What is Environment Product Declaration (EPD)?
An Environmental Product Declaration (EPD) is a standardized document informing about a product's potential environmental and human health impact. EPDs are called Type III environmental declarations which are Product Specific
The EPD is produced on the basis of Life Cycle Assessment (LCA) calculations and provides a quantitative basis for comparison of products and services.
The key benefit of EPDs is that they allow architects and specifiers to compare products in terms of their whole-life sustainability – an increasingly important consideration as clients demand compliance with certification schemes such as LEED.
Types of EPDs
Depending on the number of life cycle stages covered there are three types of EPD.
Type 1: “cradle to gate”
1. The first contains impact values about stages and is called “cradle to gate”, which means information for the product from the raw material extraction and processing until the end of the manufacturing process.
2. The product compares with other similar products and shows how environmental characteristic.
Type 2: “cradle to gate with options”
1. The second type of EPD is “cradle to gate with options”, which includes all the information relevant for the first type plus other optional information for the end-of-life stage such as impacts during demolition and waste disposal stages.
2. The Manufacture self-evaluates his products and with his label the manufacture guarantees that his product guarantees certain self-declared requirements.
Type 3: “cradle to grave”
1. The third type of EPD is “cradle to grave” and provides environmental impact information about the complete life cycle of the product, including installation into the building, maintenance, replacement, and end of life stages. Also reuse or recycle value of the product at final stage may be included in any type of EPD.
2. These Covers single product from a manufacturer which has fulfilled all the PCR (Product Category Rules). The EPD is calculated as whole product in LEED.
Validity: An EPD normally has a Validity of 5 years
