IATA’s blueprint for accelerating SAF production and adoption

Episode 86

Thursday, June 6, 2024 • Duration 01:15:27

In our first-ever bilingual episode, we talk to Preeti Jain, Head of Net Zero Transition Program at the International Air Transport Association (IATA). Jain provides an in-depth look at the challenges and opportunities in scaling up sustainable aviation fuel (SAF) to help aviation achieve its goal of net zero emissions by 2050.

The interview is presented in two parts: English followed by Hindi.

Jain discusses the current SAF landscape, highlighting the stark mismatch between demand and supply. Emphasising the need for greater SAF production, she estimates that a 1000-fold increase is required by 2050, amounting to roughly 300 new SAF plants each year. This rapid scale-up, however, is hindered by several challenges: inconsistent policy support, high capital costs and under-developed feedstock supply chains.

IATA’s strategy for overcoming these challenges involves a multi-pronged approach focusing on feedstocks, technology development, policy support, and collaboration across stakeholders. Jain emphasises the need for policies that encourage SAF production and adoption, and commends the U.S. Inflation Reduction Act and California’s Low Carbon Fuel Standard as good examples. She sees potential in leveraging existing refinery infrastructure for SAF production, and expects SAF’s cost to decline over time as more facilities are deployed and technologies mature.

Jain also discusses the potential for SAF to deliver benefits beyond emissions reductions, such as improved energy security and rural economic development, particularly in emerging economies with large agricultural sectors. She also emphasises the critical role of collaboration across the aviation industry, governments, and civil society to build a thriving SAF ecosystem.
