New fuel, same planes: Inside the bid to clean up air travel with cooking oil and captured carbon
Aviation contributes approximately 2.5% of global CO2 emissions, a share expected to grow as other sectors decarbonize. Sustainable aviation fuel represents the most viable near-term climate solution for the industry since existing aircraft can use SAF without major redesigns. SAF is produced from renewable sources including cooking oil, animal fats, oil-rich plants, and waste materials, or even captured carbon, replacing fossil fuel extraction. Battery and hydrogen alternatives remain impractical due to insufficient energy density and infrastructure challenges respectively.
Key points
- Aviation accounts for ~2.5% of global CO2 emissions and rising
- SAF compatible with existing aircraft, no redesign needed
- Fuel sourced from cooking oil, waste, plants, or captured carbon
