To push sustainable value creation forward, we have established a clear vision about how to integrate the Sustainable Development Goals into our daily operations. We want to continuously challenge ourselves to develop more sustainable solutions within our portfolio so that our operations become more environmentally friendly. We identified eight sustainability themes that will support us to create sustainable value.

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 organisations 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.
