The environmental justice movement began as a reactionary one, fighting the discriminatory siting of point source pollution. It has grown to be multi-faceted and proactive, and covers inequities in road safety and access to public spaces. We now have the tools to build these ethics into the way we design cities. TCAT’s Active Neighbourhoods team works to embed under-represented voices in the planning of cities. Participatory Design Consultant Car Martin explained the Active Neighbourhoods approach at the World Design Summit, held in Montreal in October 2017.
