A36-12 Introduced by the United States “Consider a mandate” for halon replacement 3 3

Background 2009 – Decision XXI/7 Parties’ continued support for mandatory dates in agreed upon applications; Request TEAP and HTOC to continue to engage ICAO 2009 - Stakeholders meeting ICAO, Industry, UNEP Ozone Secretariat and HTOC Agree to support halon replacement timeframe Move from “consider” to “establish” a mandate Contaminated halons in Europe 2010 – ICAO General Assembly Res.

Progress 16 November 2010, ICAO Air Navigation Commission (ANC) considered proposals to amend Annexes 6 and 8 of the Chicago Convention Annex 6 – Operation of Aircraft: 1. Intl Commercial Air Transport Aeroplanes; 2. Intl General Aviation, Aeroplanes; and 3. Intl Operations - Helicopters Annex 8 — Airworthiness of Aircraft Establish requirements and timeframes for halon alternative fire extinguishing agents Supported alternatives with least environmental impact (e.g., Climate) while meeting fire protection performance ANC agreed to send proposals to ICAO Member States and appropriate international organisations for consultations 5 5 5

Progress Russian Federation concerned specified timeframes would have a large financial impact on the industry ANB Secretariat & HTOC co-chair met with Russian ICAO Delegate Provided further clarifications Would now agree with proposal Russian Federation HTOC co-chair would offer to provide assistance within the Russian Federation ICAO ANC met again on 2 May 2011 Forwarded proposals to ICAO Council for final approval Minimal changes (related to ICAO processes) 6 6

Next Steps National implementation and compliance by States Continued research Cargo Bays have no viable solution yet Assessing low- or no-GWP options Monitoring inventories - ICAO will be asking its communities for halon supplies and needs and will provide to HTOC Continued ICAO-HTOC collaboration Next Stakeholder meeting is December 2011 HTOC participation from Russia and China
