Comparing Corporate Performance | Craig Mackenzie

  1. 1. Comparing corporate performance on climate change – what metrics? Dr. Craig Mackenzie Director, Carbon Benchmarking Project University of Edinburgh Business School
  2. 2. Why benchmark corporate climate change performance? <ul><li>“ The energy efficiency of individuals and firms often varies widely within the same market…methodologies for identifying best practice, for example through benchmarking… have the potential to support wider policies on mitigation.” </li></ul><ul><li>Stern Report. p.388 </li></ul>
  3. 3. The scope for low cost reductions Source: Vattenfal
  4. 4. Overcoming the barriers <ul><li>Lack of strategic significance </li></ul><ul><li>Organisational inertia </li></ul>
  5. 5. Supermarkets benchmark
  6. 6. Breakdown of the Tesco footprint Add note on fridge energy? Refrigeration Tesco CSR Report 2007
  7. 7. Direct CO2e emissions No Data
  8. 8. Relative carbon intensity? NB: this slide does not give an accurate comparison of performance No Data
  9. 9. Data issues NB: this slide does not give an accurate comparison of performance Data estimated Data incomplete No Data Few use GHG protocol
  10. 10. Additionality questions NB: this slide does not give an accurate comparison of performance Use of biodiesel Green tariff electricity Green tariff electricity No Data
  11. 11. Business comparability issues NB: this slide does not give an accurate comparison of performance Food processing business Food non-food split Food non-food split No Data
  12. 12. Meaningful comparison? NB: this slide does not give an accurate comparison of performance Food processing business Food non-food split Food- non-food split Food non-food split Use of biodiesel Green tariff electricity Green tariff electricity Data estimated Data incomplete No Data
  13. 13. An alternative strategy Add note on fridge energy? Refrigeration Tesco CSR Report 2007 % f-gas leakage pa KWh/linear meter of refrigeration Diesel litres/pallet delivered Average store energy rating % electricity from renewables weighted for additionality
  14. 14. Advantages of granular metrics <ul><li>Allows meaningful performance comparison </li></ul><ul><li>Identifies specific strengths and weaknesses </li></ul><ul><li>Enables identification of causes for differing performance </li></ul><ul><li>Potential to accelerate uptake of best practice </li></ul>
  15. 15. Wider implications Benchmarking needs: <ul><li>Better data quality </li></ul><ul><li>Sharper standards </li></ul><ul><li>Segmental carbon reporting </li></ul><ul><li>Identification and reporting on normalisation factors </li></ul><ul><li>Avoiding carbon reductionism </li></ul><ul><li>Activity-specific metrics </li></ul><ul><li>Activity/sector-specific reporting standards </li></ul><ul><li>Collaborative sector/activity projects to define the above </li></ul>
