Forest Inventory and Analysis National Program

Carbon in U.S. Forests

In an effort to provide further transparency and consistency in official U.S. forest carbon estimates, the FIA program of the U.S. Forest Service is now providing carbon stock estimates through a selection of our online tools. As we endeavor to improve national consistency of our carbon modeling and estimation procedures, there will be divergences between estimates from older procedures and newer estimates such as provided on this web page. As we progress through this continuous improvement process with our stakeholders, national consistency among carbon reporting tools and improved confidence in carbon estimates will be achieved.
