CIBSE said heat pump manufacturers are taking further steps on embodied carbon transparency as whole-life carbon gains attention across the built environment. Mitsubishi Electric and Fujitsu General Air Conditioning UK have achieved independent certification through the CIBSE-run Embodied Carbon Verification (ECV) scheme.
CIBSE said many manufacturers are already using CIBSE TM65 to calculate and understand the embodied carbon of heat pump products. It said the two companies are early adopters of the ECV scheme.
According to CIBSE, the two organisations have certified about 170 heat pump models. These models are now listed on the ECV Register, which CIBSE describes as the only source of CIBSE-verified TM65 embodied carbon data.
CIBSE said the milestone supports more informed decision-making across the supply chain by providing credible, standardised data. The ECV scheme was developed by CIBSE Certification, CIBSE’s wholly owned subsidiary.
CIBSE said the scheme aims to set a benchmark for transparency and rigour in product embodied carbon reporting by combining robust methodologies with independent verification. It also encouraged professionals across the sector to use the ECV Register when making specification and procurement decisions.
