Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to the report entitled the current state of scientific understanding of the non-CO2 effects of aviation on climate published in December 2018, what assessment he has made of the implications for his Department’s policies of that report's findings on the non-CO2 effects of aviation on the climate.

The Government’s Jet Zero Strategy recognises that aviation creates both CO₂ emissions and non-CO₂ climate impacts and commits to addressing non-CO₂ by better developing our understanding of its impacts and potential mitigations.

All relevant evidence was considered in the development of the Jet Zero Strategy, and uncertainties remain over the magnitude of non-CO₂ impacts on the climate.

We will continue to engage closely with the science, working closely with academia and industry, including as to how to quantify and track the impacts of non-CO₂.
