  • 1. The ecological backpack: versatile indicator for sustainable consumption Satu Lähteenoja, Michael Lettenmeier, Marja Salo ConAccount conference 2008, Prague12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 2. This presentation is about• Confusion faced with different indicators• MIPS and ecological backpack• One case project on how it can be used• How to compare the indicators• Does backpack bring something new to the discussion?• Conclusions and further questions12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 3. Sustainable consumption – target for ecological cities?Sustainable consumption is understood as “the use of goods and services that respond to basic needs and bring a better quality of life, while minimizing the use of natural resources, toxic materials and emissions of waste and pollutants over the life cycle, so as not to jeopardize the needs of future generations” (The Norwegian Ministry of Environment 1994). You can’t manage what you can’t measure...12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague

  • 7. CO2-emissions vrs. Carbon footprint? Carbon footprint is nowadays used just to tell how many QuickTime™ ja TIFF (pakkaamaton) pakkauksen purkuohjelma tonnes of CO2 is tarvitaan elokuvan katselemiseen. consumed => it’s not telling about area Source: footprintnetwork.org, Yahoo green12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 8. Water footprint? QuickTime™ ja TIFF (pakkaamaton) pakkauksen purkuohjelma tarvitaan elokuvan katselemiseen.The water footprint is an indicator of water use that looks at both direct and indirect water use of a consumer or producer. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. Water use is measured in terms of water volumes consumed (evaporated) and/or polluted per unit of time.

  • 9. Why is it called footprint?Area of water needed? Can not be measured as an area... Source:waterfootprint.org12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 10. MIPS (Material Input Per Service) material input = life-cycle-wide resource consumption service unit = total benefit obtained12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 11. Ecological backpack= resource consumption (non-renewable and renewable resources and erosion) of a commodity over its whole life cycle (g, kg, tonnes) 12.09.08 ConAccount Lähteenoja, Lettenmeier, Salo Conference 2008, Prague
  • 12. Not just one backpack Abiotic resource backpack TMR Biotic resource backpack Soil backpack Water backpack Air backpack CO2 backpack?12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague

  • 14. Case: FIN-MIPS Household research project 2006-20081. MIPS studies covering different aspects • pre-study on existing data • 6 master’s theses2. Application of the MIPS data to households • 27 different households monitoring their consumption • piloting and assessing the use(fulness) of MIPS3. Illustration and conclusions • suggestions and conclusions: How to reach factor-targets? 12.09.08 ConAccount Lähteenoja, Lettenmeier, Salo Conference 2008, Prague

  • 19. Conclusions - what do different indicators tell?• CO2 => energy• Ecological footprint => energy and agriculture• Water consumption => agriculture• Abiotic resource backpack => infrastructure and non-renewable materials12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 20. Conclusions• MIPS is rough but easy, still less used and perhaps underestimated• With one method, it is possible to study different aspects of resource consumption by different backpacks=> Good experiences from Finland12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 21. Conclusions• Footprint is clearly understandable, when used to describe area needed• However, it lacks with taking infrastructure into account• It confuses when the term footprint is used to tell about CO2 emissions (kilogramms) or water (cubic meters / tonnes)12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
  • 22. We need many indicators, but...• Let’s not spoil the great success of footprint by mixing it with everything (e.g. ”mobility footprint”)• Instead, we could talk e.g. about CO2 backpack and water backpack to indicate the amout of these resources used in kilograms, when not indicating it to the needed land.12.09.08 ConAccount Lähteenoja, Lettenmeier, SaloConference 2008, Prague
