The assistance is focused on cities, businesses and nations. Circle Economy has nine focus areas:

1. circular jobs initiative
2. finance
3. metrics
4. data
5. digital
6. textiles
7. built environment
8. capital equipment
9. design for circularity

The assistance for cities is delivered mainly through the Circle City Scan, which aims to guide cities on their journey to make their linear economies circular, by using data to inform multi-stakeholder decision making and accelerate the transition to CE. Also, it elaborates on Circularity Gap Reports for countries, which provide insight into the best interventions that can boost circularity at a national level and the tools that can be used to monitor the progress.

In addition, businesses are assisted through the Circle City Scan Tool approach that helps align sustainability targets with commercial targets by pinpointing the opportunities for improving product design, service design and business model innovation.

Circle Economy has supported over 30 cities around the world in creating CE strategies.

Circle Economy currently has worked with more than 20 countries, a large number of which are part of the European Union. 

1. Metrics and indicators; data and knowledge creation; digital tools; jobs; built environment.
2. Business strategies; finance; agrifood.
