Boskalis CSR report 2017

Impact on the environment CSR 2017 – BOSKALIS 42 such fuels is relatively easy to carry out. As they become available in large volumes at a lower price, biofuels will offer an economically viable, sustainable alternative to fossil fuels. The International Energy Agency predicts that in 2050 about 27% of the fuels for all transportation forms will come from biological sources. Boskalis is currently frontrunner in the area of sustainable marine biofuels, thanks to the pilots carried out in cross-sectoral collaboration with GoodFuels. The pilots, held between 2015 and 2017, using Marine Gas Oil (MGO) type biofuels that meet the most stringent sustainability standards, were positively assessed. In view of the positive results with marine biofuels, their use could reduce emissions in our fleet, to an extent that no other fuel can currently achieve without requiring costly fleet renewal or retrofitting. In addition, the possibility to use lower-cost blend biofuels, will enable us to create economically viable solutions. However, as long as regulations and legislation are lacking, the success of our sustainable solutions depends largely on the willingness of our clients to invest in low-emission alternatives. It is for this reason, that Boskalis has – where possible – made MGO biofuel the fuel of choice in its tenders in the Dutch market. In this way, we actively encourage clients to choose for this sustainable, be it more expensive, option. Where possible also, we make our fleet more sustainable by means of energy-saving measures: by making the installations we use on board our vessels, such as cooling, ventilation, AMBITIOUS CO 2 REDUCTION PLAN In 2017, we once again received the highest-level certification on the CO 2 Performance Ladder for all Boskalis business units in the Netherlands. The CO 2 Performance Ladder is a tool used by Dutch government agencies and businesses to recognize performance in the areas of energy saving, efficient use of materials and renewable energy. Performance Ladder certification is asked in many tender evaluation procedures. In its activities on the Dutch market, Boskalis has the ambition to reduce its CO 2 footprint for its own equipment by 35% on local projects by 2022, compared to 2017. This will be achieved through improving energy efficiency based on technical developments, raising employee awareness and the use of biofuels in our equipment. The use of biofuel has been made possible, based on the successes of pilot projects. Boskalis used a drop-in marine bio/fossil blend fuel for its cutter suction dredger Edax during operations at the Marker Wadden project in 2016. The biofuel used was a biofuel/fossil fuel blend of up to 50%. The biofuel was made out of lignocellulosic waste streams from a Finnish pulp and paper company. CO 2 reductions were in line with expectations. Another successful pilot was the use of bio/ fossil blend fuel in trailing suction hopper dredger Willem van Oranje in 2015.

air-conditioning and lighting more efficient. In addition, our Ship Energy Efficiency Management Plan on board our vessels, serves to promote awareness of efficient energy consumption amongst our crews. ENERGY-EFFICIENT OFFICES We aim to further reduce our CO 2 footprint through energy- efficient offices and warehouses. We also want to ensure healthy workspaces for our employees. To achieve these goals, we continue to take measures to structure and optimize the energy management systems of our Dutch offices and warehouses. In line with the targets of EU Energy Efficiency Directive, Boskalis aims to have energy-neutral offices and warehouses in Europe by 2050. In order to achieve this target, a minimal 2% energy reduction per year must be achieved for all our offices and warehouses in the Netherlands. The Energy Management System (EMS) was implemented in 2016 for our Dutch offices and warehouses and continues to keep us focused on energy consumption and cutting back CO 2 emissions. The implementation of the EMS is a significant step towards the goal of energy-neutral offices. Since 2016, we use electricity generated from Dutch wind energy – with zero CO 2 emissions – for all our offices in the Netherlands. The CO 2 Performance Ladder (level 5) and the BREEAM Early 2018, Boskalis signed a five-year contract of intent with GoodFuels for the purchase of drop-in quality biofuel. The first commercial delivery by GoodFuels in 2018 was a 30% biofuel/ fossil fuel blend made out of used cooking oil. This blend was used by our trailing suction hopper dredger Causeway, during operations at the Hartel Tank Terminal project in the Port of Rotterdam. Based on our extensive knowledge acquired from the pilots, we expect that significant cuts in CO 2 emissions will also stimulate adoption of biofuel on other Boskalis projects in Northwestern Europe. In this way, biofuel prices are likely to drop as a result of scalability. In turn, this will stimulate even more widespread use of this environmentally friendly fuel. To achieve the ambitious CO 2 reduction, commitment from clients is essential. reduction can be achieved through improving the efficiency of our processes and increasing energy consumption awareness amongst employees and stakeholders. Launched in 2016, the ‘Keep Fuel in Mind’ initiative aims at bringing about a change in behavior amongst our operators. This is done by recording and monitoring equipment fuel consumption levels and discussing ways of saving fuel while on the job. Further CO 2
