Aviation is a few percent of CO₂ — highly skewed flyers
Most people did not fly this year. Frequent flyers dominate aviation emissions.
Most people on Earth did not fly in 2026. Yet aviation still accounts for roughly 2.5% of global energy-related CO₂ — a footprint dominated by a small group of frequent flyers. This grid puts that 2.5% beside the other 97.5% of global CO₂: small in share, highly skewed in who emits it.

Context
The skew is the story: because most of the world's population took no flights in 2026, aviation's emissions are concentrated in a small frequent-flyer minority. A few percent of global CO₂ therefore reflects the travel habits of a narrow slice of humanity.
On the grid, aviation's ~2.5% share is spotlighted against the remaining ~97.5% of global CO₂, banded by region: Asia & Pacific 50.7%, Africa 27.3%, and the Americas 19.5%.
The headline figure follows the IEA's aviation overview, which rounds aviation to roughly 2.5% of energy-related CO₂; here it is expressed as a share of global fossil CO₂ emissions. Even a few percent of the planetary total is a large absolute footprint.
