BRUSSELS (Reuters) -The European Union has offered to subsidise airline purchases of more than 200 million litres of sustainable aviation fuels to encourage carriers to swap kerosene for cleaner alternatives, Reuters calculations show.
The calculations, based on European Commission data, suggest that the subsidies could trigger a significant boost to airline demand for sustainable aviation fuels (SAF), given the volume equates to about 15% of global SAF production.
Global SAF output last year totalled 1.3 billion litres, according to airline industry association IATA.
The EU has earmarked revenue from the sale of 20 million carbon emissions permits to help airlines to cover the price gap between conventional kerosene and more expensive SAF on flights within Europe.
Reuters calculations showed these subsidies would cover purchases of up to 216 million litres of e-fuels - synthetic fuels made using captured CO2 emissions - or as much as 2.6 billion litres of biofuels.
The EU subsidies cover up to 6 euros per litre for e-fuels and 0.5 euros per litre for biofuels.
Aviation is among the hardest sectors to decarbonise, with zero-emission aircraft not expected this decade.
Sustainable fuels, which have net-zero emissions or lower emissions than fossil fuel kerosene, can help to reduce air travel's carbon footprint in the near term. However, SAF costs three to five times more than traditional jet fuel and makes up only 0.3% of global jet fuel supply.
Airlines have warned that EU targets to use more SAF are therefore impossible to meet, though a Boston Consulting Group report this year found that the sector is investing only 1%-3% of revenue or budget allocation in SAF.
The EU requires 2% of fuel made available at EU airports to be SAF in 2025, rising to 6% in 2030.
Airlines must buy permits from the EU carbon market to cover their emissions from European flights. Until last year, the EU gave airlines most permits free of charge, but it is now phasing out free permits to drive faster emissions reductions.

The EU has offered to subsidise airline purchases of over 200 million litres of sustainable aviation fuels to encourage airlines to transition from kerosene to cleaner alternatives.
The EU subsidies cover up to 6 euros per litre for e-fuels and 0.5 euros per litre for biofuels, aimed at bridging the price gap with conventional kerosene.
The EU mandates that 2% of fuel available at EU airports must be sustainable aviation fuel by 2025, increasing to 6% by 2030.
Airlines have expressed that the EU's targets for sustainable aviation fuel usage are impossible to meet, with a report indicating the sector invests only 1%-3% of revenue towards SAF.
Global sustainable aviation fuel output reached 1.3 billion litres last year, highlighting the growing but still limited production capacity in the industry.
