Neil Dickson, Environment Officer Environment Branch, ICAO Air Transport Bureau • The ICAO Airport Air Quality Manual • Emissions Inventories • Pollution Concentrations and Dispersion Modelling • Summary © ICAO 2014 • ICAO has been involved with airport- related emissions for many years. • Guidance material on airport-related air quality was published in 2011: – Help States implement best practices to assess airport air quality; – ICAO Doc 9889. (...) Emissions Inventories • The actual arrival and departure phases of operations may be more appropriate: – e.g. for departure: Engine start, Taxi to runway, Holding on ground Take-off roll to lift-off, Initial climb to power cutback. © ICAO 2014 • Emissions occur at multiple locations during various time periods; – Stationary sources such as generators; – Mobile sources such as the aircraft. • The dispersion of emissions requires both temporal and spatial considerations. Pollution Concentrations and Dispersion Modelling © ICAO 2014 • Atmospheric dispersion modelling is required to estimate the local ambient concentrations. • The results form the basis for LAQ impact studies – Used to demonstrate compliance with required regulations and standards. • Existing pollution concentrations can also be assessed by in-situ observation of ambient conditions – This assessment method can include contributions from other nearby and distant sources. • Modelling results and ambient observations can be used for evaluating existing or historical conditions. Pollution Concentrations and Dispersion Modelling © ICAO 2014 • Emissions inventory, concentrations and dispersion modelling, and ambient observation elements can be used individually or in combination. • The aim is to aid the process of understanding airport air quality, reporting, and compliance and/or mitigation planning. • Subsequent air quality mitigation can have beneficial results for the: – total emissions mass; – concentration model results; – measured pollutant concentrations.

To ensure the concentrators arrived as quickly and safely as possible, UNICEF and The UPS Foundation teamed up in a rapid logistics effort to send 500 concentrators to Kolkata, the capital of West Bengal, for distribution in the state. This delivery of oxygen concentrators was just the beginning of a response that saw UPS support the delivery of over 3,000 concentrators to India. (...) Those suffering from acute breathlessness get some relief when they are provided with oxygen from the concentrators.” UNICEF/UN0479958/Mitra Oxygen for the future  Oxygen concentrators are also an investment over the long-term.
