On December 13th, we had the pleasure of talking with Joan Clos, Secretary General of United Nations and Executive Director at UN Habitat (2010-2017). This session was broadcasted live through Twittter, we thank everyone who interacted with us through social media during the event. We discussed with Mr. Clos some of the key topics which will be addressed during the sessions at SUM Bilbao 19 such as the crucial role which cities play nowadays in achieving a more sustainable mobility.
