Increasing the impact - through Amplifier Cities.


The ambition within our project is to spread our impact across Europe and beyond, to other cities wanting to lead the way in shifting minds, policies and consumption patterns - so called Amplifier Cities. Building on the work of the Lighthouse Cities, they represent a broader coalition of local governments promoting the uptake of sustainable lifestyle challenges by their citizens by:

  • Enhancing the reach of Climate Campaigners,

  • Benefiting from state of the art research into sustainable behavior change,

  • Exchanging knowledge among peers implementing sustainable lifestyle challenges,

  • Contributing to the development of the largest app dedicated to effective sustainable lifestyle challenges.

Amplifier Cities come in many sizes and represent a diverse range of regional, cultural, and demographic contexts. Local governments from any continent are welcome. This is a great opportunity to engage with citizens, and to drive change on the climate crisis in your region!

If you’re a city representative, read more about the initiative or apply directly here.

We’ll be reviewing applications continuously until 2023 and then start a regular program of monthly workshops and exchanges on topics of sustainable lifestyle challenges, using the app effectively, best practices between Lighthouse Cities (e.g.: Dublin, Grenoble, Lahti, Linz, Malmö, Milan, Skopelos, Vilnius) and Amplifier Cities, etc.

For more information, you’re also free to reach out to the Amplifier City initiative leads: Ricardo ( and Sophie (
