Sustainability programme

We believe in making organisations more sustainably from the inside out. That is why we challenge employees to reduce their footprint and increase their handprint in 40 days. 

Our positive approach, the competition element and the concrete actions, will help employees to create new habits, develop a sustainable mindset and make a measurable impact together. With our bottom-up approach, we engage employees with sustainability and the sustainability ambitions of your organisation and empower them to take action.

Why 40 days?

A Footprint Challenge lasts 40 days to bring about sustainable change. New habits cannot be “installed” in our brain overnight.

Experience shows that 40 days are needed to learn and anchor new preferred patterns in your brain. To sustain that, people need appreciation, encouragement and success experiences, and we ensure that during the Challenge.

Benefits for your organisation

  • More engagement with sustainability at home and at work
  • Increase support for and visibility of your sustainability goals
  • Build a stronger team and create company pride, making an impact together creates a bond

A Footprint Challenge can take place on an individual level, in teams (for example between different departments) and between different organisations.
