To achieve this, our project also developed a prospective modelling approach: the European City Calculator web tool. This open-source tool provides cities with a sectoral outlook on the type and ambition of measures they can take by:

• Performing real-time simulations that build a direct understanding of the key measures and levers of the low carbon transition.
• Raising awareness of the whole energy system and its dynamics, all greenhouse gas emissions, and the associated resources and socio-economic impact.
• Following the steps to select measures, build scenarios and analyse them to calculate GHG reductions and their associated costs.
