Good Company

Eugene, OR


overview Organizations

  • 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


learning objectives Organizations

  • 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.

conducting a GHG Inventory – an overview Organizations

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.)


typical emission sources Organizations

  • 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)


setting boundaries: think emissions sources… Organizations

Life cycle analysis

Life-cycle stages: Organizations

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


Life cycle analysis1

Definition: Organizations

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

LCA process Organizations

  • 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


LCA process: Questions to ask Organizations

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



waste disposal and recovery Organizations

2009 Oregon Waste Generation = 4.6 million tons

20-30% of disposed waste is construction debris

***Lifetime = 70 years***


homework Organizations

  • keep reading DEQ Home LCA

    • be prepared to discuss results

    • start your personal carbon footprint and climate action plan
