Carbon Dioxide Information Analysis Center

The Carbon Dioxide Information Analysis Center (CDIAC), located at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL), is the primary climate change data and information analysis center for DOE. CDIAC is supported by DOE's Climate and Environmental Sciences Division within the Office of Biological and Environmental Research (BER).

CDIAC's data holdings include estimates of carbon dioxide emissions from fossil-fuel consumption and land-use changes; records of atmospheric concentrations of carbon dioxide and other radiatively active trace gases; carbon cycle and terrestrial carbon management datasets and analyses; and global/regional climate data and time series.
