Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what is their estimate of the amount that marine aggregates contribute to the sand and gravel requirements of England and Wales.

Table 5 of the Monthly Statistics of Building Materials and Components published by the Department for Business, Energy and Industrial Strategy shows that in 2016 there were 50,153,000 tonnes of sand and gravel sold in England and Wales, of which 11,770,000 tonnes were marine dredged – which is equivalent to 23%.
