Hi. My company has an approved SBTi 1.5 degree net zero target.
My base year was calculated using sold volume, however this is not useful for supplier engagement so from 19/20 onwards we have calculated our footprint using delivered volumes.
My concern is that because the base year was calculated using a different type of input data, subsequent movements in the footprint is not a like for like comparison.
I do not have access to historic delivered volume data for my base year, however when I compare the more recent years footprint on sold and delivered volumes, the difference is less than 5%.
Per SBTi, am I required to resubmit an SBTi target with a new base year (i.e. the earliest date that uses delivered volumes) or is it acceptable to keep my base year on sold volume and subsequent years on delivered volumes?
thanks
C
