MANAGING OUR IMPACT ON THE ENVIRONMENT SUSTAINABILITY REPORT 2019 – BOSKALIS overall footprint. Biofuels offer an economically viable and sustainable alternative to fossil fuels. We recognize that biofuel can result in significant CO 2 reductions and are a key part of reducing emissions in the short to medium term, but we believe that over the long term, biofuels will not be sufficiently available nor clean enough to reach our 2050 emission target and therefore form only a part of the solution. BOSKALIS ON BIO The Boskalis on Bio program is part of our decade-long exploration of alternative fuels. Its aim is to realize a substantial and sustainable reduction in carbon emissions from both our vessels and dry earthmoving equipment and trucks. For Boskalis, it was important to find a truly sustainable biofuel that we could scale across our fleet. In 2018 we reported our commitment to support the IMO emission reduction target for maritime transport (50% by 2050 relative to 2008). In 2019 several initiatives to reduce emissions got underway, most critical of which was to explore the pathway for Boskalis to contribute to the ambitions of the Paris Climate Agreement. The outcome of the work was the establishment of our new CO 2 reduction target, where we aim to be climate neutral by 2050 across our global operations (Scope 1 and 2). With this ambition we aim to maintain our position as an industry leader in emissions reduction and drive competitive advantage through our ability to offer low carbon solutions for our clients. With this in mind we have also set ourselves the challenge to further support our clients to select low carbon alternatives by not only developing solutions, but also making these options more visible and accessible in our commercial offerings. We see collaboration with our clients and the sector as a whole as essential to finding the solutions to reduce emissions of the works we do. Over the coming years we will need to focus on research and development for the low carbon fuels and technologies that will power our fleet of vessels and our land based equipment in the future. Our average ship has a lifespan of 25-30 years, and whilst there is no silver bullet to reduce the emissions, we envisage hydrogen as a strong contender for the future. Transition fuels will remain important however, and we will continue to explore and invest in these solutions such as methanol, ethanol and ammonia as alternative fuels. We will also continue our Boskalis on Bio Program, outlined below. BIOFUELS Innovations that enable us to cut carbon emissions from our large global fleet can make a significant contribution to reducing our
This led to a strategic partnership with GoodFuels Marine and engine manufacturer Wärtsilä to couple technical innovations with developments in biofuels. The results have led to a fuel that can offer a 90% reduction in emissions compared to fossil fuels. This is a major contribution to the creation of the first global market for advanced biofuels for the marine industry. Our deployment of biofuels continues to grow. We are using ‘drop in’ blends of light biofuel and marine gas oil in our work around the Netherlands. We also use it on some of our projects on the North Sea, all being bunkered from ports in the Netherlands and we will be expanding this further over the coming years. On the Marker Wadden project in the Netherlands, our cutter suction dredger Edax dredged for six months using a 50% biofuel blend consisting of residual products from the paper industry. This resulted in a significant reduction in carbon emissions. The growth in viability of biofuels is slowly contributing to a trend among clients in the Netherlands, who are starting to include a biofuel requirement in their tenders. Boskalis is installing the export cable for the Borssele offshore wind farm on behalf of TenneT. During this project, several Boskalis vessels – including the jumbo trailing suction hopper dredger Prins der Nederlanden and our cable-laying vessel Ndurance – operated with a blend consisting of up to 30% biofuels. TenneT welcomed this step by Boskalis, and we expect other clients to take this approach as they look to reduce their environmental footprint. WILLEM VAN ORANJE ON 100% BIOFUEL OIL In 2019, we achieved a major milestone with the deployment of our hopper dredger, Willem van Oranje, using 100% biofuel oil. This is the first dredging vessel in the world to operate on 100% biofuel oil, a fuel made entirely from used cooking oil. This represents a 90% reduction in the vessel’s carbon emissions. This step forward is the culmination of two years of testing in collaboration with our strategic partners, GoodFuels Marine and engine manufacturer Wärtsilä. OTHER ALTERNATIVE FUELS Boskalis is also exploring other alternative fuels. Our joint venture Keppel Smit Towage launched its first LNG (liquefied natural gas) dual-fuel harbor tug in the port of Singapore. KST Liberty was the first LNG-fuelled tug to operate in Southeast Asia. LNG reduces nitrogen oxides and sulfur oxides emissions, as well as reducing carbon emissions by 10%-15%.
To explore the potential to reduce fuel consumption as well as emissions to air, Boskalis tested the use of a fuel water emulsion in
