The GSMA Mobile World Congress usually takes place in February but occasionally the show occurs the first week of March. The location is the Fira Gran Via venue in Barcelona, Catalonia, Spain. Annual attendance is generally between 80,000-90,000 people. Up until 2006 the event took place in Cannes and was known as 3GSM World. Attendees represent more than 200 countries from across the globe.
GSMA Mobile World Congress 2015 took place between March 2 and March 5, 2015. The theme was The Edge of Innovation and was attended by more than 93,000 participants.
The announced dates for Mobile World Congress 2016 are February 22 - February 25, 2016.
In 2014 the GSMA announced that the event was striving to become carbon neutral. In July 2014, it was announced that Mobile World Congress 2014 was indeed the largest conference and exhibition to be certified as carbon neutral through PAS 2060, an internationally recognised certification system. To achieve this certification, the GSMA calculated Mobile World Congress’ carbon footprint; developed a footprint reduction strategy; and offset emissions that could not be avoided. The certification marks the latest step in the GSMA's long-standing and continued commitment to preserving the environment.
Other green initiatives at Mobile World Congress include solar device charging, reduced waste of printed materials, encouraged the reuse and recycling of materials at the venue, and utilised digital signage and electronic tools.
