Some celebrities are leaving behind a huge carbon footprint, and a newly released report has identified the big names who are the worst offenders.

A study released by marketing agency Yard, called out the celebrities who indulge in their luxurious lifestyles by frivolously flying their private jets. The biggest culprits of this non-essential, non-environmentally friendly form of travel are Taylor Swift, Floyd Mayweather and Jay-Z, to name a few.

Taylor Swift was reportedly the worst of the bunch, and had racked up “a total of 170 flights on her private jet since January,” according to Yard. They went on to report that Taylor has amassed a vast 22,923 minutes in the air.
