The World Travel and Tourism Council (WTTC) warned on May 15 that a shortage of sustainable aviation fuel (SAF) could increase airfares and restrict travel options.

Sustainable Aviation Fuel in the industry

In most areas in the aviation industry, there is a huge push towards net-zero and green commitments. Still, currently, according to a WTTC report, SAF accounts for just 0.3% of global jet fuel, or 1.25 billion litres. For context, the industry would need to be using 450 billion litres to meet airline net-zero goals.

It is of course a work in progress and nations are implementing measures to increase the use of SAF, by rolling out initiatives requiring airlines to use SAF in their fuel mix. Notably, EU airlines currently sit at a 2% SAF blend in 2025, escalating to 70% by 2050. China however requires airlines to be using a 15% SAF blend by the year 2030. Similar policies exist in nations like Sweden, Brazil, and Japan, whilst India and Turkey are currently exploring mandates.

How could the current status of SAF impact air travel?

The simple fact is, SAF production can cost up to 10 times more than conventional jet fuel. A lack of investment and infrastructure has not helped to mitigate this, WTTC president and CEO Julia Simpson says:

“Sustainable fuel is the single biggest game changer for travel and tourism, but right now, supply falls dangerously short of demand. Every hotel, tour operator, travel agency, cruise line and airline has a role to play. Sustainable fuel is not just an environmental necessity. It’s a business imperative. Governments must incentivise SAF production, not just set targets.”

There has been undeniable growth in SAF production and integration into the aviation industry in the last decade, but if the industry does not come together as a whole, meeting the government mandates to increase the SAF blend in fuel could increase the cost of air travel for consumers and limit their options.
