1. ICAO CO2 Reporting and Analysis System (ICORAS)
Air Transport Bureau

2. ICORAS ICAO CO2 Reporting and Analysis System ICORAS
An Air Transport Bureau project involving two strategic objectives:
D- Economic Development of Air Transport
E- Environmental Protection

3. Background of ICORAS project Assembly Resolutions of A37
Aspirational goal of 2% fuel efficiency gains per year
Report CO2 emissions from international aviation to United Nation Framework Convention on Climate Change (UNFCCC)
Measure progress on annual fuel efficiency
Measure progress toward keeping net CO2 emissions at same level from 2020
A37-20 – Appendix B:
Need for the Organization to collect data from State on annual aviation fuel consumption

4. Air Transport Committee
ICAO Statistics Programme foundations
Assembly Resolutions (A37-20, App. B):
Whereas the development of ICAO’s validation and storage Integrated Statistical Database provides Contracting States and other users with an efficient online system for the retrieval of statistical data;
Requests the Council, calling on national experts in the relevant disciplines as required, to examine on a regular basis the statistical data collected by ICAO and etc…

5. New Form M
New Form M: unique source of performed traffic and related fuel consumption data
The State letter EC 7/1.6-12/69 has been sent in December 2012 to request States’ support in urging their carriers to submit 2010 and 2011 data on Air Transport Reporting Form M

6. Reporting and Analysis System
ICOARS Project
Member States
Though the ICAO Statistics Programme:
Form M: New Form on performed fuel consumption by commercial air carriers
clarification, correction, reminders
collection, verification
Integration of the reported performed fuel consumption into a database of modelled fuel consumption developed by ICAO
Preliminary results to be discussed during A38
Performed fuel consumption received by ICAO
covers 50% of the world international traffic*
*: expressed in Revenue Tonne-Kilometers on scheduled services

7. Main data sources
ICAO Statistics Programme (Air Transport Reporting Forms):
Fuel consumption: Form M
Traffic:
Form A: Commercial air carrier traffic by carrier
Form A-S: Total traffic of all commercial air carriers of a State
Form B: On-Flight Origin and Destination
Form C: Traffic by Flight Stage
Annual Report of the Council – Statistical tables
Revenue Cost Analysis (RCA) database

8. ICORAS Benefits
Actual performed fuel consumption reported by Member States (50% of world international scheduled traffic)
Reported fuel consumption enables benchmark and model accuracy improvements aligning fuel burn estimates with actual fuel consumed data.
Sophisticated validation routines of ICORAS improves accuracy and consistency of results.
Facilitates reporting of fuel burn and associated metric harmonized with Annual Report data.
Facilitates policy making activities of States

9. Challenges linked to different definitions of International Aviation
For example, Ninth Freedom Right or “stand alone” cabotage is:
Ninth Freedom Right: Operate only in a foreign State
Source: Doc Manual on the Regulation of International Air Transport
It represents:
International traffic for ICAO
Domestic traffic for UNFCCC

10. Challenges linked to the different Reporting Systems
ICAO Member States report fuel consumption of their own air carriers and not by State of Departure
To properly report to UNFCC, the fuel consumption by State of Departure of the Aircraft needs to be derived

11. Next steps
1) Encourage States to report in a timely and accurate manner to the ICAO Statistics Programme
2) Consider the best approach to integrate
non-scheduled traffic and
business jet data
into the ICORAS system.
