Greta Thunberg has revealed she has never had a drink and gives away the money she earns from being a climate activist.
The 19-year-old is best known for her environmental work which she began just as a teenager.
She has now opened up about not drinking alcohol.
Despite being in her teens, in an interview with The Times, Greta said that she had never been drunk before.
She said she would 'never go out drinking' and she would never do anything 'stupid'.
Trying to come up with a reason as to why this might be, she said: "I don’t know if that’s because I’m that kind of person or if it is because I don’t want to be 'seen'. I guess it could be both."
Greta also admitted that she does not earn any money from the work she does.
She said her only form of income is the student grant she receives for going to university.
She is set to publish a new book later this month that includes information from experts across the world on how we can tackle the climate crisis.
Her latest book, The Climate Book, that will be published in 15 different countries will earn her no money.
Greta said: "The proceeds that I will make will go to charity. It would be nice to have money, but by donating… For example, if I donate it to rewilding or nature conservation, I can start a debate on that. If I donate to refugees, you can talk about why – and then you can explain."
Greta said the only money she gets is a student grant, which she called 'not very sustainable'.
This interview comes after Greta made a surprise appearance at Glastonbury where she called out 'lying' political leaders.
She told festivalgoers that dishonesty in public office has not 'only become socially acceptable' but something the public now expects.
She appeared on the main Pyramid Stage this afternoon to share a short speech on the climate, telling crowds it will only get worse.
But, she insisted that 'we can still avoid the worse consequences' or climate change.
During her speech, Greta aid: "We are at the beginning of a climate and ecological emergency. This is not the new normal, this crisis will continue to get worse... until we prioritise people and planet over profits and greed."
She said 'we have been lied to, we have been deprived of our rights as democratic citizens and been left unaware' of the true scale of the climate crisis.
The Swede continued: "The forces of greed and profit and planetary destructions are so powerful that our fight for the natural world is limited to a desperate struggle to avoid a total natural catastrophe.
"We should be fighting for people and for nature, but instead we are fighting against those who are set on destroying it. Today our political leaders are allowed to say one thing then do the exact opposite."
