1. An IIR- Experiences from the UK Chris Dore AEA Technology/NETCEN 5th Joint UNECE Task Force & EIONET Meeting 19-20th October 2004

2. Introduction An IIR- UK Experiences 1. A “Detailed” IIR 2. A “Simpler” IIR 3. Discussion Points

3. 1. “Detailed” IIR An IIR- UK Experiences Annual Reports from the UK Inventory –GHG NIR –UK Inventory Report (including full methodology)

4. 1. “Detailed” IIR An NIR- UK Experiences The UK GHG NIR Report: –Has four Executive Summaries –Ten Annexes –and is 364 pages UK Inventory methodology is similarly large So, compiling a detailed IIR is time consuming! –The “detailed” UN/ECE IIR takes several days of formatting etc. –Format is prescriptive –Is this level of detail required?

5. 2. Simpler IIR An IIR- UK Experiences Proposals outlined by TFEI are helpful –Explanations of notation keys & “other” in templates –Fuel statistics in templates Much much easier! A “simple” report does typically takes less than two days Key source analysis to identify major sources But no detail on methodologies ? Lt.Col. Haddon OBE: “You will continue to score low marks unless you show your working!”

6. 3. Discussion Points An IIR- UK Experiences What is the purpose of this report? To support data submission –Key source analysis only (consider required detail) or To report methodology –Need for completeness (include Efs and activity data) 1. The guidelines should be taken as a minimum requirement –And countries should be encouraged to report more information

7. 3. Discussion Points An IIR- UK Experiences 2. Suggest including methodology information … and how to keep it simple! Propose a minimum of a “methodology summary table” with text: –by source and by pollutant –indicating simple information on activity data and EF’s –Could be in the report, or template Important sources should be accompanied by text –Also text explaining temporal step changes 3. Can IIR include hyperlinks instead of text? 4. Log ideas for improvement.

8. Thank-you!
