We would like to assess the impact that the CIBSE TM65 Embodied carbon calculation methodology is having within industry. We want to hear from manufacturers and consultants about how they are utilising TM65, and how it has impacted approaches to whole life carbon assessments.

Below are two questionnaires designed to gather information from consultants and manufactures. 

Please take the time to complete the one most relevant to you.

The focus in the construction industry is moving from operational carbon emissions to whole life carbon emissions, including those that occur during the manufacturing, transport, installation, and disposal of the building services equipment. In January 2021, CIBSE launched TM65 Embodied carbon calculation methodology.

Unlike the other big embodied carbon emitters such as the building structure and envelope, the limited servicing life of the building services products means that their total lifecycle embodied carbon can be a yet greater proportion when the whole life-cycle of the buildings are considered. Ongoing grid decarbonisation and improvements in manufacturing processes have also led to rapid changes in the proportion of embodied carbon in MEP products. This had led to gaps, where embodied carbon data is not fully captured by Environmental Product Declarations (EPDs). TM65 aims to fill these gaps by engaging the supply chain and encouraging manufacturers to report lifecycle environmental impacts of their products on a regular basis.

If you have any questions or feedback, please contact Juliet Rennie, CIBSE PR and Communications Executive via [email protected]
