Many airlines, online booking sites, and standalone companies offer programs claiming to offset the greenhouse gas emissions of your flight with a small fee: usually less than $20.

In general, the way such programs work is that the carbon impact of a flight is calculated, and a fee is then determined that can “offset” this impact, minimizing or zeroing out the carbon imprint of a passenger's flight.
Why do airlines charge those fees? For starters, having an initial lower headline price makes air travel look cheaper, Keyes said. Airfares are taxed differently than fees. Plane tickets – and anything the ticket includes – are subject to a 7.5% excise tax, Keyes said, but that tax excludes optional fees.
Why some flights have lower emissions. Carbon emission estimates consider the origin, destination, aircraft type, and the number of seats in each seating class. Factors such as fuel-efficient aircraft and shorter routes usually result in lower carbon emissions.
