Minimum sustainability standards

The council encourages its suppliers to conduct their operations in a sustainable manner, in line with our own priorities and commitments.  These can be found in our Sustainable Procurement Policy (160.1KB) and our Environmental Policy (currently being updated).

In order to ensure that our suppliers share our commitment to reducing the impact of the products and services they provide, we have included questions on sustainability in our tender selection process.

Here is some guidance on sustainability issues suppliers will need to address in our Pre Qualification Questionnaire (PQQ):


If you are invited to tender we may also ask you specific questions related to the specific project. All questions will be relevant and proportional to the contract and your answer should tell us how you propose to meet our sustainability aims.

You can see out standard Pre Qualification Questionnaire (PQQ) and Invitation to Tender (ITT) documents on the Tender documents and process page.
