Frequently Asked Questions
Why does flight distance affect per-mile emissions?
Shorter flights are typically less fuel-efficient per mile due to the high fuel cost of takeoff and climb relative to a shorter cruise phase, so very short flights often have a higher per-mile emissions factor than this average suggests.
Does cabin class affect emissions?
Yes significantly — business and first class seats take up more space per passenger, so the emissions attributed to each passenger in premium cabins are typically 2-4x higher than economy class for the same flight.
How can I offset flight emissions?
Many airlines and third-party services offer carbon offset purchases at checkout or separately, funding projects like reforestation or renewable energy — use a dedicated carbon offset cost calculator to estimate the price for your specific footprint.
