2. What I’m Going to Tell You
 Summarize Alberta GHG Regulatory and
Offset System
 What We Have Do to Get More Offset
Credits
 Our Current Status

3. GHG - Yada, Yada, Yada

4. Alberta GHG Regulatory
System
 Climate Change and Emissions
Management Act
 Specified Gas Emitters Regulation.
 Emitters >100,000 tonnes CO2-
e/yr) required to:
 Reduce emissions intensity by 12%;
 Pay $15/tonne into Alberta based
technology fund; or
 Purchase offset emission
credits from Alberta based
operations.

5. Alberta Offset System
 GHG offset protocols
– developed for various offset activities/projects
 ECF emission and project statements
– used to draft Alberta Composting Protocol
 Alberta Composting Protocol
– approved Sep 2007

= Emission Reduction

Project Condition

11. Calculations Simplified
 Default approach claim
– CH4 generation potential avoided in the year
the material is diverted from landfilling.
 Baseline and composting conditions,
– quantities for CH4 and N2O are calculated.
– CO2 emissions considered biogenic
 therefore not included

12. So What Do We Have To DO
To Get More Offset Credits

AERC
C & D Recycling
Landfill Closed

14. Edmonton Compost
Facility

15. Cure Site

16. Measure & Record
 Hard Data
 Materials
– all feedstocks to composting
– all residuals to landfill
– Other materials diverted
(e.g. recycled)
 Energy Consumed
– equipment fuel
– electricity

17. Manage Electrical Energy
Consumption

18. Reduce Fuel Use

19. Compost More

20. More Composting

21. And More Composting

22. Reduce Residuals

23. Recover More From
Residuals

26. Market Realities
 Price Cap $15/tonne
 $11-$13/tonne CO2-e in Alberta system
 Value based on
– quality of data management
– discrepancies/leakages.
 More buyers than available offsets
 Purchaser Interest
– Quantities of > 20,000 tonnes CO2-e

27. City of Edmonton Status
 2007 and 2008 offsets from ECF
– quantified in early 2009 and verified.
 Registration and serialization of offsets
on Alberta Registry
– completed in early June.
 Sale to purchaser negotiated,
– long term future sales contract signed.
 Delivery of 2009 ECF offsets to
purchaser
– March 2010.
