As the built environment accelerates its journey towards net zero, the need to accurately measure, assess and reduce whole life carbon has never been greater.
Whole Life Carbon Assessments (WLCAs) are now an established requirement for planning applications across many major local authorities, including the Greater London Authority and several city councils throughout England. At the same time, the UK Net Zero Carbon Buildings Standard (UKNZCBS) and the RICS Whole Life Carbon Assessment Standard (2nd Edition) have reinforced the importance of adopting a consistent and robust methodology for assessing carbon impacts across a building's entire lifecycle.
As demand for these assessments continues to grow, so too does the need for confidence in the professionals undertaking them.
CIBSE Certification's Whole Life Carbon Assessor (WLCA) competency scheme provides independent recognition of professionals who have demonstrated the knowledge, skills and competence required to assess and verify whole life carbon impacts. Operated in accordance with ISO/IEC 17024, the internationally recognised standard for personnel certification, the scheme provides assurance to clients, developers, local authorities and the wider industry that assessments are being carried out by competent professionals.
By recognising competency against established industry methodologies, the scheme helps improve consistency, transparency and confidence in Whole Life Carbon Assessments, supporting better decision-making throughout the design, construction and operation of buildings.
Dave Cooper, 2026-2027 CIBSE President, said: "Professional competence is central to delivering a more sustainable built environment. CIBSE Certification's Whole Life Carbon Assessor competency scheme provides valuable assurance that practitioners have demonstrated the expertise needed to undertake robust assessments, helping clients make informed decisions and supporting the industry's transition to net zero."
Dr Anastasia Mylona, Technical Director at CIBSE, said: "Whole Life Carbon Assessment is becoming an essential part of how we design and deliver buildings that support the UK's net zero ambitions. As expectations continue to evolve, ensuring these assessments are undertaken by competent professionals is fundamental to maintaining consistency, credibility and confidence across the industry."
The scheme offers a range of benefits for both professionals and the wider industry, including:
- Independent recognition of competency against an industry-recognised methodology.
- Increased confidence for clients, regulators and project teams.
- Greater consistency and quality in Whole Life Carbon Assessments.
- Support for organisations responding to evolving policy and planning requirements.
- Professional recognition that demonstrates commitment to best practice and ongoing competence.
With whole life carbon rapidly becoming a cornerstone of sustainable building design and delivery, competent assessors have a vital role to play in ensuring assessments are robust, consistent and trusted.
Professionals looking to demonstrate their expertise in Whole Life Carbon Assessment can apply through CIBSE Certification, a wholly owned subsidiary of CIBSE, and play their part in raising standards across the built environment.
