The Department of Transport of the Basque Government is currently working on the draft bill of the Sustainable Mobility Act. The draft bill establishes a model that is committed to active mobility (on foot or by bicycle), promoting public transport over private vehicles, the interoperability of public transport tickets in an integrated intermodal system, promoting a sustainable mobility approach based on urban planning, and promoting rail transport. At the SUM BIO21, we shall bring together representatives from the public, private, business and academic sectors to share and contribute ideas and knowledge. Only then will we be able to build the mobility of the future from a sustainable perspective.
