#1ایکان ICAO ENVIRONMENT MAURITIUS ACTION PLAN RK SEWRAJ Divisional Head ATM Civil Aviation Department Republic of Mauritius Action Plan on Emissions Reduction#2ایکان . ICAO ENVIRONMENT STAKEHOLDERS THREE MAIN STAKEHOLDERS The Department of Civil Aviation which is the regulatory body and the provider of air navigation services; Our National Carrier, Air Mauritius which is the only airline operator in Mauritius; and . Sir • Airports of Mauritius (AML)) aerodrome operator for Ramgoolam International Airport. the licensed Seewoosagur#3ایکان . ICAO ENVIRONMENT ACTION PLAN In line with the broad international consensus, the Action Plan sets an aspirational goal to improve fuel efficiency from a 2007-2012 baseline by an average annual rate of at least initially one percent per year until 2020. To help ensure we reach this goal, the Action Plan identifies three key measures that are expected to have the greatest environmental impact: Modernise Airport facilities introducing new taxiways; More Efficient Air Operations; and Improved Capabilities in Air Traffic Management#4ایکان ICAO ENVIRONMENT ACTION PLAN CONSTRAINTS We have had the close collaboration of our main stakeholders. We did encounter some difficulties to finalise the action plan. Our main problem was how to quantify those mitigation measures, how to calculate how much fuel will be saved after implementing each of these eight measures. E.g. The Airport operator has improved the aerodrome infrastructure with new taxiways but were unable to quantify these measures in terms of fuel savings.#5ایکان ICAO ENVIRONMENT ACTION PLAN CONSTRAINTS A working group was set up to analyze the measures and with the help of statistics from the Air Traffic Management and a round table involving pilots from National airline with the personnel from ATM, we managed to work out figures regarding fuel efficiency related to respective measures. We were also assisted by specialists from the Ministry of Environment to assist us regarding specific technical matters.#6ایکان ICAO ENVIRONMENT MEASURES Measure 1: Construction of a parallel taxiway and additional Taxiways & commissioning of these TWYS. Measure 2: Pre departure planning Flow management involving adjacent TMA Measure 3:Continuous Descent App & Continuous Climb Departures Measure 4: Awareness building among ATM staff#7ایکان ICAO ENVIRONMENT MEASURES Measure 5: Upgrading avionics capabilities of fleet to meet RNP to fly direct routes. Measure 6: Introduction of Taxi in on one engine for the ATR aircraft Measure 7: Operational flight Plans (OFPS) for long flights destination were revisited and optimised routes retained.

Our FIR covers a very vast area where the benefits to many international airlines are really tangible. (E.g. UPR) The Action Plan is a living document and will be reviewed on a regular basis through: Annual reporting on the progress towards achievement of the Action Plan's fuel efficiency target; An audit that will occur at least once over; and Semi-annual meetings between different stakeholders creating a synergy#18ایکان ICAO ENVIRONMENT CONCLUSION Air Mauritius has provided fuel statistics for the past seven years including RTK. Air Mauritius projected growth for the next five years has targeted 4-5% in seat capacity but is subjected to adaptations based on evolution in economic/market conditions. The expected result has been computed using Method 1 from the ICAO Excel template, by extrapolating the baseline (2007-2012), applying the assumption that the traffic growth forecast for National carrier is 4.5% (Air Mauritius projected growth) and that the intended mitigation measures would initially aggregate to around 1% fuel saving annually.#19ایکان ICAO ENVIRONMENT CONCLUSION The preparation of the action plan has resulted in a closer coordination between different stakeholders thus generating a better synergy. The main stakeholders have realised the importance of this action plan and the associated benefits and have decided that it should be an on- going process to review our course of action through close collaboration and more regular discussions to improve operation efficiency and need to identify future projects such as extending Taxiway Y to the threshold RWY 14 or renewal of fleet among others.#20ایکان ICAO ENVIRONMENT NEW PROPOSED MEASURES Measure 1: Refleeting of Air Mauritius Aircraft Measure 2: Restructure of the Air Mauritius Flight Information Region Measure 3: Dynamic Flight Plan Measure4: Optimised of Aircraft Maintenance- Engine Wash#21ایکان ICAO ENVIRONMENT Methodology Historical data from 2007-2019 ICAO Environmental Benefit Tool (EBT) has been used in developing and forecasting the future baseline fuel consumption.

Operational improvement measures will lead to a reduction of CO2 emissions of around 1.64% by 2050. Overall CO2 emissions, including the effects of new aircraft technology standards and operational improvement measures, are projected to improve to lead to a 5.94% reduction in 2050 compared to the baseline.#29ایکان ICAO ENVIRONMENT on Action Plan Emissions Reduction THANK YOU
