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

To ask Her Majesty's Government, further to the 2050 Net Zero target, whether they have assessed the levels of embodied carbon contained in (1) synthetic, and (2) nature-based, insulation materials.

The Government has not undertaken such an assessment. The Government continues to take forward work to mitigate carbon emissions through measuring and reducing the embodied and operational carbon of the buildings and infrastructure it funds, and within the construction supply chain.
