Life cycle assessments include plenty of valuable information on different inputs and outputs during different phases. To make the information more accessible and understandable to the end-user, a communication tool was developed to summarize the main findings.
This tool is called Environmental Product Declarations (EPD). EPD is predominantly a communication and management tool and should be handled with care in comparative use. Only individual impact indicators calculated and expressed in a standardized form can provide an objective basis for comparison. Also, a product needs to be assessed in the context of its application in a building. Having said this, the only way to correlate environmental impacts of products and environmental impacts of buildings is through LCA-based indicators. EPDs provide the input required to assess the environmental performance of buildings Environmental labels and declarations are then quantified environmental life cycle product information, provided by a supplier and based on independent verification - third party, for instance. The data is presented as a set of categories of parameters. This particular type of LCA for construction products has been developed to provide environmental information from LCA studies in a common format, based on common rules, known as Product Category Rules (PCR), which can vary from country to country.
