RTS EPDs help building contractors, constructors and planners to better understand the environmental issues related to construction products and materials.
The environmental impacts of a product during its life cycle have become relevant information in order to assess the environmental performance of a building or other construction works.
EPDs according to the European standard EN 15804:2012+A1:2013 are voluntary, transparent and well established way to present fundamental and verified environmental information based on life cycle assessment about the environmental impacts of a product or product group.
The indicators referred to in the standard EN 15804:2012+A1:2013 are used to describe the environmental impacts caused during the product life cycle, including:
- climate change impact, which takes account of the so-called carbon footprint
- ozone-depleting substances, which make the ozone layer thinner
- acidifying emissions to soil and water bodies, which damage ecosystems and the built environment
- depletion of non-renewable energy resources and mineral flows resulting from the exploitation of these resources.
An EPD for construction materials can be drawn up for many different applications.
The manufacturer of a construction product can make a declaration
- For the company’s own use, in order to provide information about the environmental impacts of products.
- An EPD can also be made for other companies, in which case the declaration provides the company with essential information from the point of view of the information needs of other companies.
- An EPD can also be made for consumers. In this case, the most technical information can be left out to focus exclusively on what is essential for the consumer (e.g., carbon footprint and energy consumption).
RTS EPDs are made primarily for “business-to-business” use. The declarations are Type III EPDs, i.e. they provide quantified environmental information about the life cycle of a product in order to enable comparison at the building level between products that perform the same function. The life cycle assessment has been carried out in accordance with EN ISO 14044 and the construction sector-specific amendments contained in EN 15804:2012 + A1:2013 (e.g., system boundaries, modularity, etc.).
EPDs shall contain all the information that, in accordance with EN 15804:2012 + A1:2013, must be presented in EPDs in the context of “business-to-business” communications. They can be produced by one or more organisations for one product or a product group containing similar products. Product information and environmental impact calculations shall be presented in EPDs as defined in EN 15804:2012 + A1:2013.
All RTS EPDs shall be verified by a third party. The information contained in them has been checked and proved to be a reliable source of environmental information.
