|Magnussen thinks F1 will eventually be forced to go 100% electric, but it cannot as Formula E has that FIA charter|
(GMM) Kevin Magnussen thinks environmental concerns are the "biggest threat" to Formula 1.
After Lewis Hamilton faced backlash for promoting his 'green' credentials, Haas driver Magnussen revealed that he too has become a vegan.
"There is no doubt that the meat industry accounts for a significant portion of the total CO2 emissions," he said.
Magnussen also told the Danish newspaper BT: "It is clear that there is a serious problem with the climate and I cannot understand if anyone denies it."
Magnussen, 27, also acknowledged the hypocrisy of F1 drivers crowing about the environment.
"I'm a Formula 1 driver and I fly around the world, but at least I've started to have a bad conscience about it," he said.
"I have recognized that there is a problem and I am keen to see how Formula 1 will respond.
"It's not an easy sport to turn green, but it is the biggest threat Formula 1 faces," Magnussen added.
