Article Title: A Contemporary Carbon Balance for the Northeast Region of the United States
Abstract: Development of regional policies to reduce net emissions of carbon dioxide (CO2) would benefit from the quantification of the major components of the region#39;s carbon balance fossil fuel CO2 emissions and net fluxes between land ecosystems and the atmosphere. Through spatially detailed inventories of fossil fuel CO2 emissions and a terrestrial biogeochemistry model, we produce the first estimate of regional carbon balance for the Northeast United States between 2001 and 2005. Our analysis reveals that the region was a net carbon source of 259 Tg C/yr over this period. Carbon sequestration by land ecosystems across the region, mainly forests, compensated for about 6% of the region#39;s fossil fuel emissions. Actions that reduce fossil fuel CO2 emissions are key to improving the region#39;s carbon balance. Careful management of forested lands will be required to protect their role as a net carbon sink and a provider of important ecosystem services such as water purification, erosion control, wildlife habitat and diversity, and scenic landscapes.
