	The Product Environmental Footprint (PEF) is a product assessment method aligned to EN 15804+A1 2012 and requires 16 different impact categories to be calculated and reported. The intention of this approach is to harmonise the many different existing Life Cycle Assessment (LCA) standards into a PEF framework that standardises and facilitates better comparison between products. Despite sometimes being used to compare products Environmental Product Declarations (EPD's) were not initially designed for this, as they often use different units of measurement. EPD's are essentially individual statements on the environmental impact of a product rather than comparing like for like.

−	The Product Environmental Footprint (PEF) methodological framework was developed by the European Commission’s science and knowledge service, which relies on the principles of product categories, where product are grouped by similar nature or function. These in turn, generate Product Environmental Footprint Category Rules (PEFCR) which support the overall methodology described and provide more product-specific guidance, potentially seen as more rigid based, to facilitate comparisons in the performance of different products. EPD's also make reference to Product Category Rules ~~as described~~ (PCR's) but are less prescriptive than those within PEF frameworks which are intended to be continually developed as new products are assessed. Both the EPD and PEF methodologies are dependent on a critical mass of uptake which is up until now has been voluntary and driven mainly by market forces, however the introduction of more legislative drivers are continually under discussion.	+	The Product Environmental Footprint (PEF) methodological framework was developed by the European Commission’s science and knowledge service, which relies on the principles of product categories, where product are grouped by similar nature or function.
