Green school concept in a school based on the teachings of the Catholic Church

Green schools, also known as eco-friendly schools or adiwiyata schools, focus on environmental awareness and sustainable practices. This research aims to provide a more in-depth understanding of the implementation and impact of green schools in schools. Adiwiyata schools encourage an active and sustainable environmental awareness movement. A unique aspect of this research is the exploration of Pope Francis' encyclical, Laudato Si, which highlights how schools, as part of the education system, contribute to the preservation and maintenance of God's creation. This research uses a qualitative approach with the theory of competitive advantage and refers to previous research related to green schools and adiwiyata schools. A green school implemented in a school that is systematically included in the school curriculum and run programmatically will make this school a school that has a competitive advantage. The character and culture of caring for the environment has been embedded in students and all school members, increasing the competitive advantage for schools that implement it. So that the sustainability of the school will occur along with the concept of hij au school applied in schools based on the teachings of the Catholic church.
