Celebrities use private jets excessively. It’s a climate nightmare.

Popular celebrities are no strangers to being at the top of rankings. But several big names recently found themselves featured on a new list: “Celebs with the Worst Private Jet Co2 Emissions.”

The analysis of flight data, which was published online Friday by a U.K.-based sustainability marketing agency Yard, came on the heels of other celebrities such as Kylie Jenner and Drake weathering intense public criticism after it was revealed that their emissions-spewing private jets logged trips as short as 17 minutes and 14 minutes, respectively.

Using data from a popular Twitter account that tracks celebrity jet movements based on public information, the report stated that planes affiliated with celebrities emitted an average of more than 3,376 metric tons of CO2 — roughly 480 times more than an average person’s annual emissions. The report, which was not peer-reviewed and features a prominent disclaimer about its analysis, includes the names of a handful of celebrities, at least two of whom have publicly disputed the list, saying that the flight data affiliated with them does not reflect their actual usage.
