The centre often feels quiet, as children are regularly out on visits to farms or climbing walls.Today pupils are visiting a local golf driving range.

Alex tells me staff have worked hard to make Springwell a place children are happy to come to every day."We often have to fight against thoughts that parents might have about what we are as a centre."There is a perception of a pupil referral unit as being prison-like, and we try to get away from that view as quickly as possible."

In the reception area a mother is dropping off her son, who is 13.Sam tells me her son has an autism diagnosis and struggles in larger groups, but has thrived since attending Springwell.

"I would constantly get phone calls when he was in mainstream school to come and get him because he was struggling and having a meltdown," she says.

"He really loves it here, I suppose because it's smaller and he gets more one to one."In the UK, SAF is mainly made from cooking oil, some of which is shipped from Asia, and shipping is responsible for 2% of global CO2 emissions.

Alternative methods of creating SAF require large quantities of electricity as part of the manufacturing process. This would involve a vast amount of renewable energy to make it sustainable."It's very hard, to think there is such a thing as a sustainable aviation fuel,” says Sir Dieter Helm. “There are aviation fuels that are less polluting than the ones being used at the moment, and you can use elements of biofuel and chip fat and so on.

"Think about the scale that's required to do it.”There is another more unexpected way that airlines could reduce emissions. That is, making their flight paths more direct to reduce fuel consumption.
