A new Embodied Carbon Verification (ECV) Scheme, based on TM65:2021 and governed by ISO 17065:2012, has been launched by CIBSE to provide assurance around manufacturers’ claims and better support users in their selection of building services products.
CIBSE’s TM65 methodology is very useful for estimating the embodied carbon associated with products in the absence of Environmental Product Declarations (EPDs). Its universality, simplicity and suitability for comparing data makes it attractive to users when undertaking product evaluation and selection. EPDs provide assurance, but use a range of methodologies, making comparison of data difficult. They are considered better suited to mass-produced products, where costs can be easily amortised.
The new ECV scheme, developed by CIBSE’s Certification Body subsidiary, allows manufacturers to demonstrate their green credentials and commitment to sustainability. It also addresses questions of competency, and covers product process and material changes over the three years of certificate validity.
