Meeting air quality and pollution targets is unusually difficult. There are two ways of doing that: reduce the numbers of travellers and/or improve the efficiency of the motive power concerned.
Reducing the number of people travelling by air, road, rail or sea is not going to happen, not unless the world population can be drastically reduced.
Increasing the efficiency of motive power is happening all the time, under continuous development and innovation. All engines are very much more cleaner, more powerful and use less fuel than in the past.
It is very easy to state "we should be flying LESS, not more", but until a remedy can be found that meets the reality of the situation then the status quo will continue. |
