The summer of 2023 was very significant for the travel industry. By the end of July, international tourist arrivals globally reached 84% of pre-pandemic levels. In some European countries, such as France, Denmark and Ireland, tourism demand even surpassed its pre-pandemic level.

This may be great news economically, but there’s concern that a return to the status quo is already showing dire environmental and social consequences.

The summer saw record-breaking heatwaves across many parts of the world. People were forced to flee wildfires in Greece and Hawaii, and extreme weather warnings were issued in many popular holiday destinations like Portugal, Spain and Turkey. Experts attributed these extreme conditions to climate change.
