ABOUT US

City Science is an SME founded in 2015 with a core mission of delivering decarbonisation. We help organisations who are committed to decarbonisation achieve meaningful and quantifiable carbon reductions quickly and efficiently.

Our software and product development team produce innovative and uniquely insightful digital tools, like Cadence and our decarbonisation tool, to successfully deliver our projects.

We work collaboratively across our consultancy team made up of transport, energy, sustainability, carbon accounting and applied data science specialists to provide integrated solutions to our clients.
