Aggregates and sand - from virgin marine resources - bulk - loose

Emission intensity of aggregates and sand - from virgin marine resources - bulk - loose. 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]. The consumption of marine aggregate was taken to be the total marine aggregate production. The data has been modelled with the average energy consumption for extracting marine aggregates in the UK. The original data did not use all scope emissions factors instead just scope 1 and 2. The data was therefore used to estimate the full scope 1 2 and 3 emissions. The impacts to produce aggregates has a particularly large variation in embodied impacts. 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.
