Sustainability report 2019

31

The decrease in Scope 1 emissions is mainly due to our drop in fuel consumption in our dredging fleet. This is reflected in a CO 2 emission decrease of 6%. Carbon emissions from our dredging fleet decreased 10% in 2019. This is partly driven by an overall decrease in fleet utilization and in particular a 11% reduction in utilization of hopper dredgers. This made a significant contribution because they represent 85% of the total fleet fuel consumption for dredgers. The recycling of hopper dredger Shahaf and cutter dredger, Capricorn in January 2019 also had an impact, as these represented 5% and 1% respectively of total consumption in 2018. For Offshore Energy, CO 2 emissions (0.67 million MT) have decreased slightly in comparison to 2018 (0.69 million MT) mainly related to the phasing our of a T-class vessel over 2018

and 2019, combined with growth in occupation for the Atlantis and Davinci. Overall further asset occupation in 2019 was more or less comparable to 2018. We do not report the emissions from Towage as this business has been incorporated in joint ventures since 2016. The emissions from our Salvage operations are not reported in our Scope 1 and 2 CO 2 emissions, we rely on vessels from the other divisions or third party assets for these services.
