Wouldn’t it be great if there were a scientific tool that could help you test a new policy measure?
The European City Calculator is a free, online simulation tool that helps cities explore the impact of different decarbonisation strategies on their local emissions. Designed to support local authorities in building credible and data-informed climate transition plans, the EU City Calculator allows users to simulate various climate policies and adjust ambition levels. Cities can visualise how those choices affect emissions over time, making the tool a practical and evidence-based companion for planners working toward climate neutrality.
Developed by Climact, with the support of Energy Cities, Carbon Market Watch, and the Potsdam Institute for Climate Impact Research (PIK), the webtool was originally financed through the Horizon 2020 EUCityCalc project and is now under further development through SPARKLE.
Why the European City Calculator is a game-changer for the Covenant of Mayors signatories
Until now, getting started with the European City Calculator required cities to gather and manually enter large amounts of data—a significant hurdle for many.
Within SPARKLE, Climact has made it possible to automatically link the EU City Calculator with the Covenant of Mayors’ SECAP forms. For signatories of the CoM who have already submitted their Sustainable Energy and Climate Action Plans, this means they can now seamlessly import their data into the Calculator with just a few clicks.
This update brings clear benefits:
- No need to duplicate data collection – cities can build on existing efforts.
- Instant access to a powerful modelling tool that supports local decision-making.
- Better alignment between reporting (SECAP) and scenario planning (the webtool).
In short, the upgrade removes a key barrier to access, making it easier than ever for CoM cities to use the European City Calculator to support their transition goals.
Join the webinar on 17 June to learn more!
To showcase this major improvement, SPARKLE partners are hosting a webinar on Tuesday 17 June 2025 at 14:00 CEST, open to all interested local authorities.
This is a great opportunity for cities to discover how the EU City Calculator can make their climate planning more efficient, data-driven, and aligned with CoM reporting processes. Don’t miss out on this opportunity!
