  1. 1. Marginal abatement cost curves: a call for cautionFabian KesickiUN Climate Change Conference (SB 34) in Bonn, 7th June 2011<br />
  2. 2. This presentation is based on the report ‘Marginal Abatement Cost Curves: a Call for Caution’ written by Ekins, P., Kesicki, F. and A. Smith<br />A research article of the same name is forthcoming in Climate Policy.<br />2<br />

  8. 8. POLICY USE OF MAC CURVE<br /><ul><li>Many areas:
  9. 9. Electricity saving
  10. 10. Air pollution
  11. 11. Waste reduction
  12. 12. Water availability
  13. 13. Energy-related emissions reduction
  14. 14. REDD
  15. 15. Many countries:
  16. 16. USA, EU, UK, France, Mexico, China
  17. 17. REDD: Congo for example</li></ul>5<br />
  18. 18. PROBLEMS WITH CURRENT MAC CURVES<br /><ul><li>Unclear assumptions
  19. 19. Cost definition
  20. 20. Implementation barriers
  21. 21. Discounting
  22. 22. Intertemporal issues
  23. 23. Interactions / baseline emissions
  24. 24. Behavioural aspects
  25. 25. Ancillary benefits/costs
  26. 26. Handling uncertainty
  27. 27. Financial focus</li></ul>6<br />

  30. 30. MAC CURVES AND REDD<br />Nabuurs et al. 2007<br />Kindermann et al. 2008<br />Eliasch 2008<br />Grieg-Gran 2008<br />Nauclér and Enkvist 2009<br />Kindermann et al. 2008<br />Stern 2007<br />Holdren 2007<br />(Brazil only)<br />Blaser and Robledo 2007<br />
  31. 31. MAC CURVES AND REDD<br /><ul><li>Uncertainty concerning baseline emissions
  32. 32. Focus on opportunity cost without considering administration, implementation, monitoring costs
  33. 33. Price discrimination
  34. 34. Potential leakage
  35. 35. Interactions with demand for bioenergy, timber industry</li></ul>10<br />
  36. 36. CONCLUSIONS<br /><ul><li>MAC curves: simple and useful illustration tool; first, rough guide to abatement costs and potentials at a specific point in time
  37. 37. Previously outlined caveats may have been overlooked in the past
  38. 38. MAC curves should be applied very carefully in the REDD debate</li></ul>11<br />
