Here’s a funny truth: Greta Thunberg’s lifestyle is incredibly cheap. She doesn’t fly (big air travel costs zero dollars for her, because she refuses). She doesn’t buy new clothes—she wears second-hand, which means her wardrobe budget is basically the cost of a vintage T-shirt from a thrift store. She doesn’t eat beef or buy plastic water bottles.
Living like that, your biggest expense becomes “rent” and “oat milk.” She’s financially minimalist. It’s like that friend who only owns three plates and a single sweater but somehow seems richer than anyone else because they’re never stressed about bills.

The Foundation: A Fancy Piggy Bank
In 2026, Greta started a foundation called the Greta Thunberg Foundation. This is her official way of handling money. It’s a non-profit, meaning any donations she receives go into the foundation, are taxed properly (because accountants are heroes), and then are spent on climate initiatives. It’s like having a piggy bank, but the piggy bank is a legal entity, and the money pays for solar panels for Indigenous communities.
She also gets some speaker fees? Sort of. She’s been invited to high-profile events like the World Economic Forum in Davos. But she has a strict rule: she only accepts if the event is carbon neutral and if her travel is sustainable. And she often donates the fee. It’s like being paid to give a speech and then immediately handing the paycheck to the janitor.
