ATA wants 'more contrails data'

The International Air Transport Association (IATA) wants 'urgent action' on aviation contrails to develop effective mitigation measures. 

 

The newly-released IATA report 'Aviation Contrails and their Climate Effect: Tackling Uncertainties and Enabling Solutions' says more collaboration from interested parties is needed and highlights the complexity of contrail science.

It says there are 'gaps' in the understanding of how contrails form, or when they could persist, and how they impact the climate. It also says there's a lack of good data on atmospheric conditions (particularly humidity and temperature at jet cruising altitudes) that hinders precise contrail forecasting. 

“The industry and its stakeholders are working to address the impact of non-CO2 emissions on climate change, particularly contrails, (but we need to) better understand how and where contrails form and shrink the uncertainties related to their climate impact," said Willie Walsh, IATA’s director general. 

'Aviation Contrails and their Climate Effect: Tackling Uncertainties and Enabling Solutions' is available on IATA’s web site and will be discussed at the upcoming IATA agm in Dubai, 2-4 June.
