Might Sustainable Aviation Fuels (SAFs) Help Canada Reach Net-Zero Flight?

Imagine improving the aviation fuel to eliminate emissions. Well, so far, Sustainable Aviation Fuels (SAFs) can’t do that, but they are one of the aviation industry's most promising decarbonization strategies.

It will take more than efficiency improvements to eliminate aviation fuel emissions. Yet, SAFs, along with specific technological innovations, will be critical components of Canada's net-zero ambitions.



What Are Sustainable Aviation Fuels?

SAFs are renewable or waste-derived fuels produced using renewable feedstocks and advanced production methods. As such, they significantly reduce lifecycle emissions when compared with conventional jet fuel.


Both Canadian and international organizations view SAFs as the most promising option to reduce aviation industry emissions.


Canada Develops SAFs

In 2024, Parkland Corporation produced the first batch of domestically refined SAFs in Canada. They use canola and other renewable feedstocks, a major milestone for the sector.

Other major industry players include Air Canada, WestJet, Airbus Canada, and Pratt & Whitney Canada. Together, they work on collaborative initiatives to develop next-generation synthetic fuels and to test the compatibility of aircraft engines with higher SAF blend ratios.


Challenges for Future SAF Production for Global Net-Zero Targets

Certainly, current SAF production remains far below what’s required to support a global net-zero aviation sector. So, what’s holding us back?


  • SAF production capacity

  • Fuel costs for SAFs are more than conventional jet fuel prices

  • Still concerns about environmental effects related to feedstock production and land use


But, again, SAFs can’t be considered as a single, stand-alone solution.


Next Steps: Innovations Beyond Fuel

Fuel innovations for greater sustainability are critical. But they can’t accomplish full net-zero goals. So, efforts are ongoing to develop:

  • Aircraft engines with better fuel efficiency 

  • Alternative technologies like electric and hydrogen

  • Compatible with 100% SAF 

  • Operational improvements like routing, lighter aircraft, and hybrid engines 


Conclusion

Achieving net-zero aviation by 2050 requires systemic change globally across the entire industry. SAFs, technological innovation, government policy, and consumer demand all contribute. The future of sustainable aviation depends on a combination of solutions. Not one single technology.
