For each use of crop protection products and fertilisers, companies record their usage data in the MPS record-keeping system. In addition, they record their usage in the areas of energy, water and waste, and indicate where, when and how much starting material was purchased. Points can be awarded for each aspect. Based on the total number of points awarded, a company receives an MPS qualification of A+, A, B or C, where A+ is the highest attainable qualification.
A total of 110 points can be awarded. After recording data for thirteen consecutive periods (four quarters), the registration is checked in a company audit, and an independent certification body issues the certificate. This is followed by the first MPS-ABC qualification, which is recalculated once per quarter.
