27 April 2007

2. Operation Pre February 2007 CCA10 submission
Submission of CCA23 Annex 1 data
Further guidance on CHP
CCA10 submission
Calculation at facility level
Calculation at sector level

3. Sector correction for trading and double counting
R146 is ‘=SUMPRODUCT(R13:R133,N13:N133)’

4. Results No of TUs involved 139+ No of sectors involved 23
Net amount of EU allowances (EUA) in corrections
3,634,000 causing a tightening in CCA targets
Total EUA resulting in an easing of targets
198,000
Total EU resulting in a tightening of targets
3,832,000
Number of TUs cancelling allowances to avoid a double counting correction 4
Allowances cancelled
46,000

5. Results - TUs and size of target changes

6. Results CO2 by percentage change

7. Results – pass/ fail by TU indication
To be advised

8. Conclusions
The CCA23 approach provided an accurate method of correcting for double counting
With further guidance, if the CCA23 method is used for future milestones, the process will be much smoother.
