Our new ECV register of MEP products is now LIVE

As the built environment works to meet net zero goals, the industry’s focus is shifting from reducing operational energy use to tackling embodied carbon — the greenhouse gas emissions linked to the materials and construction processes used throughout a building’s life. This shift is an important step forward, but it also highlights major challenges with data quality, transparency, and standardisation that have limited consistent reporting and real carbon reductions.

Embodied carbon makes up around 11% of global CO₂ emissions and typically accounts for 20–50% of a building’s total lifecycle carbon footprint. MEP (mechanical, electrical, and plumbing) products contribute about 27% of a building’s embodied carbon, and this figure can be even higher depending on the manufacturing process and building type. For highly efficient buildings, the share of embodied carbon is often greater still. Despite its importance, embodied carbon reporting for MEP products remains inconsistent and often relies on generic data that doesn’t accurately reflect real products.

To help address this, CIBSE Certification Ltd — a wholly owned subsidiary of CIBSE — has developed the Embodied Carbon Verification (ECV) scheme, based on the CIBSE TM65 methodology. This scheme provides a structured and transparent way to verify embodied carbon data through clear methods, robust processes, and independent assessment. It helps bring carbon considerations into the design process early on, enabling more accurate calculations and better-informed design decisions.

CIBSE Certification is now taking a major step forward with the launch of the first ever verified carbon data products register for MEP equipment. The ECV Register brings together verified carbon data from manufacturers in one trusted source, giving designers, specifiers, and clients greater confidence in their embodied carbon assessments.

The register offers open access to verified data for a growing list of products. This new resource will make it easier for professionals to choose low-carbon solutions, support project compliance, and encourage greater demand for transparent, high-quality data.

“Reliable embodied carbon data is essential if we are to make informed decisions that truly reduce the environmental impact of buildings. The ECV Register represents a significant leap forward for the industry,” said Kieran O'Brien, Director of CIBSE Certification Ltd.
