Why a nitrogen footprint?

Reactive nitrogen is vital to human life; it is necessary for food production and it is also a by product of energy consumption. Too much reactive nitrogen in the environment causes a cascade of environmental problems that negatively affect human health in addition to the environment. Small changes in lifestyle choices can have a big effect on your nitrogen footprint and your impact on the environment.

What types of nitrogen footprint tools are available?

Use the N-Calculator to calculate your personal N footprint. The N-Institution tool is being designed to help universities and other institutions calculate and reduce their nitrogen footprints.
