A building-sector specific roadmap must be developed which outlines the steps that will be required to achieve net-zero by 2050. This must cover both operational and embodied carbon emissions from new and existing buildings. A detailed study, using a recognised framework such as Science Based Targets, will be required to establish the necessary timelines and mechanisms for ensuring progress, but this should be completed with urgency. This process will require cross-government collaboration, as well as advice from industry, in line with the Paris Agreement to net-zero by 2050.
