IATA: SAF Production Stagnates at 0.8% of Global Fuel Use

IATA Reports Stagnant SAF Growth

The International Air Transport Association (IATA) has released new estimates indicating that global production of Sustainable Aviation Fuel (SAF) is projected to reach 2.4 million tonnes in 2026. This figure represents a marginal contribution, accounting for just 0.8% of total global aviation fuel consumption. The data, presented at the IATA 82nd Annual General Meeting (AGM) in June 2026, underscores the significant gap between the industry's net zero 2050 targets and current production realities.

The Cost of Underutilization

Willie Walsh, the Director General (DG) of IATA, has sharply criticized the current trajectory of aviation decarbonization. According to IATA's official pressroom, the industry faces a $4.3 billion premium cost for SAF in 2026 alone. Walsh attributed this slow progress to ineffectively sequenced government policies and a lack of interest from major oil producers.

Research from the IATA Sustainable Aviation Fuels portal reveals that total installed production capacity for 2026 is expected to exceed 9 million tonnes. However, this capacity remains heavily underutilized for aviation because current regulatory frameworks incentivize the production of renewable diesel, which is often more economically attractive for refineries. This structural imbalance leaves over 6.6 million tonnes of potential capacity effectively stranded from the aviation sector.

Regulatory Context and Market Dynamics

IATA argues that regional mandates, such as ReFuelEU Aviation, often increase compliance costs without ensuring a corresponding growth in supply. Instead, the association advocates for a globally recognized book-and-claim system to decouple physical delivery from environmental attributes. This would allow airlines to purchase SAF credits regardless of local supply constraints.

Historically, the industry has struggled with such transitions. In 2012, the introduction of the European Union Emissions Trading System (ETS) for aviation faced massive international backlash, leading to a temporary suspension for non-European flights. This precedent highlights the difficulty of enforcing regional mandates in a globalized industry. Meanwhile, environmental non-governmental organizations argue that SAF reliance ignores the need for demand management, while energy sector analysts maintain that renewable diesel remains the more rational economic choice under current policy incentives.

The Economics of Decarbonization

What Comes Next for IATA and SAF

The industry is now looking toward several critical milestones. The International Civil Aviation Organization (ICAO) has scheduled a Long-Term Aspirational Goal (LTAG) checkpoint for 2030 to review progress toward emissions targets. Additionally, Willie Walsh is confirmed to step down from his role as IATA Director General in the third quarter of 2026. These events will likely dictate the next phase of the industry's lobbying efforts regarding renewable diesel incentives and the standardization of global SAF credits.

Why This Matters for Global Airlines

For global airlines, the disparity between SAF availability and mandate requirements poses a significant risk to operating margins. The projected $4.3 billion cost premium is expected to be passed on to passengers, potentially impacting ticket prices and demand. As regulators continue to push for tighter environmental compliance, the aviation industry remains trapped between the urgent need for direct emissions reductions and a supply chain that currently prioritizes other fuel products.
