Der ökologische Fussabdruck: Vom Labor der Wissenschaft zu weltweiten Anwendungen Dr. Mathis Wackernagel Plattform Footprint – 10. Jänner 2008 Ecological Creditors and Ecological Debtors Metabolism like a cow Bioproductive Segments Bioproductive segments 22% 67% LowProductivity Ocean 4% Biologically Productive Ocean 18% Biologically Productive Land 11% Deserts, Ice Caps and Barren Land 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 absorption Fibres Die Globale ökologische Bilanz (in global hectares/person, 2003 data) Human Demand (Ecological Footprint) Ecological Supply (Biocapacity) Demand Footprint Areas for: Growing Crops 0.49 Grazing Animals 0.14 Settlements & infrastructure 0.08 Producing timber & fuelwood 0.23 By Absorbing excess CO2 1.14 25% Harvesting Fish 0.15 Total Global Demand 2.2 Exceeds Supply > Biocapacity Areas: Crop land 0.53 Grazing land 0.27 Built-up area 0.08 Forest 0.78 Fishing Grounds 0.14 Total Global Supply 1.8 Data for 2003 Eco-Footprint Biocapacity [global ha/cap] [global ha/cap] Canada China Germany Italy Japan Russia United Arab Emirates US 7.6 1.6 4.5 4.2 4.4 4.4 11.9 9.6 14.5 0.8 1.7 1.0 0.7 6.9 0.8 4.7 WORLD 2.2 1.8 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 does Global 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) Ten-in-Ten Candidates Six Pioneer Countries Switzerland Japan United Arab Emirates Belgium Ecuador France Looking into the Future Global Context for the Coming Decades UN’s most moderate scenario Is there enough natural capital to liquidate for a Moderate Business-as-Usual Path? Slow Things First Map Lifespan of People, Assets and Infrastructure against Time Spans of Biosphere Billion 2003 global hectares 24 Long-term waste 12 Calgary “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) London Remade with WSP Environmental, Global Footprint Network Building Momentum: The Footprint of an Australian General Retailer Footprint (gha) Bigger Footprint for Solution Providers E.g.: Waste Management as Investment potential actual Footprint for Waste Management Recuperated Footprint from Waste (INVESTMENT) (RETURN) HDI Ecological Footprint (gha per person) Niger's Footprint 4.0 3.5 Niger's Biocapacity 3.0 gha per capita World Biocapacity 2.5 2.0 1.5 1.0 0.5 0.0 1960 1965 1970 1975 1980 1985 1990 Niger in the face of climate change 1995 2000 Africa's Footprint 4.0 3.5 Africa's Biocapacity 3.0 gha per capita World Biocapacity 2.5 2.0 1.5 1.0 0.5 0.0 1960 1965 1970 1975 1980 1985 1990 Africa If you were their Executive Council? 1995 2000 x x RESOURCE INTENSITY CONSUMPTION POPULATION GAP BETWEEN BIOLOGICAL DEMAND AND SUPPLY BIOPRODUCTIVITY AREA x = ECOLOGICAL FOOTPRINT (DEMAND) = BIOCAPACITY (SUPPLY) Winning together!
