Christopher Surgenor, the Programme Director for Aviation Carbon Events and Editor of GreenAir News, is at the forefront of discussions on sustainable aviation within the industry. He emphasizes the importance of aligning government and industry efforts to achieve net-zero emissions by 2050. Key challenges include scaling sustainable aviation fuel (SAF) production, attracting investment, improving fuel efficiency, and reforming airspace operations. While SAF and green hydrogen hold promise, their mainstream adoption faces hurdles such as low production levels, high costs, and lack of government support. Christopher highlights the need for rapid ramp-up in SAF production to meet emission reduction targets. Green hydrogen, essential for clean aviation fuels, is still in its early stages. Government interventions like blending mandates in the EU and the UK, tax incentives in the US, and global frameworks by ICAO are shaping aviation policies to reduce emissions. These measures aim to stimulate SAF production, incentivize airlines to use SAF, and promote global collaboration towards a more sustainable aviation future.
