Nitrogen footprint for the UK

We are pleased to announce that a journal article entitled "Personal nitrogen footprint tool for the United Kingdom" was published in the journal Environmental Sciences: Processes and Impacts by Stevens et al. This paper presents the results of a per capita UK nitrogen footprint, which can be accessed in the N-Calculator. The paper considers an historical perspective of the UK per capita N footprint and analyzes the impact of different scenarios (such as composting all food waste) on the average UK N footprint.

Journal article describing an institution-level nitrogen footprint model

The personal N-Calculator concept was applied to develop an institution-level model for the University of Virginia.

Published in Sustainability: The Journal of Record, the paper details the methodology of the tool used to calculate UVA's nitrogen footprint.  

Please contact us if you are interested in calculating the nitrogen footprint of your institution. We are currently developing tools that we expect will be available in the spring.    

Launch of the UK N-Calculator

We are pleased to announce the launch of the United Kingdom N-Calculator on 15 May 2013!

This tool will be an important addition to the country N-Calculators. The UK N-Calculator was produced with scientists Dr. Carly Stevens and Sarah Dale (Lancaster University) and Dr. Paul Whitehead (Oxford Unviersity).

N-Calculator Paper Award

The first N-Calculator paper, "A nitrogen footprint model to help consumers understand their role in nitrogen losses to the environment," has been recognized as the best research paper in the journal Environmental Development in 2012.  N-PRINT in the News

N-PRINT Workshop

On December 3-4, 2011, we hosted an N-PRINT Workshop in London, UK.  Representatives from the following 11 countries attended: United States, Netherlands, Germany, UK, Portugal, Spain, France, Finland, Sweden, Italy, and Slovenia.  If you are interested in learning more about this event, please e-mail us at info@n-print.org.    

N-Calculator paper

The first N-Calculator journal article, titled "A nitrogen footprint model to help consumers understand their role in nitrogen losses to the environment," was published in January 2012 by the new journal Environmental Development.   The N-Calculator paper has been featured in the March 2012 issue of the European Commission's "Science for Environment Policy: DG Environment News Alert Serivce."  The article, "Online calculator measures consumers' 'nitrogen footprint'", can be viewed on the European Commission's website.    

The official European launch of the N-Calculator was April 13th, 2011!

A message from the European Nitrogen Assessment:        

Reactive nitrogen* is vital to human life, and yet too much of it is causing serious problems to our health, environment and biodiversity.     You can help make a difference.      

Learn what your personal nitrogen footprint is by answering a series of questions about the food you eat, your transportation habits, and the energy you use.

N-Calculator is just one part of the larger project, N-PRINT.  

The N-PRINT model, which is currently in the development stages, is an integrated nitrogen footprint model that will relate consumers (N-Calculator), producers (N-Producer), and policymakers (N-Policy).  

*Note: Unless otherwise stated, we are referring to reactive nitrogen on this website, and not the unreactive nitrogen that makes up 78% of our atmosphere.
