Aviation is one of the fastest-growing sources of greenhouse gas emissions globally, contributing around 2.5% of total global CO₂ emissions. In China, aviation contributes about 12% of the nation’s transport-related emissions, making it a critical sector to address as the country aims for carbon neutrality by 2060. Despite ambitious global targets, international sustainable aviation fuel (SAF) production is falling behind schedule. A recent report highlights that worldwide production could fall 30% to 45% short of the global aviation sector’s 2030 goals due to high production costs, economic uncertainty, and slow adoption rates.
