  1. MAKING SUSTAINABILITY WORK Estimating Embodied Emissions in the Supply Chainmethods, results and lessons learned Presented by Kelly Hoell, Associate and Tracy Sagal, Associate Good Company 65 Centennial Loop, Suite B Eugene, Oregon 97401 www.goodcompany.com phone 541.341.4663 fax 541.341.6412

  2. Overview • supply chain analysis: approach & tool • What do the results mean? How are they different from other emissions sources? • results and lessons learned • Leslie Kochan: Oregon DEQ • Discussion

  3. Overview

  4. Overview

  5. approach: converting dollars to GHG Emissions • $ = expenditure • CO2e/$ = “carbon intensity” of expenditure • CO2e = final estimate of total emissions in expenditure

  6. supply chain carbon: EIOLCA • powerful web-based, public-domain tool • carbon intensity database for different industries • use it to estimate supply chain GHG emissions • translates economic activity into GHG emissions • easy to use (especially compared to the alternative) • free to use • website: http://www.eiolca.net

  7. supply chain carbon: EIOLCA • Economic Input-Output (EIO) = • model of the US economy • includes 428 economic sectors • based on 2002 data • Lifecycle Assessment (LCA) = • details from the academic literature on GHG emissions • looks at embodied emissions up to the point of purchase

  8. Results: City of Hillsboro

  9. Results: City of Hillsboro

  10. Results: what do they mean? • Estimate • Rough, sense of scale, high level • Unlike other emissions sources • results can vary widely year-to-year • annual analysis won’t show “progress” towards goals • Supply chain is a big deal • often overlooked • deserves attention • Guidance on where to focus low-carbon purchasing efforts

  11. Results: 11 Oregon public entities
