Putting a price on phosphorus: links and publications


  1. Phosphorus is mined and processed into fertilizer along with other nutrients like potassium and nitrogen.
  2. Applied to the fields, it is incorporated into vegetables and sold direct or as animal feed.
  3. Phosphorus leaks from agriculture into waterways and is exported to shops as food.
  4. Consumers purchase food for consumption.
  5. Phosphorus leaves the body mainly as urine.
  6. Sewage is processed at water purification plants.
  7. Some phosphorus is dumped as waste from purification, some ends up in waterways.
  8. Eventually phosphorus travels to the sea.
  9. Some phosphorus can be recovered from the sea-bed, most remains in the sea.

Phosphorus is one of the elements implicated in the work done by Rockström et al at the Stockholm Resilience center.

We are close to exceeding nature’s boundaries for the phosphorus cycle.

In two other boundaries, climate change and nitrogen cycle, two other elements, carbon (from fossil sources) and nitrogen are implicated.  These pollutants are different as the diagram below shows:

Thress pollutants

Because of this, the application of where and how to apply fees needs careful consideration. The diagram below shows the plethora of  points of extraction of fees and taxes that could be adapted.

A recent publication by the Swedish Sustainable Economy Foundation outlines how a flexible pollutant fee can be levied on phosphorus entering the market economy. Raising the fee at regular intervals until the import and or pollution stops, the fees are returned to the market as returns to tax payers.
