The sustainability reporting was carried out in accordance with the GRI standards – the "comprehensive" option. Furthermore, Migros applies the additional protocol for the food processing industry. The reporting option "comprehensive" ensures that all essential aspects of sustainability management are covered in the reporting. The company's internal structures and processes and implementation indicators (Disclosure on Management Approach, DMA) must be reported for each aspect. The relevant GRI topics are determined by means of a materiality analysis. For more information, see "About this report".
