For Princeton Junior School, "being green" means to educate children and the wider Princeton Junior School community about environmental sustainability, to strive for efficient use of resources and energy, and to provide a healthy indoor and outdoor school environment. In spring 2007, a Green Committee was founded with faculty, staff and parent members. The Green Committee reviews common practices in the school and supports changes towards greener alternatives. For example, electronic communications and double-sided photocopying are promoted to reduce paper use. All classrooms and common areas have recycling buckets. Children, teachers, and staff are encouraged to reduce waste by preparing “waste-free” lunches and by using reusable containers or mugs for drinks. Cleaning products have been replaced by more environmentally friendly products. Energy usage is monitored and improvements are made when possible.
