"MariekeMarieke van Schaik (1970) is managing director of the Dutch Postcode Lottery, which is the largest charity lottery and private fundraiser in the Netherlands.  In 2013, the Dutch Postcode Lottery divided 302 million euros among its beneficiaries in the fields of poverty alleviation, human rights, nature and environment. The lottery was founded in 1989 and supports organisations that seek to create a fairer, greener world. Half the proceeds raised by the Dutch Postcode Lottery are donated to charity. Since it was founded, the lottery has donated more than €4 billion to charity.

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. Eight 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."
