Founded in 1999, the Maryland Green Schools Program (MDGS) is a sustainable school program that is nationally recognized as having a significant impact on students and schools. The program is aligned with the goals of the 2014 Chesapeake Bay Watershed Agreement and supports Maryland State Department of Education graduation requirements and standards.

This program provides PreK to 12th-grade students with educational opportunities that empower them to make changes to reduce environmental impact, practice environmental stewardship, encourage sustainability, increase awareness of how our relationship with the environment ultimately impacts public health and society and fosters environmental literacy.

There are currently 664 Maryland Green Schools. This is 33% of approximately 2,200 public and independent schools and there are approximately 430,000 PreK to 12th-grade students attending these schools. Green School communities represent a significant opportunity to maintain and improve environmental sustainability, with over 125 million square feet of building space and grounds covering thousands of acres.

Maryland Green Schools benefit from the instructional support and partnership of Green Centers and Green Leaders. Green Schools have access to an extensive network of partners in their community and statewide resources.
