This database presents existing results on the impact of a load on the total emissions of vehicles between 5 and 40 tons.
The conditions for the inclusion of the results include: we know the mass of the vehicle as well as the mass of the maximum load; the results are from a publicly available publication in English.
Since carbon emissions and fuel consumption levels are arguably proportional, we include both types of observations.
In some cases, the results have been extrapolated under the assumption that carbon emissions and fuel consumption are linearly related to the vehicle mass (i.e. load)
