The implications of the variability of national and regional air quality regulations on the modelling of airport air quality within global aviation/environment models
TL;DRAbstract
This paper discusses the variability of the limit values for ambient air NO2 concentrations internationally and the implications of this variability. The particular concern addressed is the substantial variability (annual average of 40 μg / m 3 in the UK and Europe generally and 100 μg / m 3 in the US) on the assessment of air quality in the vicinity of airports. An attempt will be made to assess the economic effects of this difference. Much of the discussion and argument regarding the expansion of Heathrow airport centres on local air quality and would not arise if the US federal regulations were being used. The paper also addresses the topical subject of how these national and regional variabilities can be incorporated in an equitable manner into global models of the impact of aviation on the environment
