Leo Varadkar (Dublin West, Fine Gael) | Oireachtas source

I do not think a unilateral approach from Ireland would work in that regard. What might make more sense would be a tax or a requirement that sustainable aviation fuels be used over time. That might be a more realistic approach than the sledgehammer approach which would probably essentially say that Ireland is closed to investment from major companies into the future.

On the energy treaty, I am not aware of any proposals to withdraw from that.
