About this data
Sources and processing
This data is based on the following sources
How we process data at Our World in Data
All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
Notes on our processing step for this indicator
-
CO₂ emission footprints do not necessarily reflect the amount of travel by locals in a given location. This is especially true if a country has high tourist volumes - much of the departures will result from travellers rather than local residents.
-
We have therefore also calculated 'adjusted' aviation footprints by multiplying international CO₂ emissions by an adjustment factor.
-
This adjustment factor is taken as the ratio between outbound and inbound tourist trips.
-
A high ratio of outbound-to-inbound tourist trips indicates that a country receives less visitors than its residents travel abroad. This results in a relatively lower burden of emissions from international flights being allocated to the country whose residents don't travel internationally as frequently.
