Carbon intensity of French shippers

International audienceTo estimate CO2 emitted by a French shipper for the transportation of its shipments, we use the French shipper survey. In this survey, we only have three shipments per shipper and carbon intensity per shipment is highly variable. So the CO2 per shipper was estimated indirectly, with two different approaches: First we set up a typology of the shippers, in 10 types of ‘homogenous’ establishments and estimated in each type an average level of emissions per shipper. In a second approach, carbon intensity per tonne shipped has been modelled, using only the shipper characteristics as explaining variables. Then for each shipper, multiplying this average CO2 emission per tonne per its yearly tonnage shipped gave the amount of emissions for its shipments during that year. The two approaches gave reasonably similar results. On average, a French shipper emits a little more than 620 t per year for the transport of its shipments, and this quantity varies from 78 t for the ‘lower emitter’s type’ up to 4700 t for the ‘upper’ type
