The workshop focusses on the experience Rijkswaterstaat gained with Circular Procurement (CP). We would like to inspire other procuring parties and market participants to stimulate the demand for circularly procurement. CP and Green Deals are relevant to green cities as they are at the forefront of CO2 mitigation and sustainable development. Every project executed within a green city benefits when it is procured in a circular way. This contributes to climate mitigation and to greener cities.
