AER calculation

How can we calculate the CO2 emissions of a vessel using the actual fuel consumption? I am looking for a formula based on the different fuels.

the CO2 emissions are calculated by multiplying the Cf of each fuel type with the the fuel consumption of this fuel type.
For example for consumption 500 tons HFO and 100 tons MGO you will get 500x3.114+100x3.206=1877.6 tons CO2


Thank you very much @Iro much appreciated!!!
