Emissions summary

Total emissions

Our total emissions were up 16% due to the inclusion – for the first time – of Well-to-tank (WTT) emissions^. (Because we have not previously reported on WTT emissions, the figure is differentiated by the lighter shade of maroon.) Excluding WWT emissions, our total emissions would be down by 9% on last year, due to reduced dredging activity and fewer shipping movements.

^ WTT emissions occur during fuel production, processing and transportation until fuels are ready for use. They also cover the entire upstream process.

^^ CO2e stands for “carbon dioxide equivalent”. It is a single unit that accounts for all greenhouse gases, including carbon dioxide, methane and nitrous oxide.
