Our mission is to help end ecological overshoot by making ecological limits central to decision-making. By promoting data, tools and analysis linking resource constraints to economics and well-being, Global Footprint influences major investments and policy shifts to support global sustainability. We work with national governments, investors, and opinion leaders to achieve our vision: all people live well, within the means of nature. 

Two of our most popular initiatives are Earth Overshoot Day and our Ecological Footprint calculator. Our online calculator lets users measure their impact on our planets resources and then offers simple lifestyle changes to reduce their Footprints. Measure your own Ecological Footprint at www.footprintcalculator.org. Our Earth Overshoot Day campaign highlights the need for the entire human population to live within the means of our planet.
