2014 data from an IPCC meta-analysis here roughly supports this [1]. 800 gCO2-eq/kWh for coal, 490 for gas, 48 for solar, 12 for nuclear, 11 for wind. To be clear, any non-carbon energy source can decarbonize almost to zero assuming all the lifecycle activities are converted to the non-carbon energy as well. One exception might be hydro with it's potential biogenic methane emissions.
