Transforming An Existing City into 0 emissions The Institute for Advanced Architecture of Catalonia is involved in a research project to transform the city of Barcelona in a Zero Emission city. To make that possible, the students were asked to map the city from an energetic point of view, and then propose strategies to make the goal possible. This booklet shows the CO2 mapping process for the barrios of La Sagrea, Congrés, Navas and Camp del’Arpa, and the consequent proposals to reduce them.
