Why Material index is introduced in BASIX but does not have a compliance target?

Construction materials contain embodied carbon emissions, that is the gases released due to the extraction of raw material to the fabrication of the final product. Because of the revealed complex relationship between the proposed Material standard and the existing thermal performance standard, the standard for embodied emissions from building materials will not apply for further data gathering and assessments. The target for the Material category will likely be available for the next BASIX standard in 2025.
