  1. Calculating the environmental footprint of a university - The case for NTNU Hogne Nersund Larsena*, Christian Sollia, Johan Pettersena aMiSAAS, Innherredsveien 7b, NO-7014 Trondheim, Norway * Corresponding author, e-mail: hogne@misa.no

  2. Outline • Introduction - About MiSA - Motivation of work - The Carbon Footprint • Presentation of work - The Carbon Footprint of NTNU - The Environmental Footprint of a renovation project • Conclusion - General findings - NTNU findings

  3. MiSA – Environmental Systems Analysis - We offer Life Cycle Assessment and Environmental Footprinting of products and organizations - A spin off company of the Industrial Ecology Programme at NTNU. Had offices for 2 years at the Innovation Center at NTNU - Established in 2007, 9 employees in 2012 (5 PhD). Moved to new offices at Solsiden in Trondheim

  4. Relevant research areas • Two main developments within environmental footprinting and system analysis: • Life Cycle Assessment (LCA) of products, such as: • - Agriculture • - High speed rail • - Drilling operations • - Wind power • - Carbon Footprint inventories of entities: • - Municipalities • - Counties • - Other public entities • - Companies and organizations

  5. Motivation for Supply Chain Management (SCM) and Carbon Footprinting (CF) A large fraction of life cycle emissions occur upstream in the supply chain New set of possibilities to reduce the GHG emissions resulting from an entity or product The law on public procurement

  6. Direct emissionsenergyindirectemissions • A large fraction of life cycle emissions occur upstream in the supply chain - Scope 1, 2 and 3 contribution of all Norwegian sectors - Indirect, Scope 3, contributions dominates - Direct, Scope 1, GHG emissions dominate only; energy, agriculture, waste and transport sectors - Supply Chain Management and inclusion of Scope 3 emissions are hence important!

  7. IntroducingtheCarbonFootprint • The life-cycle GHG emissions caused by the production of goods and services consumed by a geographical defined population or activity, independent of whether the GHG emissions occur inside or outside the geographical borders of the population or activity of interest

  8. How do we calculate the Carbon Footprint WRI and WBCSD. 2004. The Greenhouse Gas Protocol - A Corporate Accounting and Reporting Standard: World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD). Total Carbon Footprint CO2-equivalents (CO2e): {CO2 N2O CH4 CO SF6 HCFs PFCs } Scope 1 Direct emissions Scope 2 The purchase of energy Scope 3 Indirect emissions Combustion of fossil fuels Supplies Food Energy Pettersen, J., H.N.

  13. The carbonfootprintof NTNU Trondhjem Tekniske Høiskole med elven aug. 1911

  14. Motivation: A complete Carbon Footprint inventory aimed to identify target areas

  15. Key elements: • Klimakost model • - Environmentally extended input-output model • - Norwegian domestic tech., EU27 import tech. • Uses financial numbers on purchases as main source of data • Identifies all purchases, and also the buyer

  16. My seem complex… and it is  The Carbon Footprint of Norwegian household consumption (7 sectors + import and direct GHG emissions, imagine 116!) Annualaccounts NTNU Departments EEIO system A (trade data of 116 sectors) Y CF Purchases F (emission data from 116 sectors) More than 15 000 entrys…

  17. Some key data on the NTNU study

  18. Overall results, carbon footprint

  19. Detailed results, carbon footprint of consumables

  20. The carbon footprint per faculty

  21. Normalized carbon footprint per faculty energy transport buildingsconsumablesequipment services

  22. Comparing normalized results

  23. LCA ofbuildingrenovation

  24. NTNU Grønnbygget • A renovation project • FDV-documents provided all data on components added in the renovation process • Data on building waste also available

  29. 29 Conclusions, general The life cycle perspective (footprint) is important because: - a large fractions of the emissions are located in the upstream supply chain! - Reducing emissions locally has no use if global emissions stays the same! - There is a great potential in using the purchasing power in green procurement

  30. 30 Conclusions, NTNU Main conclusions of the NTNU study: - basically no direct GHG emissions - significant energy related carbon footprint - travels are important - Significant part of the carbon footprint embodied in consumables and equipment
