Lewis Hamilton says he is not yet looking to leap into Formula E - even though he admits that could be a more "ethical" choice.
The six-time world champion has become outspoken on various progressive issues of the day, including climate change, sustainability and veganism.
And for that reason, he admits that Formula E - the all-electric series that races in city centres - is attractive.
But when asked if he is therefore eyeing the switch, Hamilton told the men's lifestyle magazine Square Mile: "The only reason that could be the case is for ethical reasons because sustainability is something I am very, very conscious of.
"And it's hard for me right now in wanting to be a part of positive change for our climate, yet you're flying everywhere."
But in terms of the actual racing, 35-year-old Hamilton said he is not ready to quit Formula 1.
"I race at the pinnacle of motorsport and in the foreseeable future Formula E is not going to be the pinnacle - and I want to be in the top echelon of the sport," said the Mercedes driver.
"For that reason, I don't envisage racing in Formula E, but I can imagine myself being a part of something in the background. I like the idea of what it stands for and what it's striving towards," Hamilton added.
