I dont' believe you'll get a direct correlation from fuel consumption to pollution emission. You'll need to include information on the process (engine type, partial vs. full load etc.). If you know the engine, you may obtain data on emission and fuel consumption for several points of operation from the manufacturer. Use this data to get a correlation for your annual emission.

The emissions of the pollutants will vary with the type of combustion  and the type of vehicle. Older vehicles are prone to pollute more. In my country there are periodic reports where these factors of emissions by vehicle, fuel and pollutant.

Daniela, are these reports in the public domain and could you give a reference where we could obtain a copy, please?

Hi thanks for your reply. Im trying to model atmospheric dispersion modelling from Chimney. I'm using AERMOD view. Problem is that in gaussian dispersion modelling, We need to provide emission rate of the pollutant. We are provided only with data of fuel consumption rate. I'm not sure how to compute emission rate(g/s) for each pollutant.

I would say you can't. without knowing details of the process (turbine, diesel engine, whatever..) your emission estimate could be wrong by orders of magnitude. Even knowing it is a diesel engine, is not sufficient. If you look at the development of vehicle emission standards in Europe, NOx limits for diesel engines were reduced from 8 g/kWh to 0.4 g/kWh between 1992 and 2013, while engine efficiency may be improved a little bit. I would expect a similar development for stationary engines.
