Grafting Cities – Energy Cities Annual Conference

Valencia, Spain - 26-27 June 2024

26 June 2024 

On the first day, we will dive into transition toward climate neutrality initiatives. Expect in-depth discussions on real-world examples, best practices, and innovative strategies for addressing transition challenges.

> Breakout sessions

Heating and Cooling Decarbonisation

Heating and cooling represents 50% of the energy demand in Europe and 80% of the energy consumption in households. The decarbonisation of heating and cooling is essential to the decarbonisation of our energy sector. The session will look into key success factors that can be learned from cities engaging in the decarbonization of their energy system.​

Participants of the session will benefit from peer-to-peer learning and access customed materials from the REDI4Heat Project.


14:30 – 14:35 Introduction to the session; Nicolas Raimondi, Energy Cities ​

14:35 – 14:45 EU legal framework and Toolbox ; Nicolas Raimondi, Energy Cities

14:45 – 15:40 Identifying key success factors for heat decarbonisation: panel presentation & discussion ​

  • Mr. Stephan Auer-Stüger, Deputy chairman of the climate committee (City of Vienna) ​
  • Dr. Tilmann Rave, Head of the heat planning department (City of Munich)
  • more speakers to be confirmed

15:40 – 15:45 Heat Campaign of the Covenant of Mayors; Allison Le Corre, Energy Cities; 

Beyond Recycling: Waste Prevention in Circular Strategies

Strategies to reuse and recycle materials are best accompanied by measures to reduce resource consumption in the first place. In this session, technical staff and experts from cities will explore the intersection between circularity and sufficiency.​


  • Davide Miceli, Torino (IT)​
  • Mariam Gallée, Grenoble-Alpes Metro(FR)​
  • Matteo Satta, ANCI Toscana (IT)
  • Christina Kalogirou, Ioannina (GR)​
  • Jean-Benoit Bel, ACR+ (BE)

Empowering local authorities in national and EU climate policymaking

Despite cities being at the forefront of climate mitigation efforts, they are often not adequately involved in policymaking processes related to climate action. Throughout the project, EUCityCalc has supported local authorities in engaging with regional, national, and EU decision-makers. 

This session aims to underscore the importance of cities making their voices heard and to share the lessons learned by our pilot cities.​


  • Orlando Paraiba, ENA​
  • Jonathan Crook, CMW​
  • Jaroslav Klusak, SEMMO

From cradle to grave: overcoming community energy challenges in cities

Renewable community projects can come with quite some challenges. During this codevelopment session, participants will be confronted with three pioneering initiatives. Put yourself in the shoes of those cities and remove stumbling blocks around PV or community heat through collective brainstorming. Is this something you can apply in your own town?​


16:15 – 16:25 Welcome and introduction to the Codev methodology; Miriam Eisermann, Energy Cities ​

16:25 – 16:35 Three little-known challenges around PV and heat:

  • Porec (Croatia) : setting up a voucher model for collective energy renovation of a school – Goran Cacic (ZEZ)​
  • Valencia(Spain): setting up PV on a cemetery including vulnerable houses – Arturo Zea (Valencia Clima I Energia)​
  • Utrecht (Netherlands): developing investment concepts for decentralized district heating – Anne-Marie Zwanink (City of Utrecht)

16:35 – 17:05  Cracking the nut: Codev session in three groups moderated by the three challengers

17:05 – 17:20 Presentation on the action actually developed by each city

17:20 – 17:30 Conclusion and lessons learnt; Sara Giovannini, Energy Cities 

27 June 2024

Day two will shift gears towards a day of collaborative learning. Through interactive sessions and dialogues, attendees will have the opportunity to explore new ideas, exchange perspectives, and cultivate synergies between cities.

> Keynote Speech: “Caring for things as well as the livings: the tinkering trail”   

To kick-off the day, Fanny Lederlin, the author of the book “l’Éloge du Bricolage” (In praise for tinkering) will share her experience of how to incorporate “things” (fabrics, waste…) into an ecological approach.  

> Parallel Sessions 

I – Resource-wise cities: rethinking our needs

The issue of wise management of resources (energy, land, water, materials) and their equitable sharing has moved to the top of the cities agenda. It invites us to question our needs and reorganize our infrastructure and services to meet them.  

This session on sufficiency is an opportunity to explore what cities are already doing in concrete terms to improve quality of life and consume resources in a fairer and wiser way. ​

  • Project involved: ADEME


  • Philippe Guelpa Bonaro, Lyon Metropole (FR)
  • Eckart Würzner, Heidelberg (DE)
  • Viesturs Zeps, Riga (LV)
  • Aitor Zulueta, Vitoria Gasteiz (ES) 

II – Local Climate Citizen’s Assemblies

This session will start from examples of cities which have chosen to organize different forms of climate assembly. Same temporality, but different questions and methods of questioning, or even aims (for example Lyon’s climate assembly concerns city agents).

The idea will be to discuss the follow-up to be given and how to integrate (or not) more assemblies into local and European democracy (The European Commission also conducts citizen panels and will react in conclusion). 


  • Ada Amon, Budapest (HU)
  • Gaétane Ricard-Nihoul, European Commission

> Let’s make it work!

The afternoon will be dedicated to sessions to “make it work!”. This event will be made by our members for our members.

During this session, our members will discuss specific challenges they are facing or have faced in the past. Each participant will be able to contribute to the discussion on specific challenges that are of most interest to them.

Below is a list of the first challenges you will be able to contribute to:

  • How to implement a radical change in local policies, involving scientists and stakeholders, to develop adaptation responses to coastal impacts and risks ? (Brest Métropole, France)
  • How do you ensure a coordinated and efficient (well-coordinated) form for laying heat pipes in a city centre? (Assen, The Netherlands)
  • How to make citizens’ assemblies more representative? (Guimaraes, Portugal)
  • How to improve our “business model” to engage citizens in energy transition? (Valencia Energy One Stop Shop)
  • Citizens’ engagement (Turin, Italy)
  • How can we deal with regulatory constraints for an energy efficient and smart district and how can we use the tool ”Smart Policy Lab”? (Örebro, Sweden)
  • How can we encourage homeowners facing energy poverty to undertake renovation work? (Besançon, France)
  • How will you actively involve and convince residents to join a collective heat network? (Assen, The Netherlands)
  • How to cope with Public Tender Procedures when engaging Municipalities in Energy Communities? (ENA, Italy)
  • How to set up legitimacy models for the collaboration between the municipality and local heating cooperatives? (Utrecht, The Netherlands)
  • In a public authority that has grown considerably in recent years, how to maintain dialogue among departments and make cross-functionality a daily reflex? (Metz Métropole, France)
  • How to mobilize cities to adopt and implement SECAPs and climate actions by exploring potential carrots for local decision-makers? (Marmara Municipalities Union, Turkey)
