This database contains estimates of the annual mean global value of delta 13C of CO2 emissions from fossil-fuel consumption and cement manufacture for 1751-2014. These estimates of the carbon isotopic signature account for the changing mix of coal, petroleum, and natural gas being consumed and for the changing mix of petroleum from various producing areas with characteristic isotopic signatures. This time series of fossil-fuel delta 13C signature provides an additional constraint for balancing the sources and sinks of the global carbon cycle and complements the atmospheric delta 13C measurements that are used to partition the uptake of fossil carbon emissions among the ocean, atmosphere, and terrestrial biosphere reservoirs.
