All the measures and strategies implemented so far in the decarbonisation of buildings have been aimed at reducing GHG emissions in the use phase of buildings. The Building Life initiative proposes a roadmap drawn up in collaboration with representatives of all the sector’s agents in order to make more effective progress in the transformations yet to be undertaken. In this session, the challenge of systemically undertaking the decarbonisation of all phases of the building’s life cycle in order not to exhaust the carbon budget available by 2050 is put forward. During this session, the latest advances in the proposed roadmap will be presented, following the participation process in which more than 250 entities have already participated.
