Climate activist Greta Thunberg said Wednesday she's applied to trademark her name and that of the international school strike movement she inspired, a move meant to protect the movement from misuse for commercial purposes.

Axar.az reports that in an Instagram post, the 17-year-old Swede said that she and fellow activists have "absolutely no interests" in trademarks "but unfortunately it needs to be done."

Thunberg said the application covers her name, the name of the Fridays for Future movement, and "Skolstrejk för klimatet" (Swedish for "School strike for climate"), which was the slogan on a sign she held during the weekly solo protests outside Sweden's parliament that inspired similar actions by other young people.

Thunberg said that she and her family also are setting up a nonprofit foundation to transparently handle money from such things as book royalties, donations, and prizes.
