1. Introduction to Domestic Emissions Trading Warren Bell Associate, IIISD Kyoto Mechanisms Seminar for the Manitoba Business Sector March 14, 2003

2. Emission trading basics Kinds of emission trading Key elements of a trading system Targets for large industrial emitters The role of offsets Outline

3. Emission Trading: An alternative to traditional command and control regulation in many environmental and resource areas: –air emissions, fishing quota, lead in gasoline Combines a regulatory approach with the flexibility and innovation of private markets Provides a common price signal to emitters – the market then determines where emissions occur, where abatement occurs

4. How Emission Trading Cuts Costs Objective: Reducing emissions by 2 tonnes Plant APlant B Plant A Plant B $100/tonne $225/tonne Each plant reduces 1 tonne total cost: $325 Plant B “hires” Plant A Plant A reduces 2 tonnes Total cost: $200 No tradingTrading $50 $100 $150 $200 $250 $300 Cost per tonne

5. Advantages of Emission Trading Emitters are given flexibility and control –Firms choose to emit/abate, not bureaucrats Rewards innovation and investment in new technology –an incentive to go beyond minimum requirements Common price signal ensures that reductions take place where they are least costly –achieves environmental goals at least cost The overall cap on emissions ensures environmental objective is achieved

6. Disadvantages of Emission Trading Still requires monitoring, reporting, verification and compliance infrastructure - like traditional regulation May result in increased local concentrations of emissions Price is uncertain – determined by market Relies on a price signal – some markets may be less efficient Allocation of target/allowances is highly contentious

7. Kinds of Emission Trading Trading within a capped or regulated sector –“Closed market” trading of allowances or permits –“Cap and trade” –Examples: International emission trading between Annex B countries, U.S. Acid Rain program trading Trading outside a capped or regulated sector –“Open market” trading of offsets or credits for project- based reductions or removals –Credits are used for compliance by capped entities –Trading is one-way – into the capped sector –Examples: Clean Development Mechanism, Ontario emission trading system, Alberta offset requirement

8. Key Elements Required A limit on emissions – less than BAU Participants must have different costs for emission reduction Monitoring and reporting requirements Trading rules – banking, offsets Consequences for non-compliance

9. Emission Limits or Targets Absolute limits –X tonnes/year (Canada’s Kyoto target) Intensity limits –X tonnes/GW.h –Y tonnes/tonne market pulp –Z tonnes/$GDP Canada is proposing to set intensity targets for large industrial emitters

10. Intensity Targets Advantages: –Preserves incentive for efficiency while not penalizing growth – addresses some competitiveness concerns –Addresses problems related to new entrants, shutdowns –Does not penalize firms who take early action (but a problem at sector level) Challenges: –Measuring output –Basis for defining target – technology/cost analyses? Across the board cuts? –Limited incentive for structural change –No overall limit on emissions – unless targets adjusted

11. Intensity Targets for Large Industrial Emitters Key Issues for large emitters: –Achievability of overall target –Risk from growth –Equity across sectors Uniform 15% off 2010 BAU intensity may penalize sectors that took early action –Huge diversity within some sectors E.g., electricity –Need to maintain incentives for lower emission technologies

12. Offsets Allowing credits or offsets for project-based emission reductions/removals would: –Expand participation in the trading system –Promote investment in emission reductions outside the capped LIE sector –Keep investment dollars in Canada –Increase the number of compliance options, and potentially reduce costs –Could provide environmental and other co-benefits Potential offsets - landfill gas capture and flaring, agriculture and forestry reductions & removals

13. Possible Offset System Credits would be earned for voluntary reductions below an emissions baseline Possible criteria for eligible reductions: –real (beyond business as usual), measurable, verifiable, surplus (beyond what is required), additional/incremental –real project experience from Canadian pilots – Greenhouse Gas Emission Reduction Trading (GERT) pilot and Pilot Emission Reduction and Trading (PERT) project Credits would be certified by an accredited body Credits could be used for compliance with targets

14. Key Questions For those who may face emission limits: –How will targets be set? –What kind of flexible compliance options will there be? For other sources: –What will the rules be for offsets?
