One long-distance flight consumes more fuel than a car uses for several years, and aircraft produce much more pollution than cars. Therefore, it would be better for the environment to discourage non-essential air travel – such as tourist travel – than to limit the use of cars. To what extent do you agree or disagree?
It is sometimes argued that curbing non-essential long-haul flights brings greater environmental benefits than restricting private car use, given the extremely high fuel consumption and pollution emissions of a single long-distance flight. While I accept that reducing unnecessary air travel can cut carbon output, I believe limiting car use is equally essential, and neither measure should be prioritized over the other for environmental protection.
On the one hand, discouraging leisure air travel does deliver immediate emission reductions. A 10-hour intercontinental flight can emit roughly 1 tonne of carbon dioxide per passenger, while an average private car emits around 4.6 tonnes of CO₂ over a whole year. For example, cutting just one round-trip long-haul holiday flight per traveller can reduce an individual’s annual carbon footprint far more than reducing car use for several months. This means policies targeting non-essential flights can achieve rapid, high-impact results for emission cuts with relatively less frequent travel behaviour change.
On the other hand, limiting car use addresses the far larger cumulative source of transport pollution. Globally, road transport accounts for roughly three-quarters of all transport-related greenhouse gas emissions, as billions of car journeys take place every single day worldwide, compared to a much smaller total number of long-haul flights. For instance, private car use for daily commutes in urban areas creates persistent, ground-level pollution that directly worsens urban air quality and public health, alongside its long-term carbon impact. Restricting car use through measures like congestion charges or expanding public transport also drives long-term, structural change to low-carbon travel systems.
In conclusion, I disagree with the view that discouraging non-essential air travel is better than limiting car use. Both measures are necessary, as they target different but equally damaging sources of transport pollution.
