In the courtyard of the Onisifor Ghibu Theoretical High School in Cluj-Napoca, a small open-air amphitheater was built, with benches and planted trees, where students can have classes, read or conduct educational activities closer to nature. The space, called "green classroom", resulted from a partnership between the high school and a company from Cluj.

Mayor Emil Boc presented the project on Tuesday, September 29, 2026, on his Facebook page, calling it "a model of good practice" and "a classroom without walls". According to the mayor, the space is open to all members of the high school community, both for classes and for recreation during breaks or after school.

Boc expressed his wish for this model to be adopted by as many schools in Cluj-Napoca as possible and encouraged other companies to get involved in educational projects, saying that an investment in a school is actually an investment in a generation.
