Sustainability Day – 10 October 2026

Sustainability Day in the Netherlands is celebrated every year on 10 October. On this day, a wide range of activities focusing on sustainability are organised in various companies, organisations and schools, ranging from clothes swaps to litter-picking campaigns and workshops on recycling. Sustainability plays an increasingly important role in our society every year, and it is certainly worth giving it some extra attention. Sustainability Day centres on sustainable initiatives. Every organisation marks this day in its own way. Some businesses organise a clean-up campaign, whilst others opt for an exhibition showcasing a wide range of innovative and sustainable products. In recent years, sustainability has become the new normal. You’ve no doubt noticed that everyone is focusing on sustainability. Every new innovation must have a positive impact on society. People are living increasingly sustainably, companies are constantly highlighting their green credentials, and even in schools, this theme is impossible to ignore. In fact, every day is Sustainability Day.
