Phosphorus is a vital element that is currently being consumed in an unsustainable manner. The element is crucial to humanity's food supply systems. In this study, the amount of phosphorus required to meet an average Swedish household's annual consumption was calculated. The method for the report was based on a literature study along with calculations. The data collection was structured into five categories and 15 subcategories, each representing an influx of phosphorus to Swedish households. The study found that, based on these subcategories, the total phosphorus footprint for Swedish households' annual consumption is 16.36 kg. Food consumption accounts for the largest proportion of this footprint and amounts to 14.23 kg. Wool is the subcategory for which the highest concentration of phosphorus is consumed for each weight unit. Wool consumes about 0.43 kg of phosphorus for every kg of product. The report also examines and discusses various scenarios for how much phosphorus that could be saved if Swedish households were to follow a certain type of diet. Furthermore, a comparison was made between the phosphorus footprint of this report and other studies. The Swedish household's phosphorus footprint in this report is considerably higher than the corresponding phosphorus footprint in other studies. It is therefore important to consider the different definitions that the different studies use for their respective phosphorus footprint.
