Minera Skifer is the first in Norway to establish EPD® on a natural stone!
The building sector counts for 40 percent of the energy consumption and greenhouse gas emissions in the world (2015). In order to reach climate goals, materials and solutions that reduce energy consumption in buildings are important. Equally important is to reduce greenhouse gas emissions and energy consumption throughout the lifetime, from raw material extraction, material production, processing, construction phase, the user phase and, not least, demolition and reuse.
Our materials represent highly sustainable building materials. The extraction and processing of stone requires very little energy. Processing are done manually to a wide extend. The distance from the quarry to where the stone is processed, is short. The same applies to the distance to our most common market. In addition, our materials are in need of little to no maintenance, has a very long life and can in many cases be reused. For these reasons our material has very favorable environment numbers compared to most other similar materials. Calculations show that one can assume approx. 400% increase in greenhouse gas emissions by choosing schist produced in Asia rather than produced in Norway (transport to Norway / Oslo included).

The demands to document environmental characteristics in order to be considered as a supplier are increasing. EPD also forms the basis for certification according to BREEAM and LEAD. Awareness of environmental friendly buildings is growing rapidly. Choosing sustainable solutions has become a mark of quality.
An EPD is a thorough and transparent documentation containing:
• Quantitative presentation of results from a life cycle analysis (LCA)
• Information on the method of calculation
• Description of scenarios from “gate to grave”
• Additional requirements spesific for Norway
• Description of the product and technical data
An EPDis a certified Environmental Product Declaration, which reports environmental data over the life cycle of products in accordance with the international standard ISO 14025 and EN15804. The International EPD® System is a programme to develop and register EPDs for any type of goods and services. The system is international, third party verified and deliver flexible source information.
What kind of information does an epd contain?
Information on registration of a product, product category rules, and validity of the EPD.
Specific information such as functional properties and a content declaration of a certain product.
Environmental and performance-related information
A life cycle assessment (LCA) provides information on use of resources and energy as well as various types of emissions.
Additional environmental information
An EPD may contain environmental information additional to the LCA, such as specific information about the user- and the end-of-life phases.
Information about the verification procedure needs to be included
EPD® system advantages:
The International EPD® System is based on the international ISO standards, assuring international use, acceptability and continuity.
No minimum levels or preferences of environmental performance.
Open to all types of products, target audiences and markets.
Based on scientific principles for Life Cycle Assessment (LCA) and approved through independent verification.
Based on specific rules for different product groups (PCR) ensuring that EPDs within the same category of products are calculated and presented in the same way.
Providing a tool for communicating additional information such as social responsibility, quality control and environmental management.
Area of use?
Product-related environmental issues are becoming increasingly important to businesses and public administrations. In practice an EPD is a report containing market-driven and verified facts about the environmental performance of goods and services. One of the most important applications for EPDs is green procurement in the public as well as the private sector, as the EPD provides a fair basis for comparing environmental performance of products.
The EPD methodology includes mapping all the relevant environmental aspects from a life-cycle perspective. This science-based, environmental information can be used for any type of environmental management system and may support other organisational goals in the environmental.
