A new net-zero standard has been presented
The first completed version of the UK Net Zero Carbon Buildings Standard has been published. The standard aims to clarify what “net zero carbon” means for buildings in the United Kingdom. However, what exactly does this standard represent, and how will it affect the construction industry in the future?
The main source: A new standard for net zero buildings
What do the new standards show?
This voluntary, open-access standard has been developed to establish a single, agreed-upon methodology for defining what “net zero carbon” means for buildings in the UK. It contains a set of agreed rules to create a level playing field regarding the meaning of “net zero carbon.” The pilot project was launched in September 2024. This new version retains all the key elements of that project with some technical adjustments.
New additions include a new section focused on the office sector. Users can now verify that their part of the building meets the standard when it is not possible to verify the entire building. It may be done by using either a tenant-only or landlord-only pathway.
The standard covers both embodied carbon, which is emitted directly or indirectly during construction, and operational carbon, which is generated during the use of the building. An annex, “Practical Completion Pathway,” allows verify at the stage of practical completion that the building will meet the standard.
Katie Clemens-Jackson, CEO of the UK Net Zero Carbon Buildings Standard, said: “The standard will provide the clarity and consistency needed for net zero carbon claims and combat greenwashing. Also they provide a clear definition that the industry can work towards.”
How will new net-zero standards affect the building industry?
Celebrating the launch, Will Arnold, one of the authors of the standard who led the work on the embodied carbon section and developed the “practical completion” section, explained that completing the final version included pilot testing of more than 200 projects, as well as reviewing and incorporating more than 3,000 public comments. The work was supported by other organizations. They include: Better Buildings Partnership, BRE, CIBSE, the Institution of Structural Engineers, LETI, RIBA, RICS, and UKGBC.
In the second quarter of 2026, verification will become available. This will allow users to appoint a verifier who can reliably confirm that their building complies with the standard. The standard is collaborating with Bureau Veritas on the final annex. It will cover the verification process and explain how it can be communicated.
Fencyx, as one of the leaders in the UK building industry, follows these changes. We are carefully studying the new guidelines in order to offer our clients products that will comply with the new standards.
