African fleet renewal delivers more emissions benefit than any SAF programme

Replacing a 25-year-old aircraft cuts more carbon than blending fuel into a modern one.

African carriers operate some of the oldest fleets in commercial aviation, and that fact is usually framed as a safety or reliability story. It is also the largest available emissions lever on the continent.

A 25-year-old narrowbody burns roughly 20–25% more fuel per seat than its current-generation replacement. No realistic SAF blend delivers that on an existing airframe.

The obstacle is capital, not intent. Fleet renewal requires financing that many African carriers cannot access at viable rates, which is why leasing structures matter more here than anywhere else.

Our read: development finance aimed at fleet renewal would buy more carbon reduction per dollar than the same money spent on SAF offtake.
