He said there were applications for the use of municipal waste, which has been investigated in terms of certification, and also other pathways that use forestry residues, agriculture residues.
The energy transition is key to sustainable aviation fuel, with IATA's website saying it can reduce emissions by up to 80 per cent during its full life cycle.
Global food security has turned the spotlight on how sustainable aviation fuels are sourced.
He said that the criteria developed for sustainable aviation fuels are probably more stringent than for other uses of renewable fuels.
They're more exhaustive and we make sure there is no competition for crops, in terms of land or food use or water, he said.
He added that the criteria ensure that the credentials of sustainable aviation fuel are very robust. There are also organisations that certify the fuels and provide the life cycle analysis of the cleaner alternative, which involves evaluating the environmental impact of a product from start to end.
As the industry moves towards greener skies, Mr Mistry called for the production of sustainable aviation fuel to be ramped up.
He said that we had an increase of over 200 per cent in terms of production compared to last year, but what we need is continued growth in that production.
He said that the industry needs to be at the projected path that it needs to be at by 2030 due to the expected refining capacity between now and 2027 of renewable fuel.
He said that the capacity for renewable fuels is going to be there.
He noted that more countries are entering the market because of the fact that most of the production capacity has been in Europe and the United States. How much of the output of renewable fuel capacity will be sustainable aviation fuels? He asked.
