The request to construction product manufacturers for Environmental Product Declarations (EPD) is becoming more frequent. Whilst large companies may have commissioned EPD for their products for some years, many others, especially SMEs, find this a new and confusing journey. This Briefing Paper aims to provide guidance to getting started in obtaining an EPD by giving an overview of the process involved and the data that will be required. (This paper is not about what is an EPD – information about which can be found in other CPA Briefing Papers).
