Independent think tank for a healthy, sustainable, and fair food system
Through fact-based research, progressive debate and strategic collaboration, we leverage the power of food retailers, brands, and governments to drive change. Questionmark is funded by philanthropic donations.

Everything we do runs along three lines: Health, Environment and Human Rights. These are the focus areas through which we engage the supermarkets, brands and governments that determine what ends up on the shelves.
A food environment where the healthy choice is the easy choice. Obesity and diet-related disease are rising fast, and food environments shape that curve.
A retail sector that takes responsibility for its climate and biodiversity impact. Food systems drive over a third of global emissions.
Fair conditions for farmers and workers across the supply chain. Too many still earn too little to sustain their families or their land.
Our recent impact
In 2025, we worked with 35 retailers across 9 countries, sparking stronger climate targets, supporting a fair supply chain, encouraging healthy sales, and expanding government monitoring of supermarket sustainability. Take a look at our most recent impact below.

Our three pathways: how change happens
We envision a world with a liveable climate, thriving biodiversity, a fair society, and good health for all. Realizing this vision requires reversing persistent negative trends rooted in today's food system. Within this system, food retail chains are the most influential actors. With our work, we follow three pathways that lead to change:
Our benchmarks put retailers in a race to the top, using data and public visibility to drive better performance.
Using our insights, we bring retailers, suppliers and market authorities together in collaboration to take steps no single party can make alone.
We advocate for for legislation and government monitoring, so improvements become structural, not incidental.
Where we create impact
We focus on the retailers with the greatest market power, since a handful of chains determine what ends up on the shelf for millions of people. We work closely with local civil society partners in Belgium, France, Germany, the Netherlands, Poland, Spain, Switzerland, Sweden and the UK, comparing the retailers that hold the majority of market share in each.
