Carbon Sequestration

First, the units of reporting differ.  The USGS assessment of biologic carbon sequestration reports in TgC/yr (Terragrams of Carbon per year), while the CAR reports in TgCO2-eq/yr (Terragrams of CO2 equivalent per year).  The conv
No, there are currently two others, the Great Plains and Western Biologic Carbon Sequestration Reports. Assessments for Alaska and Hawaii are expected to be completed in 2015. Learn More:
The USGS-authored report, Baseline and Projected Carbon Storage and Greenhouse Gas Fluxes in the Ecosystems of the Eastern United States, was congressionally mandated by the 2007 Energy Independence and Security Act.
This report provides a benchmark for monitoring changes of carbon stocks and greenhouse gas fluxes for the United States.  The data are presented in a user-friendly way to facilitate other studies.
Forests, wetlands and farms in the eastern U.S. store 300 million tons of carbon a year, an amount that exceeds and helps counter-balance yearly U.S. car emissions.
