The Vatican, the smallest country in the world, is proving that size doesn’t matter when it comes to protecting the planet. In recent years, it has taken bold steps toward energy sustainability and is becoming a global example of environmental commitment.
It all began in 2008 when more than 2,400 solar panels were installed on the roof of the Paul VI Hall, the large auditorium where papal events and gatherings are held. Since then, the system has produced enough electricity to power the building’s heating, cooling, and lighting.
Pope Francis, known for his deep concern for the environment, wanted to take things even further. In June 2024, he signed an apostolic letter called Fratello Sole (Brother Sun), ordering the construction of an agrovoltaic plant in Santa Maria di Galeria, a Vatican-owned property just outside of Rome. This new project will combine solar energy production with agriculture, blending innovation and nature in a meaningful way.
The ultimate goal is to power the entire Vatican with 100 percent renewable energy. If successful, it would become the first country in the world to reach that milestone.
Through these efforts, the Vatican is not only reducing its carbon emissions but also sending a clear message to the rest of the world. Caring for our common home, as Pope Francis calls it, starts by setting an example for others to follow.
