Greenhouse gas emissions and removals from forest land, woodlands, and urban trees in the United States, 1990-2019: Estimates and quantitative uncertainty for individual states

As a signatory to the United Nations Framework Convention on Climate Change (UNFCCC), the United States has been reporting an economy-wide inventory of greenhouse gas (GHG) emissions and removals since the mid-1990s (US EPA 2021). Estimates of GHG emissions and removals from forest land, land converted to and from forest land, woodlands in the grassland category, and urban trees in settlements are compiled by U.S. Department of Agriculture (USDA) Forest Service researchers and are based primarily on national forest inventory (NFI) data collected and maintained by the Forest Inventory and Analysis (FIA) program within the USDA Forest Service. The state-level estimates of GHG emissions and removals provided in this publication are based on the compilation reported in the Land Use, Land-Use Change, and Forestry chapter of the US EPA (2021) submission to the UNFCCC. Included in this package are 15 comma-delimited ASCII text files of estimates (9 of net carbon or CO₂ flux estimates, 2 of carbon stock estimates, 3 of non-CO₂ emissions, and 1 of area estimates of land use and land use change) and 2 files of quantitative uncertainties. All the estimates/uncertainties are the same as those found in Appendix 1 and 2 from “Greenhouse Gas Emissions and Removals from Forest Land, Woodlands, and Urban Trees in the United States, 1990-2019” (Domke et al. 2021).These estimates are being provided in this format to make them more accessible for use in sub-national reporting or further analysis.Appendix 1 and 2 from “Greenhouse Gas Emissions and Removals from Forest Land, Woodlands, and Urban Trees in the United States, 1990-2019” (Domke et al. 2021) are formatted versions of the estimates in this package by state with footnotes that provide table-specific details.
