“地沟油”正在成为飞机燃料，但数倍于航空煤油的成本困扰航司

Core Insights - The focus of the recent IATA annual meeting was on reducing the procurement costs of Sustainable Aviation Fuel (SAF) and establishing a shared responsibility mechanism among airlines [1] - SAF production is projected to reach 2 million tons by 2025, which will only account for 0.7% of total aviation fuel usage, indicating a need for exponential growth to meet the industry's net-zero carbon emissions target by 2050 [1][2] - The aviation industry is under pressure to reduce carbon emissions, with SAF being a key solution to decarbonization [1][2] SAF Production and Demand - SAF is derived from sustainable sources such as biomass and waste oils, and can reduce lifecycle carbon emissions by up to 85% compared to traditional fossil fuels [2] - The EU has set strict SAF usage targets, requiring a 2% blend by 2025, increasing to 6% by 2030, and 70% by 2050, which translates to a demand of nearly 1 million tons of SAF by 2025 [2] - China aims for a SAF consumption of over 20,000 tons in 2025, with a cumulative total of 50,000 tons, representing 0.2% of its annual aviation kerosene consumption [2] Industry Developments - Several Chinese airlines have conducted verification flights using SAF, with a pilot program initiated in September 2024 to incorporate SAF into domestic flights [3] - Domestic companies, such as Sinopec and Junheng Bio, are increasingly entering the SAF production sector, with Sinopec planning to produce 230,000 tons annually in collaboration with TotalEnergies [4][5] - China has established a SAF production capacity of 350,000 tons, with ongoing investments to expand this capacity further [4] Cost and Market Dynamics - The average cost of SAF is currently 3.1 times that of traditional aviation fuel, projected to rise to 4.2 times by 2025 due to compliance fees and decreasing traditional fuel prices [6] - The IATA estimates that achieving net-zero carbon emissions by 2050 could incur costs of up to $4.7 trillion if current SAF prices persist, highlighting the need for government incentives to stimulate market growth [6][7] - Industry experts emphasize the necessity for large-scale production and competitive pricing of SAF to meet carbon reduction goals, similar to the support provided for renewable energy sources [7]
