PEF single score
A single score in this context refers to a product’s overall environmental assessment. The single score is a sum of all the normalised and weighted numbers that a product has scored in each of the impact categories.
So, building on top of all the individual calculations from each impact category, we are able to obtain one figure that expresses the overall environmental impact of a product. This means that we can compare the total environmental impact of different products. Ultimately, it allows us as consumers to make more responsible purchasing decisions. Due to the PEF single score, for the first time, we have a scientific method that allows for comparing and evaluating easily the total environmental performance of two products. The potential effects of this are huge and can be a massive driver for a more environmentally sustainable lifestyle.
