Latest CO2e values for concrete
As part of the Concrete Industry Sustainable Construction Strategy our commitment is to provide the most transparent life cycle assessment data which is compliant with the codes and standards. This is reflected in the recent update by the cement sector of Embodied CO2e of UK cement, additions and cementitious material. This replaces the previous version which was published in 2015.
The embodied CO2e figure for CEM I in the updated information shows a 5.8% reduction in emissions compared to the 2015 information.
The current information maintains the cradle to gate boundaries so does not currently include any benefit (in terms of CO2 reduction) from the recarbonation of the cement during the lifecycle of concrete or any emissions from transport to the customer. All of the reduction shown from the previous version is a result of action taken by UK cement producers to reduce the embodied CO2e of cement. No offsetting has been used towards this reduction.
Previous versions of the factsheet underpinned the data for cement and concrete in the ICE databases developed by the University of Bath. Since that time PAS 2050 has become recognised and revised as a reference point for greenhouse gas emissions of products and services in the UK. The recent 2011 revision also recognises the prominence of the EPD methodology EN 15804 for construction products, published in 2012. The PAS 2050 document has been considered, and elements included, in ISO 14067 which is the international standard for Greenhouse Gas emissions of products and services.
In producing this updated information the principles of all the relevant codes and standards have been considered and where technically possible have been included in the current methodology. Despite the challenging economic conditions, the factsheet shows that the cement sector has continued its programme of emission improvements.
