The Science





Plnktn is developed by The Green Monks in close partnership with Global Footprint Network.

The results and personal calculation algorithm were developed based on the Global Footprint Network's Consumption Land Use Matrix ( and derived from National Footprint Accounts (, the most widely used source of Ecological Footprint data.

Underlying data, theory, and concepts are consistent with the Ecological Footprint Calculator ( although questions and results may vary.

Supplemental background reference data for the calculations is based on average consumption patterns for middle- and high- income countries and average lifetime Ecological Footprint for product categories.
