The Global Footprinting Network has plenty of background information and maps to illustrate and explain the footprint concept (here)
A short 3 minute video by Assoc. Prof George Ganf on the global footprint, climate change and population.
You used to be able to order information packs about the ecological footprint concept from the SA Government Sustainability and Climate Change Division (+61 8 8204 2999) but it looks like they have closed that down, or at least all teh web links are gone.
You used to be able to get a fantastic DVD/download which explains the concept, from the Victorian Government EPA. They have scrapped it. Go here to complain. However, someone has uploaded it to youtube so you can watch it there
Many calculators have been taken offline since I wrote this page, but you can find one for Australia here
Perhaps because climate change is becoming the most publicised environmental issue, there are lots of carbon footprint calculators now, including this one and a collection sent to me by Carla from doubleglazed.com as part of their "52 strategies to lower your carbon footprint" page- thanks!
