Hello,
I am keen to calculate the fuel emissions of our fleets so that we can see what our footprint looks like. Also There has been talk of changing to diesel instead of petrol vehicles, which apparently works better economically, but how does it stand up environmentally, both on fuel consumption efficiencies and on emissions?? Has anyone got this in a nutshell?
Look forward to hearing from you

For every litre of gasoline used, about 2.4 kg of CO2 are produced; for every litre of diesel fuel, about 2.7 kg of CO2 are produced. Vehicle technology also influences the level of CO2 emissions from a vehicle. For example, a modern diesel vehicle is inherently more fuel-efficient than its gasoline equivalent. And for the same distance travelled, a modern diesel can reduce CO2 emissions by about 20 percent compared with those from a similar gasoline vehicle, even though its per litre CO2 emissions are higher. My understanding of this is that overall CO2 is lower in diesel per km travelled. But diesel has other issues. The best report I know of is: http://www.ucsusa.org/clean_vehicles/fuel_economy/the-diesel-dilemma.html
