  • What is Questionmark? 

    Questionmark is an independent organization that aims to create a race to the top, by developing and publishing benchmarks on the sustainability of products and retailers, concerning the environment, human rights, animal welfare and personal health. Questionmark considers a public debate, fed by relevant factual information, vital for the race to the top amongst companies. Therefore it makes product information accessible and transparent via a consumer website and app.

    Questionmark collects information about products and production methods in a database. There are currently more than 80,000 products in the Questionmark database. The Questionmark website and mobile app make the information in the database easily accessible and searchable.

  • How does the website work 

    You can easily look up products on the Questionmark website. At a glance you can see all information available of a product.

  • What is Transparent on Sustainability? 

    Questionmark is collaborating with the Ministry of Agriculture, Nature and Food Quality, Wageningen University, The Sustainability Consortium (TSC) and companies on an improved method for displaying the sustainability of food products. TSC has determined the most issues for each production chain and asks companies to indicate which measures they take to tackle these issues. This method is still under development. In the meantime Questionmark indicates whether a product bears top certificates or (other logos or quality marks) and on which these top certificates focus. Read more about the developments here.

  • How does the scan app work? 

    If you want to know the score of a product quickly, you can look it up in the app with the search function or you can choose a category. Those who are in the store or in front of the refrigerator can use the app to scan the barcode and read whether a product has (top) quality marks and whether a product is healthy.
