Core Viewpoint - The aviation industry faces significant challenges in reducing carbon emissions, and Sustainable Aviation Fuel (SAF) is recognized as a key pathway for achieving this goal. The development of SAF in China has made positive progress, driven by national policies and market demand [2][3]. Group 1: Current Status of SAF in China - The aviation sector accounts for approximately 99% of its carbon emissions from fuel consumption, with SAF capable of reducing carbon emissions by 80% to 85% compared to traditional jet fuel [3]. - Currently, domestic SAF production only constitutes 0.17% of total aviation fuel, which is below the global average of 0.3%, indicating a supply capacity issue [4]. - The production cost of SAF in China is 3 to 5 times higher than traditional jet fuel, with SAF prices projected to be around 20,000 yuan per ton by 2025, compared to an average of 5,507 yuan per ton for domestic jet fuel [4]. Group 2: Challenges Facing SAF Development - The SAF industry in China is hindered by insufficient supply capacity, high application costs, and an incomplete carbon trading system [4]. - There is currently no market-based pricing and procurement mechanism for SAF, which limits the willingness of airlines to adopt it [4]. - The lack of a domestic SAF certification standard means that Chinese producers rely on foreign certification, weakening their competitive position internationally [5]. Group 3: Recommendations for SAF Advancement - To overcome development bottlenecks, it is suggested to enhance research and development of new SAF technologies and processes, integrating them into national key research plans [6]. - Improving supply capacity involves increasing research investment and developing alternative raw materials such as agricultural waste and algae [6]. - Establishing a market-oriented pricing and procurement mechanism for SAF is essential, along with providing financial subsidies and tax reductions for eligible SAF producers and users [6]. - The SAF application should be included in the national carbon market, with a focus on creating a market mechanism for carbon reduction benefits [6]. - Developing a domestic SAF certification system that aligns with international standards is crucial for enhancing China's influence in international SAF regulations [7].
