Natural Stone and Sustainability

The oldest rocks on Earth have been dated at some 4 billion years old. The very mechanism of earth building is ultimately a continuous process of rock formation, consumption and sustainable re-generation. Natural stone used on construction projects provides the timeless essence of solidity, quality and prestige and mirrors the basic mechanism of earth building as stone is worked for new build projects and subsequently reused with time.

But how can the true 'sustainability' of a material like stone be measured? How can you tell if the materials and components being specified for a project have a low environmental impact?

Green specifications are constantly changing as new materials are developed and our understanding of what it means to be sustainable evolves. Although the details of green specifications are not fixed, there is a general consensus that for a building to be sustainable it needs to use materials that: improve energy efficiency, reduce waste and pollution, conserve natural resources such as water and wood, are non-toxic, use renewable energies and have a long life-span. Natural stone is typically one of these materials.

The Green Guide (www.thregreenguide.org.uk) gives manufacturers and producers the opportunity to examine their environmental credentials and gives designers and specifies online access to a wealth of independent information.

Components are rated on a system that reflects the best environmental performance / least environmental impact across the entire life cycle, within comparable specifications. In general natural stone performs very well across a range of categories in which it is included in the Green Guide.

Stoke Ground Bath Stone generally performs as an 'A' or 'A+' rated component. In fact nearly half of all stone related components achieve an A or A+ rating and well over half are rated C or above.

Stone is therefore a truly sustainable material and merits its place in any sustainable development.
