The purpose of the Green Schools Initiative is to reduce the consumption of natural resources, and embed environmental responsibility in the culture of OPS. To date, 100% of the schools/programs and administrative offices participate. Students collect recycling, serve as energy managers, pick up litter, plant trees, and participate in related community events.  After four years, OPS has seen a positive culture change, has dramatically reduced it environmental impact, and has accumulated approximately $5.3 million in cumulative cost reduction and avoidance.
