  1. Third Annual International Sustainable Development Conference Sustainability – Creating the Culture 15-16 November 2006, Perth, Scotland Triple-Bottom-Line Accounting of Social, Economic and Environmental Indicators A New Life-Cycle Software Tool for UK businesses Dr Thomas Wiedmann Prof Manfred Lenzen

  2. SD Reporting & TBL Accounting

  3. “Corporate sustainability reports and sustainability ratings are increasingly used as key information for investment and lending decisions.” “There is a growing awareness that shareholders’ value is enhanced by increased corporate social and environmental responsibility.” World Business Council for Sustainable Development (2002)

  4. Challenges remain… • “There is little comparability …” • “A key challenge remains reporting on the links between sustainability and the bottom line.” • “Business will increasingly be expected to report … on supplier- and consumer-related impacts of activities, products and services.” World Business Council for Sustainable Development (2002)

  5. Trucost & Defra (May 2006)

  6. Reporting on direct and indirect KPIs • “The Government expects businesses to report on their significant environmental impacts whether they are direct or indirect.” • “Businesses are likely to derive benefit from positively influencing their indirect environmental impacts.” Trucost & Defra (May 2006)

  7. Indirect (environmental) impacts Supply Chain Impacts (upstream) Direct Company Impacts (on-site) Downstream Impacts Energy Water Raw materials Logistics Boiler emissions Car fleet emissions Manufacturing emissions Landfill waste Recycling rate Products in use Product disposal Trucost & Defra (May 2006)

  8. The problem of quantification • “… there is still a lack of quantification in most reporting. … the majority of reports lack depth, rigour or quantification.” • “Most business will have supply chain impacts that they should understand and consider reporting. There is no single, quantifiable measure that companies can use as a Key Performance Indicator for the effect of their upstream supply chain on the environment.” Trucost & Defra (May 2006)

  9. SD Reporting Principles • Principle 1: quantitative • Principle 2: relevant & reliable • Principle 3: comparable • Principle 4: complete

  10. TBL Accounting without boundaries

  11. Where to draw the boundary?

  12. e.g. total emissions (direct plus indirect) e.g. direct (on-site) emissions e.g. purchases of a company

  13. BottomLine3 A new TBL software tool

  14. Two data inputs • Financial accounts • On-site impacts

  15. Outputs • > 100 TBL indicators • Quantification of total (direct and indirect) impacts • Sector benchmarking • Structural path analysis • Production layer analysis

  16. Main TBL indicators

  17. Benchmark spider diagram (TBL)

  18. Production Layer Decomposition Energy demand (GJ) Company Suppliers of Suppliers Suppliers

  19. Structural Path Analysis

  20. Structural path analysis (particulate matter)
