The Dutch Public Procurement Expertise Centre (PIANOo) acts as a help desk for Sustainable Public Procurement matters, and as a help desk for substantive questions about SPP criteria. Should you wish to make contact, you can use the Dutch Public Procurement Expertise Centre's general contact details or click on the ""Provide feedback"" button on this website's home page.
Each criterion is accompanied by a ""Provide feedback"" button during the annual updating period. Any feedback goes directly to the parties that carry out the updates for both ministries and the Directorate-General for Public Works and Water Management and will be processed by them.
The Directorate-General for Public Works and Water Management is responsible for updating the SPP criteria and this website.
This website and the SPP criteria are managed under the responsibility of two ministries:
- the Ministry of the Interior and Kingdom Relations;
- the Ministry of Infrastructure and Water Management.
