Kylie Jenner, Justin Bieber, Cristiano Ronaldo & More: The Top 10 Least Eco-Friendly Celebrities Ranked, According To Greens Steel

Reuseable drinkware brand Greens Steel analyzed the lifestyle habits of celebrities to see how green they really are. The company came to their conclusion by estimating how many cars, private jets, homes and overseas vacations they’ve taken since 2020. They also looked at these celeb's diets and their use of animal products.

"Celebrities are known for their love of long-haul flights, high-powered cars and wardrobes adorned with animal products. Looking over the data, it’s surprising to see Kourtney Kardashian, who prides herself as being one of the most environmentally-friendly and sustainably-conscious members of her family, in the top five least environmentally conscious celebrities," Abdullah Green, Founder of Greens Steel, said.

"These household names have an undeniable influence on society so while it is great to see some celebrities leading the way to a better world, there is definitely room for improvement for others. We hope these findings will shed light on the fact that although someone may claim to be 'environmentally friendly,' their actions really need to match their words and pledges. We hope to see more celebrities like Ariana Grande paving the way for a greener world," Green added.

Without further ado, here are Greens Steel's least eco-friendly celebrities.

OOPS! PRINCE HARRY AND MEGHAN MARKLE ARE THE LEAST ECO-FRIENDLY ROYALS

Cristiano Ronaldo is one of the world's most famous football players and seems to be the least eco-friendly celeb. According to Greens Steel, the 36-year-old has two private jets, six mega-mansions and 23 cars — including five Ferraris.

The youngest KarJenner appears to be the least eco-friendly of the family. Kylie Jenner came in second place on the list. This is due to her reportedly taking eight vacations on her private jet since 2020. She also has several cars, including a Rolls Royce, a Lamborghini and several Ferraris and Range Rovers. The makeup mogul owns five homes across California. Greens Steel found that Jenner eating meat and using animal products did not score her any eco-friendly points, either.

Coming in third place on Greens Steel's list is Kourtney Kardashian. Although the 42-year-old seems green due to her plant-based diet, she has reportedly taken six overseas vacations since 2020. While she doesn't have a private jet, she is said to have a collection of 25 cars, including a Ferrari and a Rolls Royce Wraith.

Justin Bieber came in fourth place on the list. This is due to the "Yummy" singer owning a private jet, 13 cars and three homes. He also reportedly took nine overseas vacations since 2020.

Dwayne "The Rock" Johnson came in fifth place on Greens Steel's list. The wrestler-turned-actor did not take any overseas vacations since 2020, but is said to have his own private jet. The 49-year-old reportedly owns 13 homes across the U.S. and in the U.K. He is also said to own a Rolls Royce Wraith, a Ford F-150 and a Pagani Huayra.

Kim Kardashian is the third KarJenner in Greens Steel's top ten. The 40-year-old does not own a private jet and eats a plant-based diet. However, she seems to have been brought down by her large car collection and five homes. She went on seven overseas vacations since 2020.

Lionel Messi came in seventh place on Greens Steel's list. The football player only took two overseas vacations since 2020, but owns 14 cars and a private jet. The 34-year-old also owns three homes; two in Barcelona and one in his home country of Argentina.

Kendall Jenner also joined her sisters on the least eco-friendly celebrities list. The model reportedly owns only one home and doesn't have a private jet. However, her collection of eight cars seems to have dragged her down when it comes to being green. She is said to have taken four overseas vacations since 2020.

Neymar is the fourth highest-paid athlete in the world, which may be why he owns 14 cars. The Brazilian football player is said to own two private jets and two homes.

Coming in tenth on Greens Steel's list is Jennifer Lopez. The actress is said to be on a plant-based diet, which may by why she is not higher on the list. However, the "Jenny From The Block" singer is believed to own six homes and seven cars. She has gone on three overseas vacations since 2020.
