Embodied carbon in building services: A calculation methodology

CIBSE’s TM65 provides a calculation methodology to assess the embodied carbon in products linked to mechanical, electrical and public health (MEP) systems.

Embodied carbon is understood as the greenhouse gas emissions (GHG) associated with the making of a product, its installation, its maintenance, repair, replacement, and then its end of life. It covers the whole life cycle, excluding operational aspects and the potential recovery, reuse or recycling of materials.

When using TM65 reports to compare products, please consider the amount of CO2 together with the expected product lifespan. A Stoane Lighting product's life cycle is 25 years,
