The cost of adopting sustainable aviation fuel

January 21, 2025

The adoption of sustainable aviation fuel (SAF) offers a promising path towards decarbonising air travel, but it also presents significant challenges for tourism destinations, particularly those dependent on aviation connectivity. One of the most pressing concerns is the cost disparity between SAF and conventional jet fuel. This price difference can have profound implications for tourism-dependent economies.

SAF currently costs more than traditional aviation fuels, making it less attractive in the short term. This cost premium is a critical concern for destinations that rely heavily on air travel, especially for low-cost and regional airlines. Higher fuel costs translate into increased ticket prices, potentially reducing the affordability of air travel for a broader segment of travellers. For destinations reliant on budget tourism or high volumes of visitors, this poses a threat to sustaining tourism numbers.

Climate resilience directly contributes to the stability of tourism destinations. By implementing measures to mitigate and adapt to climate change, destinations can protect their natural resources, which are often the primary attractions for tourists. For instance, destinations like Puerto Rico and the Philippines have developed sophisticated resilience strategies that include climate risk assessments, biodiversity conservation plans, and hazard mapping.1,2 These measures help preserve beaches, forests, and other natural assets that are crucial for tourism.

3 actionable steps that SMEs can take to align with SAF

  • Advocate for green travel partnerships: SMEs can collaborate with airlines and travel agencies that prioritise SAF usage. By promoting eco-friendly travel options to customers, SMEs can strengthen their sustainability credentials.
  • Invest in SAF certificates: While direct investment in SAF production may be beyond an SME’s reach, they can participate in "book and claim" systems or SAF certificate schemes. This allows them to indirectly support SAF adoption and market their contribution to reducing aviation emissions.
  • Engage in regional sustainability initiatives: SMEs can join local or regional tourism and energy networks working on SAF feasibility studies or renewable energy projects. By participating in such initiatives, they can advocate for localised SAF production.

As airfares rise due to the incorporation of SAF, demand for air travel could decline, particularly among price-sensitive travellers. Additionally, reduced connectivity due to higher operating costs for airlines could isolate remote or less accessible destinations, further exacerbating the issue.

Governments worldwide are introducing mandates for SAF usage to meet sustainability targets. While well-intentioned, these regulations can create logistical challenges for airlines and destinations, particularly where SAF production and supply chains are underdeveloped. This could hinder compliance and add operational complexities.

Emerging solutions like the book and claim system, which decouples SAF production from its physical usage, offer potential. However, these schemes require robust verification and regulatory frameworks to function effectively and gain industry-wide acceptance.

Broader implications

Tourism operators and businesses may need to adapt their models to align with sustainable travel trends. This could involve promoting SAF adoption through investments or partnerships with airlines. However, smaller operators might struggle with the financial burden of these adjustments, creating disparities within the tourism sector.

To address these challenges, tourism destinations must adopt a proactive and collaborative approach. Governments, airlines, and tourism stakeholders should work together to establish localised SAF production and supply chains. Incentives to reduce SAF costs, investments in renewable energy for SAF production, and public-private partnerships can help bridge the affordability gap.

While SAF holds transformative potential for aviation and tourism, its adoption is fraught with challenges that destinations must carefully navigate. By fostering innovation, encouraging collaboration, and addressing cost and supply barriers, tourism-dependent economies can mitigate risks and transition toward sustainable aviation without compromising its global appeal.
