Scrutiny on carbon accounting in the built environment is increasing and is highly reliant on supply chains improving transparency of verified GHG emissions data. Carbon emissions associated with building services are notoriously absent. They are becoming increasingly relevant because of the recent increase in retrofit activity driven by carbon targets and MEES legislation, resulting in MEP making up a larger proportion of embodied carbon at the product stage.

In 2021 CIBSE published TM65 Embodied carbon in building services: A calculation methodology to increase knowledge and facilitate research related to whole life carbon.

This panel explores this methodology, and proposes further solutions, to better improve transparency around the embodied carbon of building services.
