American Society of Landscape Architects

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 has been a leader in demonstrating the benefits of green infrastructure and resilient development practices through the creation of its own green roof, co-development of the SITES® Rating System, and the creation of publicly-accessible sustainable design resources.

Standards of Conduct

ASLA is committed to providing a safe, productive, and welcoming environment that fosters respect, fairness, and integrity for all whom participate in the ASLA Annual Conference on Landscape Architecture. ASLA members and guests should maintain the highest standards of personal conduct, refrain from engaging in discrimination or harassment, and abide by the meeting safety and responsibility policies.

Leave No Footprint Behind

ASLA continues efforts to reduce the carbon footprint of the conference. Our organizational partners, product suppliers, and venues play an important role in this effort. They work with us to ensure that all print materials, signage, decorations, and equipment are recycled and/or recyclable, almost all handouts are distributed electronically. We, together are thoughtful in our approach and are committed to implementing sustainable practices at the conference and in our workplaces.

The San Diego Convention Center supports and encourages sustainable practices in its LEED Gold certified building and has won dozens of state and city awards for its eco-conscious initiatives throughout the years. In 2018 alone, 57 percent of generated waste was diverted from landfills; 125 tons of non-edible food was composted; 72 tons of edible food was donated to the San Diego Rescue Mission, enough to plate 115,000 meals. The conference headquarters hotel is equally committed to sustainable practices by the U.S. Department of Energy for Platinum Superior Energy Performance, among other awards by the city and state.

The hotels chosen as official hotels were selected in part because of their commitment and accolades for their sustainability efforts. Separately, one of ASLA’s most valued contributions to sustainability is that of our exhibitors. At the close of the conference, exhibitors donate booth products toward building a project in the San Diego community. The ASLA/ACE Legacy Project is a collaboration between the ASLA Host chapter and the ACE Mentor Project, our generous conference exhibitors, and the ongoing commitment and support of Freeman Expositions.
