Wealthy frequent flyers who take several holidays a year should pay higher taxes each time they fly, a British charity says.

Although low-cost high-volume air travel has grown hugely this century, only a small proportion of the population, mostly in the world’s richest countries, ever take a flight – the frequent flyers who can afford to do so.

It is estimated that less than 20% of the world’s population has set foot on a plane, and of those that do fly, most travel by air once a year or less often, while the richest few take several flights annually.

This matters, because aviation is a significant driver of climate change,  and to prevent the world overheating dangerously pollution from aircraft has to be curbed.

One suggestion is that people who take many flights should pay a rising tax. Everyone’s first flight would be tax-free, to protect people taking one holiday a year, but frequent flyers, many of whom take a series of holidays, would pay an increasing tax for each extra flight in any calendar year.
