IS SAF JUST ANOTHER EXAMPLE OF GREENWASHING?
There’s been a lot of talk about “sustainable” aviation fuels - or SAF - recently, your publication included. Virgin Atlantic recently made headlines for operating the first 100 per cent SAF-fuelled flight across the Atlantic [see page 17], which has been lauded as a “step change” and a “milestone”.
But isn’t this just another example of greenwashing?
I understand the principle of SAF is that it uses alternatives to fossil fuels - but how much better for the environment are the emissions from say, used cooking oil or animal fats. And would vegans be happy to fly on aircraft powered by this method?
Another question that arises: where is the quality control on these materials? There have been worrying reports that much of this “used cooking oil”
