Engaging decision makers for an urban underground future

Abstract This paper will look into the topic of how decision makers can be engaged in the development of urban underground space. It will ask the question whether it is the decision makers we need to focus on, or if the development of urban underground space involves further stakeholders. The paper will look at the way the ITA Committee of Underground Space has worked in advocating underground space for the past 8 years. The question will also be asked where we stand 100 years on from the first advocates of underground urbanism.
