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.

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.
The latest news on the N-PRINT projects:
- The official public launch of the N-Calculator was February 19th, 2011. We launched the N-Calculator at the AAAS Annual Meeting in Washington, DC, at a symposium titled "Global and Local Responses to the Nitrogen Challenge: Science, Practice, and Policy." You can see our press release here, and please contact us if you have any questions.
- The 5th International Nitrogen Conference went very well. We gave multiple presentations on the N-PRINT project and also had three posters. We hosted a 1-day N-PRINT workshop before the conference began, where we discussed the next steps of the project. We also had a footprint calculation table where conference delegates calculated their N footprints.
- The "soft launch" of the N-Calculator tool has been very successful! Many of our contacts (you!) reviewed the tool and provided great feedback on their experience. We are now working on incorporating the suggestions you gave us . Please contact us if you would like to participate in the soft launch.
