Cars and planes are two of the most common forms of transport, but which is worse for the environment? Both have a significant impact on the planet, but in different ways. Planes emit more CO2 per capita, but they carry more people and are faster. Cars, on the other hand, are more numerous and emit more CO2 per kilometre. So, which is the bigger evil?
Characteristics | Values |
---|---|
CO2 emissions per km | A 747 emits 115g of CO2 per passenger per km, while the average passenger car emits 0.132 kg of CO2 per km |
Total emissions | Planes have larger total emissions |
Impact | Plane pollution has a greater impact because it's higher in the atmosphere |
Passenger capacity | Planes carry more passengers than cars |
What You'll Learn
Cars emit more CO2 per kilometre than planes
Although planes are a very polluting and problematic means of transport, cars emit more CO2 per kilometre. A 747 emits 115g of CO2 per passenger per km, while the average passenger car emits 0.132 kilograms of CO2 / kilometre. This means that cars are slightly more polluting than planes.
However, it is important to note that planes' pollution has a greater impact because it is higher in the atmosphere. Additionally, planes typically carry more passengers than cars, so the per-capita emissions of planes are lower than those of cars.
Recent studies generally agree that a plane isn't necessarily the most polluting means of transportation. In fact, a car often pollutes just as much, if not more, than a plane over equivalent distances. This is because cars typically only carry 1-2 people at a time, while airlines try to fill as many people as possible to maximise profits.
Despite this, it is worth considering the impact of both cars and planes on the environment. Both modes of transport contribute significantly to pollution and have their own unique set of advantages and disadvantages.

Recent studies generally agree that a plane isn't necessarily the most polluting means of transportation. In fact, a car often pollutes just as much, and sometimes even more than a plane over equivalent distances. This is because cars typically only carry 1-2 people at a time, while planes are packed with as many passengers as possible to maximise profits.
However, it's important to note that plane pollution has a greater environmental impact because it's released higher in the atmosphere. Additionally, planes remain a very polluting and problematic means of transport, even if the total emissions per km are lower.
Overall, while planes may emit less CO2 per km than cars, they typically carry more passengers, resulting in higher overall emissions per person. This, combined with the higher atmospheric release of emissions, makes planes a significant contributor to pollution.

Cars carry fewer people
Planes are also faster and less accident-prone than cars, which can make them a more attractive option for long-distance travel. For example, someone living in Ireland who wants to visit family in the Netherlands would have to take a boat, which would take much longer than flying.
However, it is important to note that planes are a very polluting means of transport. While a plane emits 115g of CO2 per passenger per km, a car emits 0.132 kilograms of CO2 per km. This means that, per capita, a plane pollutes more than a car.
Despite this, it is difficult to compare the two modes of transport directly. This is because the amount of pollution emitted by a plane depends on the type of plane chosen as the "average" plane. Additionally, the pollution from planes has a greater impact because it is released higher in the atmosphere.

Planes are faster
Planes are also able to carry more people than cars, which can further reduce the amount of CO2 emitted per person. For example, a plane might carry 300 passengers, while a car typically only carries 1-2 people. This means that, in terms of CO2 emissions per person, planes can be more efficient than cars.
Additionally, planes are less accident-prone than cars, which can also reduce their overall impact on the environment. For example, a plane crash is much less likely to occur than a car accident, and the environmental impact of a plane crash is typically much lower than that of a car accident.
Overall, while planes may emit more CO2 overall, when considering the number of people they carry and their speed and safety advantages, they can be considered a more efficient and less polluting means of transportation than cars.

Planes are less accident prone
Planes are also more efficient in terms of the number of people they can carry. While most cars only carry 1-2 people at a time, planes can carry hundreds of passengers. This means that the pollution emitted per person can be lower for planes than for cars. For example, a 747 emits 115g of CO2 per passenger per km, while the average passenger car emits 0.132 kilograms of CO2 per km.
However, it is important to note that the pollution from planes has a greater impact because it is released higher in the atmosphere. This means that the pollution from planes can have a more significant impact on climate change.
Overall, while planes may be less accident-prone, it is important to consider the environmental impact of air travel. Recent studies seem to generally agree that a plane isn’t necessarily the most polluting means of transportation. That’s why it’s also being said a car pollutes just as much, and often even more than a plane over equivalent distances.
