2. 2 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 2 Overview Global Aviation and the Environment Atlantic Interoperability Initiative to Reduce Emissions (AIRE) Asia and South Pacific Initiative to Reduce Emissions (ASPIRE)

3. 3 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 3 Global Aviation and the Environment The air transportation industry is essential for future economic growth and development, as aircraft carry approximately 40% of the value of all world trade. Last year 2.2 billion people flew on the world’s airlines, more passengers than ever before, with predictions of 9 billion passengers by 2025 The United Nations Intergovernmental Panel on Climate Change (IPCC) attributes nearly 3% of global greenhouse gas emission (mostly from carbon) to aviation As global aviation continues to grow and become a vital part of the worldwide economy, pressure to address environmental impacts will increase

4. 4 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 4 ICAO Strategic Objectives In Support of ICAO’S Strategic Objectives –Minimize the adverse effect of Global Civil Aviation on the environment –Enhance the efficiency of aviation operations

5. 5 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 5 AIRE Background Hasten development of operational procedures to reduce aviation’s environmental foot print on a “gate-to-gate” basis Quantify environmental benefits to aid in formulation of potential business cases Accelerate incorporation and worldwide interoperability of procedures/standards Capitalize on existing technology on either side of Atlantic Identify implementation issues, obstacles, choke points, metrics and solutions

10. 10 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 10 Asia and South Pacific Initiative to Reduce Emissions (ASPIRE) After the launch of AIRE in June 2007, a counterpart program in the Asia Pacific region was envisioned to leverage the efforts of existing North and South Pacific informal working groups (IPACG and ISPACG) and encourage a stronger focus on environmental benefits This Asia Pacific program became known as the Asia and South Pacific Initiative to Reduce Emissions, or ASPIRE High level statement on ASPIRE collaboration was signed on February 18, 2008 in Singapore between the FAA, Airservices Australia, and Airways New Zealand. Extended participation is needed and encouraged from Asia Pacific ANSPs, airlines and industry in order to fully progress operational emissions reduction initiatives. Initial ASPIRE efforts will focus on South Pacific initiatives, with future expansion to the North Pacific and the rest of the Asia Pacific region.

11. 11 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 11 ASPIRE Objectives Hasten development of operational procedures to reduce aviation’s environmental foot print on a “gate-to-gate” basis – covering each stage of airport operations: surface, departure, en route, arrival. Accelerate incorporation and worldwide interoperability of procedures/standards. Capitalize on existing technology in place across the Pacific. Provide a systematic approach which combines a set of short, medium, and long-term initiatives to enhance environmental and efficiency performance. Better identify issues, obstacles, choke points, metrics and solutions through cross-fertilization of demonstrations, development and flight trials in the Asia Pacific region.

12. 12 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 12 ASPIRE Candidate Initiatives Performance Metrics User Preferred Route (UPR) Expansion Dynamic Airborne Reroute Programs (DARP) Tailored Arrivals End-to-End Demonstration

13. 13 Federal Aviation Administration APEC Transportation Working Group (TPTWG) April 3-4, 2008 13 Performance Metrics Highest priority initiative projected under ASPIRE Metrics will catalog the efficiency and emissions gains to date since the introduction of the following South Pacific initiatives: –Dynamic Airborne Reroute Program (DARP) –User Preferred Routes (UPR) –30nm lateral/30nm longitudinal separation Goal is to formalize emission gains so far and to create a common baseline for future work Requires participation and data from all ASPIRE partners
