Flights: GHG (greenhouse gas) emissions

Our emissions scoring reflects the impact of your flight by comparing your total emissions to the daily average emissions per person in your country. We also convert the total GHG emissions into a cost using the carbon price specific to your country. This approach provides a clearer sense of the environmental and economic impact of your flight relative to local standards.

Our methodology adheres to Bilan Carbone and ISO14064 standards, focusing primarily on the significant source of GHG emissions during flights: fuel combustion. We calculate fuel-related emissions using guidelines from the International Civil Aviation Organization (ICAO) and the UK’s Department for Environment, Food and Rural Affairs (DEFRA), considering factors like aircraft type, load, and flight distance. Although fuel is the main contributor, we also include emissions from waste disposal and in-flight food and beverage consumption to provide a comprehensive assessment of the overall environmental impact of air travel.

Airline's Environmental Efforts

Our scoring reflects the airline's efforts to reduce emissions. We consider measures such as the use of Sustainable Aviation Fuels (SAF), which play a crucial role in lowering aviation-related carbon emissions. By factoring in these initiatives, our approach recognizes airlines that actively invest in sustainable practices.



Planet Resources

Waste Management

One often overlooked impact of air travel is waste production, including cabin waste, maintenance by-products, and hazardous materials.

This part of the score depends on the airlines used during the flight. We take into account the annual amounts of hazardous and non-hazardous waste produced, waste reduction goals of the airline and their recycling policy.



Respect Communities

Noise Reduction

Another significant impact of air travel is noise pollution from aircraft, which can affect communities near airports and disrupt local wildlife. Including noise pollution in our scoring is important as it recognizes the broader environmental consequences of air travel and encourages airlines to adopt quieter technologies and operational practices.

We evaluate the compliance of the airline with international standards and regulations, as well as their initiatives to reduce noise (partnership with local communities, adapted fleet, night flights restrictions,...).
