。ただしSSBJや有報とは直接関係せず、国際比較研究向け。

In the global GX context

While specific to the U.S., this dataset exemplifies detailed forest carbon accounting approaches that are relevant to global carbon stock assessments under the Paris Agreement. It can inform methodologies for countries developing their own forestry sector GHG inventories.

👥 読者別の含意

🔬研究者:Useful for benchmarking forest carbon stock change estimates and understanding uncertainty quantification in national inventories.

🏛政策担当者:Provides a model for how forest carbon sinks can be quantified in national greenhouse gas inventories, including uncertainty intervals.

📄 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 4, Carbon Stocks & Stock Changes in U.S. Forests, of the report. Data are presented for above and below-ground carbon stocks and stock changes. Please refer to the report for full descriptions of and notes on the data.
