Between eight- and nine-tenths of SHV Energy’s footprint is caused by product transport emissions. The rest is split mainly between filling plants and overheads, with a minor fraction to storage.
Product-transport emissions are dominated overwhelmingly by road vehicles,with minor contributions from railcars and barges
Footprints by product type vary, mainly because of the amount of transport required per quantity of LPG sold. As it turns out (Table 1), the average footprint per tonne of cylinder LPG is about 2.5 times that of bulk LPG. This in turn is some 9 times greater than the footprint of wholesale LPG..
In its finest granularity (Figure 4, an even-more-disaggregated version of Figure 1 than Figure 3 is), the relative contributions of primary and secondary transport of bulk LPG and cylinders can be seen more clearly.
CARBON FOOTPRINT, PER BUSINESS TYPE, KG CO2 PER TONNE LPG
|Cylinder||123||From terminal through delivery to retailer. Does not include customer transport, from retailer onward.|
|Bulk||53||From terminal to customer tank.|
|Wholesale||6||Storage and overheads only, assumes no transport – i.e. customer picks up loads at the SHV terminal or depot.|
