This paper deals with stakeholders’ decisions within energy neutral urban redevelopment processes. The decisions of these stakeholders during the process will make or break energy neutral ambitions. An extensive form of game theory gave insight in the behavioural differences of stakeholders regarding energy neutral ambitions and changing legislation. This paper shows that new legislation regarding spatial planning slightly influences the behaviour of stakeholders. An active behaviour of the municipality will still result in the best outcome. Nevertheless, the municipality becomes more powerful when acting passively and can make use of planning tools to govern towards energy neutral urban redevelopment. Moreover, organizational support, recognizing the necessity for energy neutrality, keeping focused and collaboration among stakeholders are crucial elements to achieve the objective of an energy neutral urban (re)development.
