City Lab Barcelona studies the impacts of urban projects, policies and interventions using formal experiments and direct observation. We engage in applied research, direct action and partnership to learn about city dynamics.  

We undertake research projects that entail impact evaluation, tactical urbanism, experimentation or direct observation. Our mission is to generate applied knowledge that can accelerate the transition to sustainable urban planning and design.   

City Lab Barcelona is a research group at the Institute for Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB).
