We are very proud that we, in close collaboration with the ETC association, have become the first workshop in the Netherlands to achieve the GroenGedaan! certificate. GreenDone! is not a new ‘green hype.’ It is a sustainability standard that allows clients and contractors to showcase their commitment. It is supported by leasing companies, government, municipalities, provinces, fleet owners, insurers, ANWB, and consumers. In other words, our customers. A proper representation of these parties determines, through the College of Experts, the content of the Package of Requirements.


GroenGedaan Certificate

An increasing number of our customers are embracing GroenGedaan!. Therefore, you’ll come across it more and more often as a wish or requirement in tenders and procurement. Furthermore, the certification is included in government Green Deals, such as Zero Emission. The standard has been set! GroenGedaan! isn’t just some vague green concept; it’s actually a form of ‘good entrepreneurship.’ Sustainability involves being mindful of resources, conserving energy, ensuring the sustainable employability of personnel, preventing waste, and promoting reuse, among other things. GroenGedaan! provides us with guidelines on how best to implement these practices and what to focus on to achieve and maintain certification. It’s very practical and pragmatic, developed by clients/customers and outlined in the Requirements Package. So, GroenGedaan! not only contributes to a better environment and society but also helps control our costs and build customer loyalty.
