AdvancingSustainable Production with

the Ecological Footprint

Yes, Footprint is becoming more popular…

an

…and it provides a measurement method to comparehuman demandagainst biosphere’s regenerative capacity

Footprint Benefits:

• You can explain the challenge: a complex, ecologically constrained world

• You can communicate benefits of sustainable manufacturing

• You can identify risks, new markets, and opportunities for sustainable manufacturing

How much “nature” is available?

With 6.3 billion people (2003)Current global average availability of bioproductive land + sea area

= 1.8 global hectares/person

What Does the Footprint Measure?

• Footprint: How much of the biosphere’s regenerative capacity is used by human activities?

• Biocapacity: How much of the biosphere is available within a region?

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 & infrastructure 0.08 Built-up area 0.08

Producing timber & fuelwood 0.23 Forest 0.78

Absorbing excess CO2 1.14

Harvesting Fish 0.15 Fishing Grounds 0.14

Total Global Demand 2.2 Total Global Supply 1.8

“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)
