The UK Green Building Council (UKGBC) has developed a framework definition for net zero carbon buildings to provide the industry with clarity on how to achieve net zero carbon in construction and operation. The framework definition has been produced under UKGBC's own Advancing Net Zero programme, in line and inspired by the ambitions of WorldGBC's global Advancing Net Zero project. From November 2018 to March 2019, UKGBC brought together an extensive range of industry stakeholders, including a task group, to build consensus on a framework definition for net zero carbon buildings in the UK. The primary focus of the framework is to set in place a path to achieve net zero carbon buildings in both construction and operation (in-use energy consumption), whilst beginning to provide direction for addressing whole life carbon in the industry.
