Project Vulcan is a collaboration between Purdue University, The Department of Energy and NASA to map the extent of the United States" carbon emissions North American Carbon Program (NACP) to quantify North American fossil fuel carbon dioxide (CO2) emissions at space and time scales much finer than has been achieved in the past using GIS maps [vid]. The purpose of Project Vulcan is to aid in quantification of the North American carbon budget, to support inverse estimation of carbon sources and sinks, and to support the demands posed by the launch of the Orbital Carbon Observatory (OCO) scheduled for 2008/2009. Linked is a state-by-state profile of CO2 emissions.
