It follows the emergence of Twitter accounts such as @i fly Bernard and @laviondebernard that track the private jets of billionaires to expose the pollution they produce.

After being tracked by climate activists on Twitter, the second-wealthiest man in the world revealed he sold his private jet so “no one can see where I travel.”

According to Forbes’ real-time billionaire list, LVMH’s CEO, Bernard Arnault, has a net worth of $152 billion (£134 billion), overtaking Jeff Bezos of Amazon.

Twitter accounts such as @i fly Bernard and @laviondebernard were created to track Mr. Arnault’s and other billionaires’ private jets and expose the pollution they generate.

In fact, with all these stories, the company had a jet, and we sold it,” the 73-year-old French business billionaire told Radio Classique in France.

“As a result of renting planes when I utilize private flights, no one can observe where I travel.”

His 45-year-old son, Antoine Arnault, stated in the same interview that competitors could obtain vital information if others knew where the corporate jet was.

“It’s not a good thing that our opponents always know where we are,” he remarked.

This can provide ideas, as well as leads and hints.

On social media, Bernard Arnault is hardly the only public figure whose carbon footprint has been scrutinized.

A teenager created a Twitter account to track Elon Musk’s private jet last year.

The SpaceX and Tesla CEO portrayed the tracker, which uses public air-traffic data, as a potential threat to his safety and offered the teen $5,000 to delete the @ElonJet account, which was declined.

This year, a student from the University of Florida requested $50,000 from Mr. Musk, but the entrepreneur and the world’s richest man declined.
