U.S. Forest GHG Emissions and Removals by State and Ownership, 1990-2024

31 tables of greenhouse gas emissions and removals estimates compiled by USDA Forest Service researchers from Nationwide Forest Inventory data. These data provide 1990-2024 estimates of carbon net flux and 1990-2025 estimates of carbon stocks for the United States and its territories. The estimates are intended for sub-national reporting and further analysis, incorporating new data and methods into the entire time series.

Use Cases

• Tracking state-level forest carbon stock changes based on the 1990-2025 time series
• Comparing GHG emissions and removals across different land ownership types (e.g., National Forests, Tribal lands) based on the provided regional ownership breakdowns
• Incorporating quantitative uncertainty estimates into climate policy models based on the four included uncertainty tables
• Supporting international and national GHG reporting requirements with the annual compilation data

Strengths

• Estimates cover a 34-year time series (1990-2024) for carbon flux
• Data includes results for individual states, regional ownerships, National Forests, and Tribal ownership
• Includes 4 tables of quantitative uncertainties alongside 31 tables of estimates
• Based on primary data from the Forest Inventory and Analysis (FIA) program

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The 0.0 B size listed suggests metadata-only entry; actual data files require verification
