CIBSE welcomes the growing leadership shown by heat pump manufacturers in advancing decarbonisation across the built environment. With increasing focus on whole-life carbon, it is encouraging to see the industry taking measurable steps to improve transparency and accountability in product performance.
Many manufacturers are already applying CIBSE TM65 to calculate and better understand the embodied carbon of their heat pump products. Building on this, Mitsubishi Electric and Fujitsu General Air Conditioning UK have taken a significant step forward by achieving independent certification through the CIBSE-run Embodied Carbon Verification (ECV) scheme.
Recognised as early adopters of the scheme, the two organisations have certified approximately 170 heat pump models, which are now listed on the ECV Register—the only source of CIBSE-verified TM65 embodied carbon data. This milestone marks a significant advancement in providing credible, standardised data to support more informed decision-making across the supply chain.
Developed by CIBSE Certification, CIBSE’s wholly owned subsidiary, the ECV scheme is setting a new benchmark for transparency and rigour in product embodied carbon reporting. By combining robust methodologies with independent verification, the scheme helps ensure that claims made about product performance are both reliable and comparable.
This progress demonstrates what leadership looks like in practice: a commitment to robust data, independent validation and continuous improvement. As the industry works towards reducing whole-life carbon emissions, initiatives such as the ECV scheme will play a critical role in supporting the transition to a more sustainable built environment.
Professionals across the sector are encouraged to explore the ECV Register to access verified embodied carbon data and support more informed specification and procurement decisions.
