About JustETrans

The energy transition affects everyone. It is therefore important to make decisions that help to achieve climate goals in a fair way. By giving justice a place in the computer models that are often used to devise solutions, we develop a methodology that makes this possible.


Energy transition measures should not only effectively reduce CO2, but they should also be just. Deciding what technologies to use where and when, who should pay or profit, and who should be involved in deciding so, is far from easy. This project aims to support coordinated and robust decision-making for a just energy transition, by developing an innovative participatory multi-modelling approach.


JustETrans is a collaboration research project between Delft University of Technology and Leiden University. The project adopts a transdisciplinary approach, involving engineering, modelling, social, economic disciplines and a wide range of public and private actors to co-produce the participatory multi-modelling approach.


JustETrans is build up of four parallel PhD projects. These projects feed into each other and come together in case studies.

Project 1 - Conceptualisation of Energy Justice

How can we understand the growing and diverse calls for justice in the energy transition? What views do different actors have on how the transition should become a just transition? And how do these views shape energy policies, models and participatory decision-making? Sander ten Caat finds structured ways of comparing these views on justice to see how these conflict or complement each other, and to allow for their inclusion in energy models and decision-making processes.

Project 2 - Integration into a multi-model ecology

Models are increasingly used for decision-support when formulating energy transition policies.
Can these models be extended to support policy-making for just transitions? What needs to change in existing models and modelling processes to enable policy-makers to bring about just outcomes? How can we integrate justice into models?

Through a systematic exploration of such questions, we aim to enable design of just energy transition supported by models that are more cognizant of their justice implications.

Project 3 - Developing a participatory methodology

An important part of participatory multi-modelling process regards designing the underlying social processes. This requires a good understanding on why, when and where in a policy process one should apply participatory multi-modelling.  If these matters are clear, design can be made focusing on whom to involve, how to involve people and how to design and measure these processes.  Aim is to test both an eventual methodology and measurement using serious gaming and cases with consortia partners.

Project 4 - Change

Does anything change when actors interact and exchange ideas and perspectives on modelling justice? Do the models that come out of this interaction reflect justice conceptions differently? And how does this impact decision-making? Annemiek de Looze aims to answer these questions by analysing the impact of participatory practices and knowledge transfer on justice in models and decision-making.

The energy transition is a complex challenge involving technological, political, behavioural, and social transformations. In this transition, social conflict frequently occurs regarding disagreements over how, when and where energy should be produced, transformed or transported. Recent literature argues for the potential value of social conflict when conflict is used to draw lessons and improve policy and projects to fit with the concerns of stakeholders. However, research in which the actual positive repercussions of multiple social conflicts are evaluated on a systemic level is lacking. In this paper we aim to empirically investigate if and how social conflict leads to institutional change. Our first research question is how institutional change as a result of social conflict can be assessed. To answer this question, we develop a framework combining the Ecologies of Participation framework with institutional change literature to evaluate the value of social conflict on institutional change regarding the objects (the ‘what’), subjects (the ‘who’), and models (the ‘how’) of participation. We apply this framework to the case of onshore wind energy in the Netherlands. Through a document analysis and semi-structured interviews, we answer the second research question: (how) did institutional change result from conflict occur for the Dutch transition to onshore wind energy between 2013 and 2022? We present our findings on which institutional changes occurred and discuss the dynamics allowing for or hindering institutional change. Our research contributes to a growing necessity to combine a systemic analysis of complex socio-technical processes with concrete measurements of change.

Designing local energy transitions is becoming an important question for local governments all around Europe. Negative perceived impacts of energy projects on local communities have frequently sparked opposition. Citizen resistance is often fed by feelings of recognition, distributive or procedural injustice. To give policymakers insight into these, (hidden) injustices, we designed the “Just Solar Panels” serious game. The game aims to make players experience how it feels to be participating in a participatory process from the perspective of different archetypes. The player are expected to balance daily personal tasks, needed to stay happy with processing and acting upon municipal information in a limited amount of time. The stated aim is to maximise points that represent general wellbeing The roles and tasks are designed in a way that are unfair in a non-obvious way. This mimics reality where citizens with the same information and opportunities to participate may not be able to do so because of systemic injustices. 

The game was played in three sessions with students, academics and industry and policy experts. The debrief was focused on eliciting experienced inequalities between players in the game and relating these to reality. The game successfully allowed players to experience injustices and relate these to reality, increasing their understanding of how seemingly just participatory processes can be unjust. In the future, the game should be further developed to enhance its use as a tool for learning and building capacity for change in organizations towards a more just local energy transition.
