A carbon footprint is a measure of the amount of carbon dioxide released into the atmosphere as a result of the activities of a particular individual or organization.

Each year, China Airlines uses carbon footprint calculation tools to analyze the carbon emissions generated by passenger/freight services. Not only does this serve as an important basis for corporate carbon reduction management, it also helps our customers understand the environmental impact of their flights.

By adopting the ICAO and IATA Carbon Emissions Calculator Methodology, we use actual flight fuel consumption, number of seats and passenger/cargo loadings to calculate your share of the flight’s emissions.



Note 1. We calculate the distance between airports using the ‘great circle distance’, which is the shortest distance between two points on the globe. Multiplying this distance by the carbon factor per km for your journey provides the total carbon footprinting

Note 2. Premier economy same as economy

There are no consistent aviation carbon footprint calculation standards in the world, so we chose to adopt the ICAO guidelines, as this is the closest measurement to an industry standard. Other airlines may also refer to ICAO guidelines. However, each airline has its own carbon emission calculation methods, including fuel emission coefficient, passenger/freight data range (calculated as the actual revenue portion or calculated in terms of maximum capacity), the passenger/freight data distribution and the flight distance, etc. On the other hand, the operational characteristics, type of aircraft used, type of passenger/freight services and cabin facilities might be different too. All the factors above may affect the calculation results, so it is not suitable for direct comparison.

No, it’s entirely voluntary. By calculating the climate impact from your flight and paying to reduce that impact you are choosing to take responsibility for those emissions. Please note that once you have completed the payment, no refund can be made.
