Elliott serves as the Programme Manager for the Climate Action Planning Programme in Europe and South & West Asia, within the Measurement and Planning Team. In this role, he is working directly with city officials across Europe, South and West Asia to help them develop Paris Agreement compliant climate action plans.

Elliott is currently seconded from Arup, where he works as a senior design engineer on projects across the built environment, working to develop innovative zero-carbon energy strategies for buildings, neighbourhoods and cities, as well as integrating the SDGs and circular economy principles into designs. Recent projects include working with Stockholm Royal Seaport on seasonal energy storage, developing metrics to measure the sustainability of new neighbourhoods for By & Havn, and the zero-carbon design for the UN17 Village in Copenhagen.

Elliott holds a first-class MEng degree in Mechanical Engineering from the University of Warwick, a Masters in Sustainable Development from the University of Cambridge, and a PhD from the University of Cambridge which examined how cognitive biases in workshops can limit rational decision making about the future.
