Product Environmental Footprint (PEF) is a new method for measuring sustainability performance developed by the European Commission in cooperation with companies and sustainability experts. PEF is a new and improved method that measures the environmental performance of any service or good throughout its Life Cycle (taking into account all the supply chain activities). The PEF methodology is very similar to a Life Cycle Assessment (LCA) and the common LCA calculation can, therefore, be used for the PEF calculations. However, PEF will be more stringent in its rules than a normal LCA, due to the PEF Category Rules (PEF-PCR’s). Additionally, as they have been further specified, defined, and determined by the European Commission, the PEF assessments will be more comparable, and more suitable for benchmarking products and/or services than previous LCA’s.
