Cities have the potential to inspire, connect and empower people on issues that concern them. In the cities we live in, climate action is needed and communication is more necessary than ever. C40 Cities Network connects 97 of the world’s greatest cities, representing more than 700 million citizens, to take climate action, leading the way towards a sustainable future. The Network released the C40 Climate Action Planning – Communications Toolkit, an easy-to-use communication handbook that touches on the human, everyday side of things by proposing new ideas, strategic communication knowledge and instantly understandable guidelines for planning climate action locally. Sympraxis Team is proud to have participated in its creation, together with the partner agencies-members of the DoNotSmile Network (DNS) of Ecoavantis and Creative Concern.
