How carbon offsetting works
“Carbon offsetting” is a term used to describe a financing mechanism through which individuals and organisations can help support certified third-party projects by purchasing and “retiring” carbon credits. These certified projects contribute to the reduction or removal of greenhouse gas (GHG) emissions around the world. Support of these carbon projects has no direct effect on flight emissions or reducing flight emissions, but it does provide financial support that helps enable climate action.

What is a greenhouse gas emissions footprint?
A greenhouse gas emissions footprint, also informally referred to as a carbon footprint, is an estimation of all of the greenhouse gas (GHG) emissions that result from daily activities, transactions, or operations. GHG emissions trap heat in the atmosphere, and they include carbon dioxide, methane, nitrous oxide, and fluorinated gasses.
The provides guidance on how corporations should quantify and report on emissions. The GHG Protocol distinguishes between three different categories of emissions:
- Scope 1 emissions are from sources that are directly owned or operated by a company. These include emissions from manufacturing goods, combustion of fuels by company-owned vehicles or aircrafts, fugitive emissions, etc.
- Scope 2 emissions are from energy produced elsewhere and purchased to directly operate a company’s business. These include emissions from the purchase of electricity, steam, heating, and cooling.
- Scope 3 emissions are from activities associated with a company’s operations that are not directly owned by the company. In many industries, Scope 3 emissions account for the largest portion of a company’s greenhouse gas footprint. These include emissions associated with a company’s supply chains, business travel, employee commuting, leased assets, transportation, distribution, etc.
What is carbon offsetting? What are carbon offsets and carbon credits?
is a mechanism that advances climate action by supporting certified third-party projects that contribute to the reduction or removal of greenhouse gas (GHG) emissions.
Certified projects issue carbon credits, also referred to as offset credits or offsets, which act as an instrument for selling or trading the project’s associated removal or reduction impact. Each carbon credit represents a single unit of GHG emissions–one credit equates to one tonne of carbon dioxide equivalent (tCO₂e ) that is reduced or removed from the atmosphere or the emissions lifecycle. A key defining factor is that the emissions reduced or removed by a carbon credit would not have taken place without the prospect of selling such a credit. A unit of GHG emissions can be reduced or removed through various methods or project types.
A project's ability to issue carbon/offset credits depends on a set of rigorous conditions – in order for a project to issue credits, the emission reductions or removals must be validated as additional, measurable, auditable, permanent, and unique.
What does it mean to “retire” a carbon credit?
Certified projects issue carbon credits in an amount that is based on the tonnes of emissions that the project reduces or removes. Those issued credits are then tracked on a publicly available registry (e.g. Verra, Gold Standard, American Carbon Registry, etc.) When projects are certified by a recognized carbon standard, the credits are then issued on the registry of that standard. An individual credit can only be registered by one carbon standard. These issued credits can then be sold and traded. In almost all cases a credit is issued, it represents an amount of emissions that is already removed or reduced from the atmosphere, not a future facing action. This type of carbon credit is referred to as an ex-post credit and helps ensure the integrity of the purchase and the voluntary carbon market (VCM) at large. – for example, for corporate or individual offsetting.
The act of “retiring” a credit means indicating on the registry that the particular credit has been purchased and used. Once retired, a credit can no longer be sold or traded. This process avoids risks of double counting or double use of a given credit.
How are the offsetting projects or climate solutions vetted and selected?
SATA assesses every climate project we source through a three-step process informed by industry guidance. SATA’s overall approach aligns with best practices from the Integrity Council for the Voluntary Carbon Market, the Voluntary Carbon Markets Integrity Initiative, and the Oxford Offsetting Principles.
Building on this, we:
- Confirm the project is certified by a recognized carbon standard.
- Analyze quality against core criteria (How is the removed or reduced carbon quantified and monitored? How is the project additional? What is the track-record of the project developer? etc.)
- Compliment our internal analysis through leading external carbon offset evaluations.
How are emissions estimated?
Emission estimations follow the to calculate the estimated greenhouse emissions associated with a passenger's flying on a particular flight. The RP 1726 calculation methodology takes into account multiple parameters including aircraft fuel consumption, seat configuration, cabin class, aircraft type, and historical load factors from more than 400 airlines. Precision of the emissions calculation can vary based on the input data. You can learn more about these parameters and the calculation methodology .
These emissions estimates are provided for informative purposes only, and they do not reflect the actual emissions associated with your flight(s).

Our sustainability approach
Ensuring that we are doing what we are responsible for so that future generations can come to live in greater communion with nature and with the community in which they belong is a concern today and a project that has been implemented. It is a collective, continuous task, with no end in sight, which must constantly respond to new challenges. More than a project itself, it is a new way of being, in life and in business.
