How much “nature” is available?
With 6.3 billion people (2003)
Global average availability of bioproductive land + sea area
= 1.8 global hectares/person
Footprint components
Fossil Fuel Built-up Waste Food Fibres absorption
Human Demand (Ecological Footprint) Ecological Supply (Biocapacity)
Footprint Areas for: Biocapacity Areas:
Growing Crops 0.49 Crop land 0.53
Grazing Animals 0.14 Grazing land 0.27
Settlements & infrastructure0.08 Built-up area 0.08
Producing timber & fuelwood0.23 Forest 0.78
Absorbing excess CO2 1.14

Benefits of “Ecological Footprint thinking”:
• You can explain decision-makers the challenge: a complex, ecologically constrained world
• You can more easily communicate benefits of aggressive sustainability policies
• You can identify risks, new markets, and opportunities
How doesGlobal Footprint
Network operate?
• Non-profit research institute with 75+ partner organizations (academia, gov orgs, businesses, NGOs)
• Scientific forum for addressing the resource accounting question
• Standardization (www.footprintstandards.org)
• Ten-in-Ten goal (10 countries by 2015)

“London First”: What is the potential for reduction? Which technologies would be needed?
• Total London Ecological Footprint = 50 million gha• Possible to reduce London’s Ecological Footprint by
between 20 & 25 million global average hectares (gha)
