Driving the transition to a new economy
We help businesses, cities, and nations thrive in the circular economy so they can stay competitive, build resilience, and create lasting value.
What we do
At Circle Economy, we provide data-driven assessments to track progress towards a circular economy. We turn these insights into action by developing tailored strategies and supporting implementation through consulting and advisory services. To scale our impact, we build capacity across sectors with tailored training programmes and digital learning tools.
Who we are
Circle Economy is a global impact organisation, founded in 2011 by Robert-Jan van Ogtrop in Amsterdam. Today, we are an international team of 60+ experts helping businesses, cities, and nations seize new opportunities, reduce costs, create jobs, and drive behavioural change.
Our flagship Circularity Gap Report (CGR®) sets the global benchmark for measuring circular progress. We also manage the world’s largest circularity database, encompassing over 90 nations, 350 cities, and 1,000 businesses. This evidence base powers practical tools and strategies that guide the transition towards a more regenerative, resilient economy.
‘It is time to use our collective intelligence to redesign our way of working before we reach a point of no return. At Circle Economy, we look to nature for inspiration since it is, in itself, a perfect circle’.
