The Peace in Our Cities campaign seeks to create concrete, participatory, and evidence-based platforms for progress towards achieving Sustainable Development Goal 16, with an initial focus on SDG16.1 (to significantly reduce all forms of violence and related death rates everywhere). To launch the campaign, we are building a coalition of early adopters – including cities, sub-national authorities and targeted thematic partners – inviting them to sign the Peace in Our Cities SDG16 Action Pledge this September.
