Holcim is a Zurich-based sustainable building materials company, which makes concrete, cement, aggregates, roofing and related products. The Circular Cities Barometer is a data-driven project.

Holcim, which is a thought leader around sustainable construction topics, wanted to reach Bloomberg’s audience of business influencers, including developers, architects corporate clients, city planners and organizations active in pursuing sustainable living.

Holcim, which has been in the forefront of thinking regarding the concept of circular cities, recognizes that the pursuit of net zero carbon emissions must begin with the world’s urban areas, where more than 60 percent of global greenhouse gasses are produced, according to the United Nations. Holcim and Bloomberg Media partnered to create the Circular Cities Barometer, to understand how, and which, cities are leading the way toward circular and sustainable living.

Holcim-Bloomberg’s goal in launching the Circular Cities Barometer was to assess how fast 25 global cities are transitioning from a linear economy - taking, making and wasting - to a circular economy of reducing, reusing and recycling.

To target business decision makers, we focused the project on the Barometer, which ranks 25 global cities based on how fast they are transitioning to circular economies. The Barometer was powered by more than 300 data points and a proprietary Bloomberg algorithm. The data was gathered from public sources, weighted and the Barometer calculated over the course of four months, with detailed narratives explaining why each city scored as it did created over a further two months.

Data was central to the project; without it, the project would not exist.
