‘Trailblazing’ net-zero transatlantic flight powered by cooking oil to take off in 2023

The world’s first net-zero transatlantic flight will take to the skies next year, the UK government has pledged.

The UK-US flight will be powered by 100 per cent sustainable aviation fuel (SAF), a low-emissions fuel made from waste materials like used cooking oil.

Such a flight will “usher in a new era of guilt-free flying in the coming decades,” the Department of Transport declared.

What are SAFs?

SAFs are produced from sustainable feedstocks like used cooking oil, agricultural waste, and household trash such as packaging, food scraps, and textiles.

SAFs still give off carbon emissions when burnt. However the International Air Transport Association (IATA) estimates that they curb emissions by roughly 80 per cent over the course of the “fuel life-cycle.”

This is because they are made from waste products, where the carbon has already been emitted, or from plants that absorb carbon dioxide while they grow.

SAFs are currently mixed – at a 50 per cent ratio – with traditional fossil fuels.

The UK government have offered £1 million (€1.18 million) to whichever transatlantic airline can deliver a 100 per cent SAF flight in 2023.

Combined with “greenhouse gas removals, 100 per cent SAF will enable the delivery of a net zero flight”, a government spokesperson said

Transport secretary Grant Shapps promised to fast-track testing and approvals for SAF technology.

“This trailblazing net zero emissions flight, a world first, will demonstrate the vital role that sustainable aviation fuel can play in decarbonising aviation in line with our ambitious net zero targets,” he said.

Further details on when the flight will take-off will emerge in coming months.

Will we ever fly guilt-free?

Aviation accounts for about two per cent of the world’s global carbon emissions. A Lund University study found that avoiding just one transatlantic flight saves eight times more greenhouse gas emissions in a year than recycling.

But IATA – whose members carry more than 80 per cent of the world’s flyers – plans to reach net zero by 2050.

SAFs are often touted as the best route to decarbonisation. Oneworld alliance providers – including British Airways, American Airlines and Finnair – have pledged to use 10 per cent SAF by 2030.

The European Commission’s ‘ReFuelEU’ initiative proposed mandating fuel suppliers to use 2 per cent SAF from 2025 – gradually increasing to 63 per cent in 2050.

But current uptake is extremely low. In 2019, SAF accounted for just 0.1 per cent of all jet fuel used worldwide. Scaling up is a problem, as SAFs are more than twice as expensive as normal fuels.

The UK government has asked the aviation industry to bring at least three commercial SAF production plants online in Britain by 2025. It has also pledged £180m (€212m) to the SAF industry.

However, the Climate Change Committee (CCC) estimates that the UK aviation industry will use just seven per cent SAF by 2030.

Meanwhile, climate consultancy Element Energy has slammed the government for its “unrealistic” jet-zero plan.

In a report released today, they accused the government of relying on unproven technology, and urged them to halt planned airport expansions at Gatwick and Luton.

Climate-conscious travellers are increasingly turning to other modes of transport, including train travel.
