Civil Aviation Organization (ICAO)
AGENDA 21 CHAPTERS AND PROGRAMME AREAS OF PARTICULAR FOCUS OR INTEREST:
See check list in annex.
BRIEF DESCRIPTIONS OF AND LINKS TO INFORMATION ACTIVITIES:
Collection, Observation, Monitoring
Information is collected
by questionnaire, or by correspondence, from States' aviation administrations,
airlines, aircraft and engine manufacturers, and scientific research
The following three types of data contribute to ICAO's work on aircraft
engine emissions and are of potential relevance to Chapter 9 of Agenda
- Under Article 67 of the
Convention on International Civil Aviation, each State undertakes
that its international airlines shall file traffic reports, cost statistics
and financial statements with ICAO. For details, see Manual
on the ICAO Statistics Programme (DOC 9060-AT/723/4).
- Information collected
from aircraft engine manufacturers on the emissions characteristics
of their engines during the landing and take-off cycle is assembled
in the ICAO Exhaust Emissions Data Bank.
- On behalf of ICAO's Committee
on Aviation Environmental Protection, NASA maintains a world-wide
database on "Research on Atmospheric Effects of Aviation". The data
for this database is collected by questionnaire from governments,
Methodologies, Quality Control, Harmonization
Standardization of aviation statistics world-wide under the ICAO Statistics
Programme. ICAO holds regular statistical workshops to ensure quality
control in support of the ICAO Statistics Programme.
Harmonization is provided for under the ICAO Statistics Programme.
ICAO has developed various forecasting methodologies relevant to civil
aviation (for example, traffic forecasts and fleet forecasts).
While it is difficult to give precise cross-references to Agenda 21,
ICAO's analytical work in support of policy-making on aircraft engine
emissions is likely to be relevant in connection with Chapter 9 (Protection
of the Atmosphere) Programme Areas: B2 Promoting Sustainable Development
(Transportation)- particularly paragraph 9.15 (c); C Preventing Stratospheric
Ozone Depletion; and D Transboundary Atmospheric Pollution - particularly
paragraphs 9.28 (a) and (d). ICAO is at present seeking accurate reliable
assessment of whether - and, if so, to what extent - aircraft engine
emissions contribute to climate change and to stratospheric ozone depletion.
When the impact of aircraft engine emissions is better defined, ICAO
will seek appropriate solutions.
In September 1996, the IPCC agreed to undertake a Special Report on
Aviation and the Global Atmosphere,
in collaboration with the Ozone Scientific Assessment Panel under the
Montreal Protocol and with ICAO involvement.
Techniques used are assessment of relevant technology; development of
emission inventories; cost-benefit analysis of mitigating operations.
Expert Systems/Decision-support systems
Data collected through ICAO's Statistics Programme are published in
hardcopy form and are also available on tape or diskette. The first
edition of the ICAO's Exhaust Emissions Data Bank was published in 1995
(ICAO Doc 9646-AN/943).
Most of the information emerging from ICAO's work on aircraft engine
emissions is primarily being developed for use by States within the
context of ICAO's decision-making processes. Such information would
not normally be disseminated outside ICAO, but, if appropriate, could
be made available to other UN bodies.
Information is made available in a form appropriate for use by ICAO's
Network Development and Support
In connection with ICAO's Statistics Programme, ICAO holds statistical
workshops aimed at helping States to fulfil their statistical reporting
obligations to ICAO.
