The Postcode Lottery organises the Green Challenge competition to stimulate the development of commercial projects and products that contribute to the reduction of carbon emissions or otherwise help to preserve the environment and combat climate change. Five years ago, Marieke was closely involved in setting up the first Green Challenge together with PICNIC.

"The Postcode Lottery wants to make a difference, and that's why we support creative entrepreneurship. It is important that people know that the climate is changing, but even more important that something is being done."
