Your Nitrogen Footprint

Click the footprint below to calculate your personal nitrogen footprint.

Use the Nitrogen Footprint Calculator (N-Calculator) to calculate your nitrogen footprint. N-Calculators are currently available online for the United States, the Netherlands, Germany, and the United Kingdom. N-Calculators will soon be available online for Austria and Japan. Tools are in development for additional countries, including Australia, China, Denmark, and Tanzania. If the N-Calculator is not yet available for your country, then you can still calculate your N footprint! Just select the country that is most similar to your home country.

Please note that, depending on your network connection speed, it could take a couple of minutes before the application is fully loaded. 

The N-Calculator is a tool that allows individuals (you) to calculate their nitrogen footprint.  The tool can also be scaled for use by communities, organizations, or countries.  When using the N-Calculator, you are asked questions about your resource consumption in the following sectors:

  • Food consumption
  • Housing
  • Transportation
  • Goods and services

The N-Calculator, which starts with the average per capita consumption of these four categories in a country, is then scaled to the individual based on the user’s answers to the questions.  The N-Calculator then estimates the nitrogen lost per unit of per capita resource consumption. The figure below shows the average per capita nitrogen footprint in the United States (adapted from Leach et al. 2012).
