The City of Zurich
Zürich
For over 20 years, the City of Zurich has demonstrated the impact of continuous optimization in urban cleanliness management. By reducing resources by 10% each year, Zurich has achieved the same cleanliness levels with three times fewer resources, thanks to the compounding effect over time. While our original application for the Clean City label included a projection based on compounded annual savings, the current analysis focuses on real-world data from our 2025 client base, with non-compounded annual calculations.
Using the same methodological framework, we estimate the following environmental benefits for the year 2025 alone: •Direct CO₂ emissions reduction: 2,700 tonnes •Grey energy CO₂ savings from reduced fleet requirements: 2,800 tonnes. These figures reflect measurable impact achieved through optimized use of cleaning resources—namely, fewer vehicles, improved planning, and smarter deployment of operations.
Cortexia’s solution for improving urban cleanliness while controlling costs is very promising. The City of Zurich is proud to have made a major contribution as a partner in this development. We are confident that this solution has the potential to be a useful and indispensable tool for cities around the world.
Michael Ultsch, Division Manager at Zurich Stadt
The solution supports cities in managing their sanitation department, by providing an accurate and real time monitoring of urban cleanliness. A clean city is more attractive and healthy. Less litter will end-up in the environment. Cleaning resources are engaged when and where necessary, based on the cleanliness level to be achieved, savings in energy, water and costs will be accrued.
