How do you calculate my flight's carbon emissions?
Our carbon emissions calculations follow the International Air Transport Association (IATA) Recommended Practice - RP 1726 and take into account parameters such as all scheduled flights, aircraft fuel consumption and seat configuration, and historical load factors for more than 400 airlines. Precision of the calculation depends on the input data.

How do you calculate the carbon emissions related to my accommodation?
The Greenview Hotel Footprinting Tool is used to calculate the carbon footprint of hotel stays, which follows the methodology of the Hotel Carbon Measurement Initiative (HCMI). This tool uses data from the Cornell Hotel Sustainability Benchmarking (CHSB) Index, which includes information on energy, water, and carbon emissions from over 20,000 hotels worldwide provided by major hotel brands, operators, and owners from all regions of the world.

How do you calculate my carbon emissions from driving a car, taking the bus, or taking the train?
Carbon emissions are calculated using BEIS (UK Department for Business, Energy & Industrial Strategy) emissions factors, and are based on distance traveled.

Carbon offsetting enables individuals and organizations to take climate action by voluntarily supporting certified third-party projects that contribute to the reduction, avoidance, or removal of greenhouse gas (GHG) emissions.

Certified carbon projects issue carbon credits. Each carbon credit, carbon offset, or emission reduction unit represents a single unit of GHG emissions (being one (1) tonne carbon dioxide equivalent (tCO2e)) that is reduced, avoided, or removed from the atmosphere. A unit of GHG emissions can be reduced, avoided, or removed through various methods or project types (e.g. forestry projects, landfill methane recovery and destruction).

Carbon offsetting provides financing for these certified carbon projects. The purchase of a carbon offset or carbon credit enables the buyer to offset their GHG emissions by contributing to these projects that reduce, avoid, or remove GHG emissions elsewhere in the world.

A claim to have offset emissions is validated under a set of rigorous conditions—the emissions reductions, avoidances, or removals must be additional, measurable, auditable, permanent, and unique. The certification process for the carbon offset projects supported by this program is robust.

Yes. When you offset your carbon footprint, you'll support impactful reforestation projects, selected by CHOOOSE™ carbon professionals. Emission reductions enabled by project activities and certified to a credible carbon certification body must adhere to the principle of “additionality”—to be materialized and monetized as carbon offsets. This means that the projects are being implemented as a result of the (expected) proceeds from the sale of carbon offsets, enabling project developers to overcome the difficulties they face. In other words, you are not supporting a project that would have been carried out anyway. The additionality case is checked by third-party auditors and the respective carbon certification body at project inception.
