Portfolio of climate projects
Your voluntary contribution goes directly towards verified carbon offset credits from a portfolio of climate projects. These projects provide environmental benefits and generate positive socio-economic outcomes for local communities. Each project is independently verified according to international standards, ensuring real and measurable impact. While purchasing offset credits does not directly reduce emissions from air travel in the aviation sector, your contribution towards carbon offsetting projects can be viewed as supplementary action that complements broader decarbonisation efforts and supports much needed climate action around the world.

Frequently Asked Questions
Carbon offsetting and carbon credits
What is Carbon Offsetting?
Carbon offsetting is a mechanism that supports 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 role does carbon offsetting play in tackling climate change?
Addressing climate change at scale requires concerted action to prevent new greenhouse gas emissions and to reduce or remove existing emissions from the atmosphere. Carbon offsetting is one way to facilitate the sale of carbon credits, which in turn enables the financing of projects that carry out emissions reductions or removal activities. Carbon offsetting is not intended to replace a company’s or individual’s efforts to reduce their emissions footprint. Emissions reduction is paramount to limiting the effects of climate change. Instead, carbon offsetting should be viewed as supplementary to broader decarbonisation efforts and climate action around the world.
How are offsets verified?
The offsets made available through this programme are from projects that are certified by internationally recognised carbon certification standards. Each of these certification standards sets requirements for the design, implementation, and execution of a given project. Accredited, independent, third-party verifiers then assess the carbon credits a project proposes to issue based on industry best practices as well as the verification criteria indicated in each specific standard.
How is carbon offsetting under SIA Group Voluntary Carbon Offset Programme different from CORSIA?
CORSIA is the first global market-based measure developed for the aviation sector to offset residual carbon emissions that cannot be directly reduced through technological and operational improvements, as well as alternative low-carbon fuels. In order to meet ICAO’s aspirational goal of carbon neutral growth from 2020, ICAO sets strict criteria for which carbon offset project development programmes are eligible for compliance under CORSIA. The SIA Group supports and complies with longer-term international obligations under CORSIA to reduce emissions from international aviation. The SIA Group manages all compliance requirements under CORSIA at our own cost and your contribution will not help the SIA Group reach its CORSIA obligations.
How we estimate emissions
How do we estimate emissions?
Emission estimations follow the to calculate the estimated greenhouse emissions associated with a passenger's travel. 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. Emissions calculations will vary based on input data. These estimates are provided for informative purposes only, and they do not reflect the actual emissions associated with your flight(s).
Is the carbon footprint different for different cabin classes?
Yes. The seats in each cabin class take up different amounts of space and weight on the aircraft. As different cabin classes have varying impacts, we have factored this into our calculations in accordance with international standards.
Your contribution
Will purchasing carbon offsets or carbon credits create environmental impact?
By purchasing carbon credits, you support climate solutions such as nature-based solutions, renewable energy projects, or community projects that reduce or remove greenhouse gas emissions. In a hard-to-abate aviation sector where decarbonisation levers remain limited today, carbon offsetting helps to address residual emissions that cannot be removed based on existing technology and emission reduction efforts. Purchase of offset credits does not directly reduce emissions from air travel, but your contribution towards carbon offsetting projects supports broader decarbonisation efforts and climate action around the world.
How do I know that the impact would not have occurred without my support?
In order for a climate project to receive certification from a certification body, it must demonstrate "additionality." Additionality means that the GHG emission reductions or removals associated with a particular project would not have taken place in the absence of the project’s existence. It also means that the project would not have been financially feasible without the generation and sale of carbon offsets/credits. All carbon offsets available on this platform are from certified projects. They have had the additionality criteria case checked by both an independent third-party verifier and the respective carbon certification body at project inception.
Do I get a refund if I cancel my booking?
Purchasing a carbon offset is a voluntary contribution to a verified carbon offset project. Therefore, if a customer pays for an offset but does not travel, no refund will be provided.
Does the SIA Group profit from this programme?
No. The SIA Group does not profit from the sale of carbon offsets purchased under the carbon offset programme. All voluntary contributions made by customers are directly channelled to Chooose to source verified carbon offsets from projects worldwide.
