C40’s team of 400+ staff is based in offices in London, in New York, Johannesburg, Singapore, Delhi, Rio de Janeiro, Copenhagen, Beijing and Paris, and individual staff based across 25+ different locations.

The strategic direction of the organisation is determined by an elected Steering Committee of C40 mayors, which is chaired by Mayor Sadiq Khan of London and Mayor Yvonne Aki-Sawyerr of Freetown.
