The Sustainable SITES Initiative is a rating system for landscape projects that focuses on project performance. It is a program similar to LEED Certification for exterior projects.

“SITES is a sustainability-focused framework that ushers landscape architects, engineers and others toward practices that protect ecosystems and enhance the mosaic of benefits they continuously provide our communities, such as climate regulation, carbon storage and flood mitigation. SITES is the culmination of years of research and development by leading professionals in the fields of soil, water, vegetation, materials and human health.”
