Question to the Ministry of Housing, Communities and Local Government:

To ask His Majesty's Government what assessment they have made of the benefits of stone as a relatively low-carbon building material; and what steps they are taking to promote research and development of its use.

Depending on how stone is quarried and how far it is transported, it is likely to be a relatively low-carbon material. We are carrying out research into the impact of measuring embodied carbon and methods of reducing it across building types - including the contributions that could be made by different material choices. We will set out further announcements in due course.
