Aviation: Climate Change

(asked on 25th January 2021) - View Source

Question to the Department for Transport:

To ask Her Majesty's Government what discussions they have had with the International Civil Aviation Organisation about the inclusion of indirect non-CO2 climate impacts of aviation, such as climate forcing caused by condensation trails, in the Carbon Offsetting and Reduction Scheme for International Aviation.


This question was answered on 3rd February 2021

Currently, the International Civil Aviation Organisation (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) only applies to CO2 emissions. Due to the uncertainties surrounding aviation’s non-CO2 climate impacts, ICAO does not include these in its climate policies.

The UK continues to negotiate in ICAO for increased environmental ambition and supports continued work on aviation’s non-CO2 climate impacts and possible mitigation measures, taking into account their trade-offs with CO2. As a UN specialised agency, ICAO’s policies are the result of extensive technical work and negotiation between its Contracting States.
