					Annual Fossil-Fuel CO2 Emissions: Global Stable Carbon Isotopic Signature R.J. Andres, T.A. Boden, and G. Marland Carbon Dioxide Information Analysis Center, Environmental Sciences Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831-6335, U.S.A. DOI: 10.3334/CDIAC/ffe.db1013.2009 Period of Record 1751-2006 Methods The basic data provided in these data files are derived from time series of Global, Regional, and National Fossil-Fuel CO2 Emissions (http://cdiac.ornl.gov/trends/emis/overview_2006.html) and references therein. The data accessible here take these tabular, national, mass-emissions data, multiply them by stable carbon isotopic signature (del 13C) as described in Andres et al. (2000), and calculate the global stable carbon isotopic signature for fossil fuel consumption. Note that the mass-emissions data used here are based on fossil-fuel production estimates since production data are more complete than the fossil-fuel consumption estimates and only a global value is given in this data file (see http://cdiac.ornl.gov/faq.html#Q10 for a description why emission totals based upon production differ from those based upon consumption). Data File Structure These data reside in one file (db1013.global.dat). The first column contains the year and the second column the del 13C signature in per mil units.
