Sustainability

Our ambition & strategy

At DEME, it is our ambition to meaningfully contribute to sustainable solutions for the global environmental, societal, and economic challenges facing our world today. In addressing these major challenges, we continue to strive toward improving the sustainability of our own operations. This has led to us developing a two-dimensional strategy for sustainable performance in which we aim to “Explore” and to “Excel.” We believe this strategy will help us create sustainable value for our customers, DEME, and society as a whole.

  • Explore sustainable business solutions
    By continuously challenging ourselves to enlarge our sustainable business portfolio.
  • Excel in our operations
    By maintaining and further strengthening our sustainable performance in our daily operations.

Our strategy makes a clear distinction between material topics and relevant topics:

  • Material topics: These are our top priorities that have the greatest impact on our performance and sustainability goals.
  • Relevant topics: These are important for continuous improvement, although they have a lower strategic impact.

The split between material topics and relevant topics is guided by the double materiality assessment, which looks at how our activities impact the world and how environmental and societal changes affect our business. This two-way view helps us identify the most important topics and align them with our strategic goals.

ESG Ratings & Indexes

DEME’s sustainability performance has been assessed by multiple ESG analysts and agencies. The ESG ratings indicate the sustainability performance of a company based on publicly available information. 

Sustainability governance

Our sustainability governance model focuses on two core elements:

1. TO EXPLORE SUSTAINABLE BUSINESS SOLUTIONS (CONTINUOUSLY CHALLENGE OURSELVES TO DEVELOP MORE SUSTAINABLE SOLUTIONS)

2. TO EXCEL IN OUR OPERATIONS (SUSTAINABLE PERFORMANCE IN OUR DAILY OPERATIONS)

There are five main layers within our governance structure: the Board of Directors, the Executive Committee, Sustainability Board, Sustainability Team and Process Owners of the different Segments and supporting services.

Board of Directors

Specific sustainability topics related to safety and greenhouse gas emissions reduction are on the agenda at every meeting of the Board of Directors. The general progress of the implementation of the sustainability strategy is discussed once a year.

Executive Committee

Every year, the Executive Committee reviews and approves our sustainability programmes, along with the related objectives and targets.

Sustainability Board

The Sustainability Board ensures regular and consistent updates to the Executive Committee, CEO (both represented in the Sustainability Board) and Board of Directors. It provides guidance on both strategic and operational sustainability matters to ensure that decisions align with our values, sustainability strategy, and objectives. In 2024, the Sustainability Board met 7 times to evaluate the sustainability performance of our project portfolio, and the progress made towards our objectives from both a strategic and operational perspective.

Process Owners

Sustainability Ambassadors within the segments, Theme Leads within the supporting services and Tender Sustainability Single Point of Contacts (SPOCs) have been appointed to support the further implementation of the operational sustainability objectives, targets and measures across the organisation.

Ethics and Business Integrity

DEME Code of Ethics and Business Integrity
The DEME Code of Ethics and Business Integrity is based on the principle that we should always act with honesty and integrity in all matters. The Code’s purpose is to help our employees engage in the right behaviour and align with our core values. Complying with our Code of Ethics and Business Integrity paves the way for stronger relationships by enhancing the trust between us and our stakeholders. Our Code and its related documents provide useful guidance in making sound ethical business decisions in our daily work and inspire dialogue about the key ethics and compliance issues that we may face. We also developed a DEME Code of Ethics and Business Integrity for Business Partners, based on the same principles.

Raising and reporting integrity issues
At DEME we believe that the final building block of our integrity programme is the possibility for both our personnel as well as any concerned third party to raise integrity concerns without fear of reprisal. For guidance on this topic we refer to our “Whistleblowing Policy Summary”.

Social dialogue
We are convinced that social dialogue and open communication between employees and management are essential for creating optimal and safe working conditions, establishing a fair policy in terms of working conditions and successfully executing all our activities.

CO₂ performance ladder

In the Benelux, DEME is certified according to the requirements of the CO₂ performance ladder, which encourages companies to map out and reduce their CO₂ emissions. Since 2012 LRQA (an accredited independent party) has regularly verified our processes and results. In 2018 DEME passed the renewal audit with the highest qualification level (level 5). Widely used, the CO₂ performance ladder is an instrument that helps organizations reduce their carbon emissions, in the performance of projects and in their business operations. The principle behind the ladder is that efforts concerning CO₂ are rewarded economically; i.e. the higher score on the ladder, the better the company’s assessment in tenders.
