Our CO2 emissions calculations follow the International Air Transport Association (IATA) Recommended Practice - RP 1726 to calculate the estimated carbon emissions associated with a passenger's flying on a particular flight. The RP 1726 calculation methodology considers multiple parameters including aircraft fuel consumption, seat configuration, cabin class, aircraft type, and historical load factors from more than 400 airlines (precision of the calculation depends on the input data). You can learn more about these parameters and the calculation methodology here. The estimation results you see here are offered for informative reasons and do not precisely represent the emissions generated from your flying.

Carbon offsetting is a mechanism that enables individuals and organizations to advance climate action by supporting certified third-party projects that contribute to the reduction or removal of GHG emissions.

The Oxford Principles for Net Zero Aligned Carbon Offsetting (devised through collaboration with experts across the University of Oxford) define "Offset" as "Emissions reduction or removal resulting from an action outside of an organization's boundaries used to counterbalance the organization's residual emissions." You can learn more about this here.

Certified carbon projects issue carbon credits. Each carbon credit represents a single unit of GHG emissions (being one (1) tonne carbon dioxide equivalent (tCO2e)) that is reduced or removed from the atmosphere or the carbon cycle. A unit of GHG emissions can be reduced or removed through various methods or project types.

"Carbon offsetting" provides financing for these certified projects. The purchase of a "carbon offset" or carbon credit enables the buyer to contribute to these projects, and one often purchases "offsets" in an amount based on an estimated carbon footprint.

A carbon project's ability to issue carbon credits depends on a set of rigorous conditions – for a carbon project to issue carbon credits, the emission reductions or removals must be validated as additional, measurable, auditable, permanent, and unique.

In order for a carbon project to receive certification from a credible carbon certification body, it must demonstrate "additionality." Additionality means that the GHG emission reductions or removals associated with that particular project would not have taken place in the absence of the project and that the project would not have been financially feasible without the generation and sale of carbon credits.

All carbon offsets available on this platform are from certified projects, and so they have had the additionality criteria case checked by both an independent third-party verifier and the respective carbon certification body at project inception.
