Mr. Willie Walsh:

Yes. I will put this into context. Very good research is done by Eamonn Brennan's team at EUROCONTROL. In continental Europe, especially France, there is a debate around whether we should stop short-haul flying and force people to travel by train instead of plane. If you stopped every flight in Europe of fewer than 500 km, which would include flights from Ireland, it would account for 24% of the flights, which only generates 3.8% of the CO2. Most of the CO2 produced by the airline industry is from flights of greater than 1,500 km. They account for 75% to 80% of the CO2. We will not see an electric or hybrid electric aircraft capable of flying those distances maybe ever, but certainly not in the timeframe out to 2050. That is why when we model our industry we can see the best option for it is the development of sustainable aviation fuels, through multiple pathways and feedstocks. Those could include e-kerosene produced from green hydrogen at some stage. Beyond 2050, maybe there will be hydrogen-powered aircraft. However, we are very different from road transport, where there are many options.
