Circular cities barometer

Cities leading the circular economy

Cities are at the forefront of the shift to a circular economy. With an estimated two billion new urban residents by 2050, our cities need to become more circular to secure a sustainable future.

We created the Circular Cities Barometer with Bloomberg Media Studios to identify the world’s top cities at the forefront of circular living. This digital dashboard shows how the top 25 cities are transitioning from a linear “take, make, waste” economy to a circular “reduce, reuse, recycle” model.

What makes a city circular?

Holcim and Bloomberg created the Circular Cities Barometer to measure how fast 25 cities around the world are leading the shift to the circular economy. We rated cities based on a dozen circularity indicators. The results provide valuable insights into measures cities can take to be more circular.

How do we build green cities?


We reduce the footprint of construction with our sustainable building solutions.

Our ECOPact green concrete range delivers 100% performance with up to a 90% reduction in carbon emissions compared to standard concrete. Our 3D printing ink, TectorPrint, enables smart design with minimal material use for maximum strength.


With 80% of buildings and infrastructure projected to still be in use by 2050, green retrofitting will be key. Elevate's green, cool and solar-enabling roofs make buildings more energy-efficient and reduce the urban heat island effect. Renovating with our Airium insulating system increases energy efficiency, equipping buildings for years of use and reuse.


As a world leader in recycling, our goal is to double our current recycling efforts and recycle 100 million metric tons by 2030.

Part of our Solutions & Products offer, Malarkey Roofing Products is a pioneer in circularity with GreenCircle-certified shingles, incorporating recycled plastic bags and tires.
