Natural Stone the environmental choice 

Natural stone is one of the simplest and most enduring building materials available. It is extracted from the ground, cut to size and finished for its intended use, with comparatively little processing required to turn the raw stone into a finished building product.

Unlike many manufactured materials, natural stone does not need to be fired in a kiln or created by mixing multiple ingredients. There is no chemical manufacturing process, helping natural stone achieve a low embodied carbon footprint.

Naturally low in embodied carbon

The carbon footprint of a building material begins long before it reaches a construction site. Extraction, processing, manufacturing and transport all contribute to embodied carbon.

Natural stone requires relatively few production stages. Once extracted, it is primarily cut and finished using mechanical processes. This limited transformation helps reduce the energy required during manufacture and makes natural stone a strong choice for low carbon construction.

The environmental impact of different stones can still vary. Extraction methods, factory energy, production efficiency and transport distance should all be considered. Independently verified Environmental Product Declarations provide the most reliable way to assess and compare this information.

Our independently verified Environmental Product Declaration provides transparent environmental data for Portland Stone extracted and manufactured by Albion Stone.

Made to last

Natural stone has been used in buildings for centuries. When correctly selected, detailed and installed, it can provide an exceptionally long service life while requiring relatively little maintenance.

This durability is an important part of its environmental performance. Materials that remain in use for longer reduce the need for replacement, repeated manufacturing and further consumption of resources.

Suitable for reuse

Stone can often continue to serve a useful purpose beyond the life of its original building. It may be carefully removed and reused in its existing form or recut into new masonry, flooring, paving and landscaping products.

This ability to recover and reuse natural stone supports a more circular approach to construction and helps preserve the carbon already invested in extracting and processing the material.

The value of locally sourced stone

Transport can form a significant part of a building material’s carbon footprint. Choosing natural stone extracted and processed closer to the project can considerably reduce transport emissions.

Local sourcing can also provide greater transparency over where a material comes from, how it is extracted and how it is manufactured. It supports local employment, specialist skills and domestic manufacturing while reducing reliance on long international supply chains.

Our analysis of how local sourcing can reduce transport carbon by 89% demonstrates why the distance between extraction, manufacture and the finished project should be considered when specifying natural stone.

A natural choice for low carbon construction

Natural stone combines minimal processing, low embodied carbon, proven durability and the potential for reuse. When responsibly extracted, efficiently manufactured and appropriately sourced, it offers architects, specifiers and contractors a practical low carbon building material for façades, masonry, flooring, paving and landscaping.

Environmental performance should always be supported by reliable evidence. Project teams should consider Environmental Product Declarations, responsible sourcing certification, expected service life and transport distance when comparing natural stone with alternative materials.
