CarbOn Management Evaluation Tool - Voluntary Reporting
Carbon, in the form of carbon dioxide (CO2) in the atmosphere traps heat. It raises the temperature of the air and contributes to what is known as the "greenhouse effect". To help reduce the amount of carbon in the atmosphere, various ways to store or "sequester" carbon are being investigated. One method is to sequester carbon as organic matter in soils ("humus") and in vegetation. Sequestering carbon helps to reduce the amount of CO2 in the atmosphere.
The CarbOn Management Evaluation Tool - Voluntary Reporting (COMET-VR) is an online management tool that provides a simple and reliable method for estimating changes in soil carbon sequestration, fuel, and fertilizer use resulting from changes in land management. COMET-VR calculates in real time the annual carbon flux using a dynamic Century model simulation.
Users of COMET-VR specify a history of agricultural management practices on one or more parcels of land. The results are presented as ten-year averages of soil carbon sequestration or emissions with associated statistical uncertainty values. Estimates can be used to construct a soil carbon inventory for the 1605(b) program. For more information about the COMET-VR and about the tool visit the COMET-VR website.
