The N-Print project strives to leverage the beneficial use of reactive nitrogen while minimizing its negative impacts with an online interactive toolkit.

The N-Print project also has a broader purpose: to reduce global nitrogen pollution, by using the personal N-Calculator tool as a starting point. The overall objectives of the N-Print project are:

  1. Communicate the importance and effects of nitrogen
  2. Develop tools to calculate the nitrogen footprints of individuals, institutions, and other entities
  3. Promote the reduction of nitrogen footprints through the use of N-Print tools
  4. Assess the contribution of an entity's nitrogen footprint to environmental impacts along with the development of regional nitrogen ceilings

Explore the N-Print site to learn all about nitrogen, its interactions with our environment, and ways to appraise and reduce nitrogen pollution.
