About ASLA

Founded in 1899, the American Society of Landscape Architects (ASLA) is the professional association for landscape architects in the United States, representing more than 15,000 members. The Society’s mission is to advance landscape architecture through advocacy, communication, education, and fellowship.

Sustainability has been part of ASLA’s mission since its founding and is an overarching value that informs all of the Society’s programs and operations. ASLA is a leader in demonstrating the benefits of green infrastructure and sustainable and climate-resilient landscape planning and design.

ASLA led the development of the ASLA Center for Landscape Architecture, its LEED Platinum headquarters, and green roof in Washington, D.C., and co-developed the Sustainable SITES Initiative (SITES) rating system. ASLA also develops and promotes publicly-accessible resources and news designed to educate members and the public about climate change, sustainability, and resilience.
