Presentation Transcript

  1. NRG 173: Carbon Footprints for Climate Action in Complex OrganizationsSpring Term 2011Class 3 of 20April 5, 2011 Kelly Hoell Good Company Eugene, OR

  2. overview • catch up from last week • activity: US energy (practice logical thinking) • review pop quiz • continue discussion of GHG inventory boundaries • LCA introduction • introduction to life-cycle thinking • LCA vs. GHG inventory – what is different? • components of an LCA • DEQ Home LCA • audience, purpose, goals, units • Homework for next time

  3. learning objectives • this session (Session 3) • Review GHG accounting framework and boundaries • Get our hands dirty with a real LCA. • Understand the concept of “functional unit” in the DEQ example (and beyond). • for next time (Sessions 4, 5, and 6) • More examples, more discussion of relevance. • Discuss the implications of “functional unit” selection on results for the examples to date. • Decide if the examples hold insights for other contexts. • Discuss the implications of the examples for personal, policy, and corporate decision making.

  4. activity: using logic, intuition, and knowledge please memorize this for test at 2 PM

  5. overview of US emissions • nomenclature

  6. activity: using logic, intuition, and knowledge please memorize this for test at 2 PM

  8. GHG accounting 101: Scopes 1, 2 and 3 Source: World Resources Institute

  9. conducting a GHG Inventory – an overview identify relevant protocols and tools set inventory boundaries collect data revisit inventory boundaries finish data collection calculate emissions write report share results with stakeholders develop climate action plan (Plan as much as reasonable. Be ready for loops.)

  10. typical emission sources • building-based energy use (utilities) • electricity • natural gas • other fuels (propane, fuel oil, coal, etc.) • refrigerants (“fugitive emissions”) • transportation • fuel use for business travel (air, car, bus, train) • fuel use for employee commute (single occupancy vehicle, carpool, mass transport) • distribution • embodied GHGs in supply chain • waste stream • land use (on a large scale)

  11. setting boundaries: think emissions sources… Source: World Resources Institute

  12. …and locations / facility types

  13. activity: business activity and emissions

  14. Activity: Good Company as an example

  15. trade-offs in setting boundaries

  16. activity: boundaries and data

  17. Life-cycle stages: Construction Use & maintenance Demolition Definition: assessment of a building’s environmental, social and economic impacts across every stage of the building life cycle life-cycle thinking life-cycle analysis

  18. Definition: assessment of a building’s environmental, social and economic impacts across every stage of the building life cycle Life-cycle stages: “Before” resource extraction raw material processing manufacturing distribution construction “During” inputs for use maintenance “After” disposal / landfill reuse recycling or composting life-cycle thinking life-cycle analysis

  19. life-cycle thinking example: building life-cycle

  20. life-cycle thinking example: building life-cycle BEFORE DURING AFTER

  21. GHG accounting 101: Scopes 1, 2 and 3 Source: World Resources Institute

  22. boundaries GHG accounting using life-cycle thinking? Source: World Resources Institute

  23. LCA process • goal definition and scoping • define and describe the product, process, or activity • establish context: ID boundaries and impacts to assess • inventory analysis • identify and quantify environmental releases for impact categories • impact assessment • assess effects of environmental releases • interpretation • evaluate results and make decisions with an understanding of sources of uncertainty and assumptions

  24. LCA process: Questions to ask Define the Goal(s) of the Project Determine What Type of Information Is Needed to Inform the Decision-Makers Determine the Required Specificity Determine How the Data Should Be Organized and the Results Displayed Define the Scope of the Study Determine the Ground Rules for Performing the Work

  25. DEQ Home LCA: goal definition and scoping • context?

  26. waste disposal and recovery 2009 Oregon Waste Generation = 4.6 million tons 20-30% of disposed waste is construction debris Source: OR DEQ, Jordan Palmeri slide

  27. DEQ Home LCA: goal definition and scoping • context? • purpose?

  28. initial study question Over the life of a home, how can you use fewer building materials or prevent waste? Source: OR DEQ, Jordan Palmeri slide

  29. DEQ Home LCA: goal definition and scoping • context? • purpose? • audience?

  30. DEQ Home LCA: goal definition and scoping • context? • purpose? • audience? • potential actions assessed?

  31. DEQ Home LCA: goal definition and scoping

  32. DEQ Home LCA: goal definition and scoping • context? • purpose? • audience? • potential actions assessed? • impacts assessed?

  33. impacts assessed • GHG emissions • non-renewable energy • costs • ecosystem quality • resource depletion • human health • carcinogens • non-carcinogen toxics • ozone depletion • acidification • eutrophication

  34. DEQ Home LCA: goal definition and scoping • context? • purpose? • audience? • potential actions assessed? • impacts assessed? • study boundaries?

  35. DEQ Home LCA: goal definition and scoping • context? • purpose? • audience? • potential actions assessed? • impacts assessed? • study boundaries? • functional unit?

  36. the functional unit: standard home • 2262 square feet • 3 bedrooms • 2 baths • 2 car garage • 2.5 occupants • “move-in ready” • includes original and replacement materials • vinyl windows • asphalt roof • gas furnace, no A/C • designed to 2008 Oregon energy code • energy use modeled for Portland, OR climate ***Lifetime = 70 years***

  37. homework • keep reading DEQ Home LCA • be prepared to discuss results • start your personal carbon footprint and climate action plan
