Boskalis Sustainability Report 2020

PROTECTING THE OCEANS Salvage has had one of the busiest and most successful years in its rich history. The most impactful project took place off the coast of Sri Lanka. A VLCC tanker carrying two million barrels of crude oil caught ablaze following an explosion and fire in the engine room. The fire was controlled and a potentially huge environmental disaster was averted. The crude tanker was towed to the United Arab Emirates, where the crude oil cargo was safely transferred to other vessels. ADVANCING THE ENERGY TRANSITION Our energy transition-related projects continued in 2020, including acquiring a spectacular contract for the world’s largest floating wind farm: Kincardine, as well as the contract for the Fécamp wind farm offshore Normandy, France that is expected to provide enough electricity to meet the power needs of 770,000 people. The combination of the heavy transport fleet, our seabed and subsea capabilities, large anchor handling vessels together with our project management and engineering skills, uniquely positions Boskalis for this rapidly growing market. SUSTAINABLE GROWTH In 2020, I’m proud to share that we ended the year with a revenue of EUR 2.5 billion, EBITDA of EUR 404 million and a historically high order book of EUR 5.3 billion. At the same time, we were able to substantially improve our strong financial position boasting a net cash position of EUR 439 million as per year end. While the COVID-19 pandemic stretched our focus, the urgency of delivering our economic value in a sustainable manner has never been higher. We continue our efforts to deliver on our sustainability ambitions, to enhance the positive impacts of our operations and minimize the negative. This is reflected in the update of our sustainability strategy in 2019 and policy commitments in 2020. ROAD TO ZERO In 2020, we made it our ambition to be net climate neutral across our operations by 2050. Delivering on this will be one of our biggest challenges in the years to come, but also an area for significant opportunities. We are actively exploring cleaner fuels, efficiency improvements and carbon offset as approaches to mitigate our emissions. We are also focusing on our low-carbon commercial offering for our clients, incorporating design and operation emissions reductions into our tenders. Our business in the Netherlands is at the forefront of this effort, with 80% of our tenders incorporating a sustainability component. In 2020 we installed more than 5,000 solar panels on the roof of our distribution center in the Netherlands, producing 1.6 million kWh of green electricity per year, or 15% of our domestic needs. BIODIVERSITY FRAMEWORK At Boskalis we value the natural environment. In 2020 we had the honor of establishing collaborations with two international NGOs to help advance our approach on this topic. We entered into a

collaboration with Wetlands International, an NGO dedicated to protecting and restoring wetlands around the world. Together we are exploring the potential of wetland habitat creation for carbon sequestration. Another important project we initiated this year was with the International Union for Conservation of Nature. Through this collaboration we are working to develop best practices in biodiversity performance planning and monitoring. Based on this work we have identified biodiversity priorities and clarified our ambition and objectives as set out in our biodiversity framework. This is an increasingly important area for society and therefore for us and our clients. Looking forward we will continue this important work to improve the way we measure our impact on biodiversity impacts and the effectiveness of our nature-based solutions. SOCIAL IMPACT Despite the COVID-19-imposed restrictions limiting the ability to interact with communities, we still managed to deliver a number of community contributions in particular in the areas of safety training and youth education. We also took this time to focus on social impact management process and internal capability, updating our policy, developing training and incorporating new tools into our Way of Working quality management system. This effort places us in an ever stronger position to deliver complex projects in a socially responsible manner. CARE FOR OUR PEOPLE This year we marked the 10th anniversary of NINA, our successful, behavior-based safety program. Our planned celebrations were unfortunately disrupted by the restrictions imposed by the pandemic, but this should in no way detract from the pride we can all share in seeing our Lost Time Injury Frequency fall by no less than 95% in the last 10 years. After a true roller coaster ride over the last 12 months, I am looking forward with confidence. We may not be there yet, but thankfully, it appears as if the end of the pandemic is in sight and as a company we are in great shape. Not only do we have a record high in our order book, a strong financial position, and the best team of professionals in the industry, but we are on course to deliver ever more sustainable solutions to the challenges the world faces today. On behalf of the Board of Management, I would like to thank all of our colleagues for their commitment and dedication over the past year; I have great admiration and respect for the dedication shown during this challenging year. Furthermore, I would like to thank our clients, partners and shareholders for the trust and confidence they place in us.
