This new guidance (CIBSE TM 65) provides a consistent approach for the data required from manufacturers, an embodied carbon calculation methodology for mechanical, electrical and public health (MEP) systems, and the way in which embodied carbon assessments are reported.

Embodied carbon describes greenhouse gas emissions (GHG) – notably including, but not just carbon dioxide – associated with making a product and its installation, maintenance, repair, replacement, and subsequent disposal or recovery, but excluding GHG emissions associated with its operation.

EPDs and TM65 working together

Environmental Product Declarations (EPDs) provide independently verified environmental data for a product across defined lifecycle stages, such as raw material extraction, manufacturing and end-of-life treatment.

 

This information allows consultants and engineers to incorporate verified product data into lifecycle assessments and building sustainability frameworks.
