CAEP Description

 

The Committee on Aviation Environmental Protection (CAEP) is a technical committee of the ICAO Council established in 1983. CAEP assists the Council in formulating new policies and adopting new Standards and Recommended Practices (SARPs) related to aircraft noise and emissions, and more generally to aviation environmental impact.

 

CAEP undertakes specific studies, as requested by the Council. Its scope of activities encompasses noise, air quality and the basket of measures today considered for reducing international aviation CO2 emissions, including aircraft technology, operations improvement, market-based measures and alternative fuels. CAEP informs the Council’s and Assembly’s decision making by providing aviation environmental trends assessment including future air traffic projections and impact assessment of proposed policies and developments.

 

The Council reviews and adopts CAEP recommendations, including amendments to the SARPs, and in turn reports to the ICAO Assembly where the main policies on environmental protection are ultimately defined.

CAEP Terms of Reference

 

CAEP’s assessments and proposals are pursued taking into account: 

 

    • technical feasibility; 
    • environmental benefit;
    • economic reasonableness;
    • interdependencies of measures (for example, among others, measures taken to minimize noise and emissions);
    • developments in other fields; and
    • international and national programmes.

CAEP Activities

Working group 1 (WG1): Aircraft Noise Technical Issues
The main aim of WG1 is to keep international aircraft noise certification Standards (Annex 16, Volume I) up-to-date and effective, while ensuring that the certification procedures are as simple and inexpensive as possible.

 

Working group 2 (WG2): Airports and Operations
WG2 addresses aircraft noise and emissions issues linked to airports and operations.

 

Working group 3 (WG3):  Emissions Technical Issues
WG3 deals with aircraft performance and emission technical matters, including the updating of Annex 16 - Volume II and the development of the new aircraft CO2 Standard, Annex 16 – Volume III.

 

Modelling and Databases Group (MDG)

The MDG group carries out modelling efforts in support to the activities of the other CAEP groups and maintains various databases such as the movements, fleet, and population databases.

 

Forecasting and Economic Analysis Support Group (FESG)

The main role of the FESG is to develop and maintain the databases necessary to provide the framework for performing economic analysis and forecasting fleet growth. It provides support to the other working groups within CAEP and works with them on data issues that concern more than one working group.


Aviation Carbon Calculator Support Group (ACCS)
The ACCS group successfully develops and updates an impartial, transparent methodology for computing the CO2 emissions from passenger air travel.


Impacts and Science Group (ISG)
ISG informs the Secretariat and CAEP on scientific findings such as aircraft particulate matter impacts; climate impacts of aircraft emissions; and the implication to aviation of limiting the increase in global average temperature to less than 2ºC above pre-industrial levels.


Global Market Based Measure Technical Task Force (GMTF)
The GMTF is mandated to develop recommendations for the monitoring, reporting and verification (MRV system) of international aviation emissions and for the quality of offset remits for use in a global market-based measure for international aviation.


Alternative Fuels Task Force (AFTF)
The AFTF is mandated to assess the potential range of emission reductions from the use of alternative fuels in aviation up to 2050.
