About

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

Our strategy focuses on leveraging the influence of European food retailers, brands, and governments 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 way of working

We develop and disseminate solutions for a future proof food system and build movements to accelerate and implement change

We help decision makers in and around the food sector understand the urgent challenges the food system faces and develop and disseminate new solutions. 

We follow the ‘system approach’, which means we consider all the elements in the food system and how they influence each other. 

We carry out our strategy by

  • conducting (mostly unsolicited) research & advisory
  • organising collaboration among various stakeholders
  • stimulating and organising public debate

In all of our work we engage civil society organisations, our Scientific Council, companies and governments.

Levers for change

Our programmes focus on leveraging the power of retail, A-brands, advertising and governments. They have great potential to stimulate healthy, sustainable, just and animal friendly production and consumption of food.

Retail

In Europe, 70% of the food we buy comes from supermarkets. At the same time only a handful of supermarkets per country are situated between food producers and consumers. This makes supermarkets a powerful lever to transform eating patterns and food production methods. 

Advertising

Advertising encourages people to consume unhealthy and unsustainable food. But responsible advertising can positively influence consumption norms and contribute to healthy and sustainable consumption.

  • Value-driven  
  • Pioneering

Governance and financials

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.

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