Aggregates and sand general UK - mixture of land won - marine - secondary and recycled - bulk - loose

Emission intensity of aggregates and sand general UK - mixture of land won - marine - secondary and recycled - bulk - loose. This is an estimate of a market average aggregate. It models a mixture of 64.2% land won 27.5% recycled and secondary and 8.3% marine aggregates. Consumption statistics have been taken from a report by British Marine Aggregates Producer Association a member of the Mineral Products Association (MPA). [Tenth sustainable development report for the British marine aggregate industry Dec 2016]. These results are sensitive to the embodied carbon of secondary aggregates which is a material where data would benefit from improvement. If you know the specific type of aggregates you will use then it is recommended to use a more specific category of aggregates. The source does not clarify if the kgCO2e value is calculated using either IPCC Fourth Assessment Report (AR4) or IPCC Fifth Assessment Report (AR5) methodologies.
