Portugal is now asking all passengers “for the climate” to pay two euros. The country introduced what is known as a carbon dioxide tax. This must be paid by all departing passengers and must be collected by the airlines when booking the flight.

The introduction of such a tax has been discussed for a long time, but the introduction took place almost silently on July 1, 2021. Tickets booked before this date are excluded. Regardless of the flight duration, two euros are to be paid. "Collection" is carried out by the airlines, who have to make the payment on the fifth of the following month. A report must also be submitted to the aviation authority.

What exactly happens to the tax revenue is not so transparent. Although it is said that this should be invested in climate-friendly mobility, that is a rather vague term. While the new fee will hardly be noticed on long-haul flights, Ryanair tickets, which are often offered in the single-digit euro range, could well become more expensive.
