Effect reporting

Effect reporting is important to show your internal organisation that circular procurement is a sensible thing to do. You report on the effects based on your definition of the circular economy and your ambitions in this regard. If they see the effects, people become aware of the impact of their efforts, which will motivate them even more to apply circular principles. Mapping the effects can also provide new insights, for instance which product groups have a high sustainability impact.

Once a circular procurement project is completed you should try to make clear what the impact is. For example, requesting a material passport detailing the composition of a product could be helpful in this respect. You can also determine the environmental footprint, for instance by means of an LCA, to provide insight in the environmental impact of a procured product.

Insights from procurement projects help to make the progress transparent at the organisational level. How many procurement projects did you make circular? What is the current level of reuse of the initiatives (e.g. repair, repurposing, recycling)? How many products have been saved, or how much raw material? And what has been the environmental impact?

Input- and impact monitoring

To measure performance, you can monitor either the input or the impact. Monitoring input is about the efforts that have been made. You can check, for instance, whether circular ambitions have been included in the tender or if award criteria regarding circularity have been used. Monitoring impact is about output, such as the amount of material used, or the amount of CO2 emitted.

Input versus impact monitoring: input monitoring looks at the efforts made at the start of the procurement process, while impact monitoring looks at the results once the procurement process is completed. (source: RIVM, 2018)

This means that input monitoring can take place once the procurement process has been completed, while impact monitoring can only take place after delivery of the product or service. In line with national objectives you should try to implement impact monitoring where possible. In case this is not possible, input monitoring is a good alternative.

Impact monitoring at product group level

You can only monitor the impact when the physical environment is impacted. In some product groups this occurs when you procure a product, e.g. buying a conference table made from local waste wood. In other product groups impact mainly occurs in the course of the contract, e.g. procuring a catering contract that includes a growth path towards a lower environmental impact of the food. For this type of product group impact monitoring can help to ensure a lower footprint over the contract period.

This means that impact monitoring requires a longer horizon beyond the procurement process, and the achieved impact can very well be the result of the procurement process that has been followed.

Apply MVI-ZET at organisational level

One of the ways in which public organisations can measure their progress is by using the Self Evaluation Tool for Socially Responsible Procurement (MVI-ZET, Dutch). The MVI-ZET allows you to indicate the themes and ambitions per procurement project. Besides ‘circular’ you can also think of ‘social’ or ‘biobased’. MVI-ZET has been linked to TenderNed and has access to all your tenders. This enables reporting at the organisational level. MVI-ZET is currently being further developed to include impact monitoring.


  • Decide for each procurement project how you want to monitor the effects and make agreements with your suppliers about the data you need from them.
  • Provide regular process reports at the organisational level. This creates support for future procurement projects.
  • Focus on communication of visible successes in the physical environment to inspire others to seize the opportunities offered by circular procurement.
