Mark’s aim as Executive Director is to ensure that C40 Cities is equally focused on science-based climate action and political leadership for climate justice. C40 has grown dramatically in scope and ambition under Mark’s tenure and its 300 staff now support nearly 100 of the world’s leading cities, representing around 700 million residents.
Mark has been named one of the world’s most influential leaders driving climate action as a ‘defender’ by TIME as part of its inaugural TIME100 Climate list. Prior to joining C40 Cities, Mark was a director at pioneering engineering and design firm Arup; and previous to that role, he was a senior adviser to the Mayor of London. Outside of work, he can usually be found either up a mountain or proclaiming the discovery of a great new band.
