It is based on a historical baseline from scope I emissions and estimated projections towards the future, shown in the figure and tables below. It should be noted that these numbers are updated when more information on our emission factors becomes available.
Scope I emissions for Heerema include emissions due to combustion of fuel from the Sleipnir, Thialf, Balder, Aegir, Kolga and Bylgia, as well as gas usage of all Heerema offices and Flushing yard. These are currently 202,303 [metric tons]. Methane slip from Sleipnir is not (yet) included in these figures. The exact impact is now being verified, and expected to be in the order of 15.000 [metric tons].
Scope II emissions are emissions from electricity use in all Heerema locations. These locations are the Flushing Yard, Houston-, London- and Singapore office. All their emissions combined are estimated at 2,367 [metric tons] at the moment, but are under review and are subject to change. As can be seen however, scope II emissions are orders of magnitude smaller than Scope I emissions and will not significantly influence the ‘baseline’ of 250.000 [metric tons]. Furthermore, it should be noted that Scope II emissions are based on ‘location-based’ emissions, even in the case of the Leiden office where green power from Vattenfal is used.
The total sum of emissions from 2019 are then 202.795 [metric tons], which is (even when accounting for methane slip) lower than the total amount of emissions that will be offset, i.e. is 250.000 [metric tons]. The baseline is thus a conservative estimate to ensure all Heerema emissions are accounted for in the future.
