As airlines encourage us to pay additional fees towards sustainable aviation fuel, how successful is the initiative to wean air travel off fossil fuels?

REFUELLING sustainability

In recent months many airlines have started to offer corporate customers the opportunity to partner with them in sourcing sustainable aviation fuel (SAF). For companies looking to lower their carbon emissions (20 per cent of Fortune 500 companies have set a climate commitment for 2030), it is a way of reducing the emissions caused by their employees travelling. For airlines it means they can reduce their Scope 1 emissions – meaning those stemming directly from its core business – while the corporate reduces their Scope 3 emissions caused by travel. But what effect will buying small amounts of SAF have on the overall emissions that aviation creates, and should you be pushing your company to do the same, or perhaps topping up those contributions by buying SAF as an offset for your own travel?

Aviation accounts for 2-3 per cent of global carbon emissions today, but there is a risk that this could rise to more than 20 per cent by 2050. At present, these emissions are small compared to transport as a whole (around 25 per cent in the European Union), but proportionally they will rise as those other industries reduce their emissions through electric vehicles and biofuels.

Sustainable aviation fuel is seen as the mid-term future for commercial aviation, until new technology – both electric and hydrogen – is brought into mainstream commercial use. At present, SAF makes up only 1 per cent of fuel used worldwide. As the International Air Transport Association (IATA) puts it: “Insufficient supply and high prices limited airline uptake to 120 million litres in 2021– a small fraction of the 350 billion litres that airlines would consume in a normal year.”

The rail thing - Why airlines and train companies are partnering to increase options for travellers on short journeys

An intercity flight connection operated by train would have been almost unthinkable in the early 1990s, but in 2024 it will increasingly be the default experience at many European hub airports. European nations have been among the world's leaders in adopting high-speed rail for short-distance trips, along with Asian countries such as Japan and China.

Adventures in Albania - From paranoid dictatorship to dream travel destination, why the Balkan nation is ready for its moment in the sun

Over the past few years, tourism has shot up stratospherically; recent figures from the European Travel Commission show it's grown 86 per cent since 2019. Its GDP per capita has also been increasing, and last year stood at US$8,800, while the average monthly salary is now around 84,000 lek (£704). Foreign direct investment is also on the rise, with countries including Switzerland, Italy, and the Netherlands targeting sectors such as energy, mining, information and real estate to a value of around US$1.5 billion in 2022, according to UNCTAD's World Investment Report. Not bad for a country which used to depend on foreign food aid.
