If you followed our earlier posts about ecological footprints, you'll probably find Ecological Footprint Network pretty interesting. And if you're into this stuff, well, this is the motherlode.

"[T]he Ecological Footprint has spread far and wide. Thousands of organizations and individuals, including cabinet ministers, on all continents have used the tool to call for policy choices that are consistent with the globe’s ecological constraints.... But many Ecological Footprint projects around the world are based on older or inconsistent methods, producing results that are not comparable. This confusion of measures may eventually erode the concept’s credibility and reputation, and undermine its ability to build momentum for an economy that uses natural capital in socially just and ecologically sustainable ways.

"In order to enhance the rigor, credibility and impact of this thinking worldwide, Mathis Wackernagel and his colleagues are setting up the Ecological Footprint Network that brings together the worldwide community of Footprint practitioners from academia, governments, business, and organizations."
