The transportation sector accounts for 14% of the world's GHG emissions. This is why governments and states worldwide are taking measures to lower GHG emissions through subsidies and legislation. In fact, 137 countries have pledged to be carbon-neutral, and most are aiming for a year 2050 deadline. 

 

Aviation is responsible for 8% of the transport sector's emissions, so there is no way the aviation industry can fly under the radar. Change is coming, and sustainable aviation fuels (SAF) will be in high demand. The demand for SAF is projected to be around 15 Mt in 2030 and 200 Mt in 2050, and in the long run, both biojet and eJet fuels are expected to overtake fossil jet fuel. 

So, will there be clear skies ahead?

According to the legislators, yes. Blending mandates for sustainable aviation fuel are being discussed and implemented globally. The EU aims for 65% in 2050, and some countries have stated even more ambitious SAF targets. And there is a strong interest from corporates, airlines, and cargo carriers to explore and increase the use of sustainable aviation fuel.

As seen above, there are some regional differences concerning the SAF blending mandates, but the overall picture is clear. Change is on the horizon.

Feedstock availability can cause turbulence. 

SAF can be produced from various renewable feedstocks, including vegetable oils, waste oils and fats, solid biogenic waste, industrial flue gases, and CO2 , renewable electricity and water for example. As the market for and production of SAF will increase, so will the need for suitable feedstocks. Other segments and industries like road transport, marine fuel and petro-chemicals are pursuing the same feedstocks for different purposes. That can become a seriously limiting factor in reaching the goals.

 

What does this have to do with legislation, you might think? The use of feedstock, in particular first-generation bio-feedstock, is highly regulated in some parts of the world like the EU with direct implications for the biofuel production required to supply mandated volumes.

LEGISLATION IS INVOLVED IN EVERY SINGLE STEP OF RENEWABLE FUEL PRODUCTION
New pathways and innovation are key.

Directives like the European Renewable Energy Directive (RED III) will limit the use of feedstocks that could be used for other purposes – like feeding a growing population. Specifically, the RED III includes sustainability criteria regarding indirect land use change (ILUC) and has caps on using edible oil for fuel production.

These and other regulations will limit feedstock use. This means that all pathways, technologies, and roads to producing fuels with the lowest carbon intensity need to be explored and developed to make ends meet.

Consider GHG savings and Carbon Intensity. 

 

Immediate GHG savings are still the priority when producing sustainable aviation fuels. The European Union is looking at savings targets like 65% for biojet fuel and 70% for eJet fuel. And the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) requires GHG reductions of at least 10% compared to the conventional aviation fuel.

 

SAF can reduce greenhouse gas emissions and even be carbon negative, depending on the production methods and use of feedstock and technology. But there are still emissions throughout the supply chain, and measuring the carbon intensity (CI) is necessary to fully evaluate the lifecycle GHG emissions from fuels.
