The TIME honor came as Thunberg is in Madrid, Spain for COP 25. During a speech at the climate conference Wednesday, Thunberg said there is “hope” in the fight against the planetary emergency.

“But it does not come from the governments or corporations,” Thunberg said. “It comes from the people. The people who have been unaware but are now starting to wake up. And once we become aware, we change. People can change, people are ready for change…. Every great change throughout history has come from the people.”
