Adaptation to climate change includes a special category: integrating adaptation and climate change mitigation activities. Executive Order 13514 (pdf, 204 KB) (Federal Leadership in Environmental, Energy, and Economic Performance) in October 2009 required Federal agencies to account for their greenhouse gas emissions in a comprehensive manner, set long-term targets for emissions reductions, and other related activities.

Before the rescinding of that Executive Order in March 2017, USACE had made progress on understanding carbon accounting and storage in our natural lands and waters. One effort was a project to compile data from multiple sources to assess the existing stock and accumulation rates of carbon. This project is described in a report (pdf, 2.25 MB) which describes development of the Carbon Storage Information Portal and the data, methods, and assumptions of this work in an overview of the portal.
