comment Is there a way to integrate my own custom tools into the Processing toolbox in QGIS?
I just found this qa. Did you ever find out what the preferred way is to deploy and register your custom provider with QGIS?

comment Calculating emissions from points in road network using ArcGIS for Desktop?
Does COPERT output emissions levels per vehicle, or per link? Presumably per vehicle would match a mean and per link would match a sum. If you have the choice of either, then as I said above, be guided by your own aims. Either way, don't try comparing on links that have no GPS traces.
