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 the IPCC Fourth Assessment Report (AR4) or IPCC Fifth Assessment Report (AR5) or IPCC Sixth Assessment Report (AR6) methodologies.
