The B3 Conference aims to launch an unprecedented momentum of bio-based building across local and regional authorities worldwide. Over two days, creative and innovative initiatives of varying scales – from a building construction project to a regional development program - will be presented by project leaders, experts and professionals from both the public and private sectors to delegates from across the world.

The conference will be held on Tuesday, November 5th and Wednesday, November 6th, 2019 at the Paris Region headquarters. It will be followed by a 1-day guided tour highlighting bio based building related projects in and around Paris, on Thursday, November 7th.
