SUMMARY:Aviation and the Environment: New Regulatory Standard for Aircraf
 t Engine non-volatile Particulate Matter Emissions

DESCRIPTION:The civil aviation sector has been forecast to grow at the ra
 te of ~5% per year for the foreseeable future. There are increasing conc
 erns about the impact of aircraft emissions on local air quality\, healt
 h\, and climate change. Aircraft engines are a unique source of emission
 s both at ground level in the urban environment and at cruise level alti
 tudes. The characteristics of aircraft engine emissions are distinct fro
 m other sources and have been shown to vary with engine type\, fuel comp
 osition\, and engine thrust setting.\n \nThe International Civil Aviatio
 n Organization (ICAO) Council’s Committee on Aviation Environmental Prot
 ection (CAEP) has developed regulatory standards to limit or reduce the 
 impact of aviation emissions on local air quality and aviation greenhous
 e gas emissions on the global climate. This includes a new regulatory st
 andard for non-volatile Particulate Matter (nvPM) number and mass-based 
 emissions from civil aviation aircraft engines > 26.7kN thrust. In this 
 specific context\, nvPM is defined as the emitted particles at the aircr
 aft engine exhaust nozzle exit plane that do not volatilize below a temp
 erature of 350°C. The development of the standardized sampling and measu
 rement methodology to be used for aircraft engine emission certification
  will be discussed. There is also a large effort underway worldwide to r
 educe the environmental impacts of aviation through the use of sustainab
 le alternative fuels. Alternative fuels blended with conventional Jet A/
 Jet A-1 (up to 50%) have been approved for use in the commercial aviatio
 n sector. The development of a new international regulatory standard for
  nvPM emissions from civil aviation aircraft engines will be discussed i
 n the context of changes in jet fuel composition.
