Our mission

Questionmark is a think tank committed to creating a healthier, more sustainable, and fair food system. 

Our strategy focuses on leveraging the influence of food retailers, brands, and governments across Europe to drive meaningful change. 

We achieve this by stimulating competition and/or collaboration among companies and inspiring governments to regulate where the market needs level playing field.

Our Governance

Our core activity consists of independent projects. These are funded by donations from philanthropic funds and civil society partners. Names of funders can be found with the description of each individual project.

On occasion, when it truly aligns with our mission, we deliver data and research services on commission.

Accountability for our governance and finances can be found in our annual reports

We have an integrity policy in order to avoid conflicts of interest and adverse incentives.
