The factor for CO2g/kWh in 2017 is lower: between 6.0 and 7.3, depending on what exactly is measured.[1]

However, the absolute numbers for Germany are declining fast as renewable energies are taking hold:[2]

  2017: 485
  2018: 471
  2019: 408 (preliminary)
  2020: 366 (estimated)
  

(In a hurry, could not find newer numbers for France.)

If one looks at the CO2 emissions per capita the gap is not so large. I could not find any new numbers for this either, but in 2018 the values of CO2 emissions in metric tons per capita were as follows:[3]

  France 5.0 
  Germany 9.1  
  For comparison: United States 16.1 
  

If one looks at the timelines, the gap between France in Germany seems to close more or less fast/slowly everywhere.
