CSR Report 2018

MANAGING OUR IMPACT ON THE ENVIRONMENT CSR 2018 – BOSKALIS 20 REDUCING EMISSIONS OUR IMPACT AND MANAGEMENT APPROACH Climate change and its consequences are increasingly urgent topics for society and our sector to address. At Boskalis, we contribute to greenhouse gas emissions mainly through our fleet operations, which account for around 99% of our Scope 1 and 2 CO 2 footprint. In 2018 this totaled 1.18 million MT. Whilst this is a small fraction of the total annual global shipping emissions of approximately 1,000 million MT, we want to take responsibility for our share. This year we established our CO 2 emissions reduction program as a step to ensure our fleet and operations are compliant with the IMO emission reduction target for maritime transport (50% by 2050 relative to 2008). The program will also follow innovations that offer commercial solutions for our clients that go beyond compliance, for example through the use of biofuel. MEASURING OUR CO 2 FOOTPRINT Measurement of our CO 2 footprint is central to our ability to manage and ultimately reduce it. In the past years, we have looked to improve data quality through the introduction of a specific CSR data reporting system and associated reporting processes. This year we have further focused on understanding and analyzing our CO 2 performance, so we can target areas for improvement. Our focus in the coming period will be to develop a method by which we can accurately calculate and report CO 2 efficiency across our diverse business.

FOCUS ON EFFICIENCY In addition to measurement, we take action by implementing fleet efficiency improvements. This has the dual benefit of reducing fuel cost as well as carbon emissions. We do this through several initiatives, including: ‚ ‚ Sustainable and energy-efficient design of our new-build ships and optimization of ships’ trim. ‚ ‚ Applying technical, operational and data-driven innovations, such as hull cleaning, better voyage planning, exhaust gas treatment technology and optimization of operations. ‚ ‚ Changing behavior and promoting awareness amongst staff and crews, for instance by way of awareness programs and our Ship Energy Efficiency Management Plan. EMISSIONS IN 2018 In 2018 total Scope 1 and 2 CO 2 emissions of the group amounted to 1.18 million MT (2017: 1.22 million MT). We measure and report on the fleet’s total CO 2 emissions based on fuel consumption. In 2018 we recorded a slightly lower total Scope 1 (1.18 million MT) CO 2 emissions compared to 2017 (1.22 million MT). The emissions from our offices remains the same. The decrease in Scope 1 emissions is mainly due to changes in our Dredging and Infra operations, which is reflected in a CO 2 emission decrease of approximately 11%. The fuel consumption and therefore CO 2 emissions from our fleet, in particular the dredging fleet, are influenced by several variables
