Facts about pollution from aviation emissions
01
Background
Background
Aviation accounts for around 2.5% of global CO² emissions, but 3.5% when we take non-CO² impacts on climate into account. Air travel dominates a frequent traveller’s individual contribution to climate change. Yet aviation overall accounts for only 2.5% of global carbon dioxide (CO2) emissions. This is because there are large inequalities in how much people fly – many do not, or cannot afford to, fly at all.
Non-CO2 climate impacts mean aviation accounts for 3.5% of global warming
Aviation accounts for around 2.5% of global CO2 emissions, but it’s overall contribution to climate change is higher. This is because air travel does not only emit CO2: it affects the climate in a number of more complex ways.
As well as emitting CO2 from burning fuel, planes affect the concentration of other gases and pollutants in the atmosphere. They result in a short-term increase, but long-term decrease in ozone (O3); a decrease in methane (CH4); emissions of water vapour; soot; sulfur aerosols; and water contrails. While some of these impacts result in warming, others induce a cooling effect. Overall, the warming effect is stronger.

There is no global reliable figure, but often cited estimates suggest that more than 80% of the global population have never flown.
A plane’s take-off and landing can cause serious air pollution. The problem is that ordinary people travel with many other people on a plane, so when they calculate their carbon footprint, they divide the emissions from the plane by the number of people traveling with them. In contrast, private jets are different. Based on this calculation, one trip on a private jet emits the same amount of emissions as several hundred. Moreover, most people who travel by plane live in wealthy countries. Even if ordinary people are environmentally friendly for a lifetime, the result may not be as much as if a rich person flew on a private jet once.
The 80% of people who have never flown need to pay for civilian, private, transport and fighter aircrafts.

Data Analysis
Data Analysis
Conducted by IEA
Survey period：2000 to 2021
Region：Worldwide
Carbon dioxide (CO₂) direct emissions from the aviation sector worldwide from 2000 to 2021, by flight type (in million metric tons)
This set of data is for the timeline and it will be used as the source data for the introductory visualisation of this project. It will present the CO2 emissions from aviation from 2000 to 2021, and one will learn from this data set that air pollution from aviation is rising every year.
International and domestic per capita CO2 emissions due to aviation in 2018
This is the data presented for the map, which is intended to support the idea that 20 per cent of the population is responsible for all aviation emissions, and it is clear that some impression is that richer countries are responsible for more aviation emissions.
International and domestic per capita CO2 emissions due to aviation in 2018
This data set is primarily used to compare the fuel usage of private and civil aircraft. I collected the common private and civil aircraft models, fuel usage (regardless of the process of take-off, landing, etc.) and maximum passenger capacity, and from these I calculated how much fuel each would use on average.
