The City Amberprint

Twenty-two indicators of the City Amberprint Framework cover three major aspects: energy, transport and ICT. Each of the indicators has a score between 0 (there is a concern) to 10 (no concern). The overall score of sustainability is expressed as Amber City Index (ACI). The ACI is the geometric mean of the 22 indicators. The indicators are constructed in such a way to represent:

  1. Environmental impact of the city, 
  2. Quality of life, 
  3. Risks, for instance interruption of the services provision, 
  4. Actions of the city to improve all three. 

The higher value of an indicator corresponds to the low environmental impact of the city, high quality of life, low risks and proactive actions undertaken by the city. 


The indicators in the City Amberprint are introduced in order to: (i) evaluate current state of sustainability in cities; (ii) identify best practices and share them with other municipalities; (iii) find direct links between the City Amberprint indicators and five aspects of a smart city: water, waste, energy, transport and ICT; (iv) inform decision makers and politicians about the current situation in the city, (v) inform citizens and facilitate public engagement.
