The aviation sector plays a crucial role in global connectivity, but it also contributes significantly to carbon emissions. Decarbonizing aviation is essential, and this journey involves enhancing fuel efficiency through design improvements and optimized routing. While current measures have reduced emissions per passenger, the growing air traffic necessitates zero-carbon alternatives. Sustainable aviation fuel (SAF) offers a promising solution, with diverse value chains sourced from various feedstocks. Additionally, synthetic SAF production requires substantial amounts of clean hydrogen and zero-carbon electricity. Stakeholders must collaborate for a successful transition, with government mandates and business participation driving investment in sustainable aviation. Private sector involvement is key in stimulating demand and innovation in the journey towards zero-carbon aviation.
