Lighting the Way to Sustainability: A Materiality Assessment and Action Plan for the Leukemia and Lymphoma Society’s Light The Night Events

The Leukemia and Lymphoma Society (LLS) is a nonprofit organization with a mission to fund research for cures and treatments for blood-related cancer. Light The Night is one of the largest peer-to-peer (P2P) fundraising events, with approximately 1 million participants in 140 locations throughout the United States and Canada. Participants walk with illuminated lanterns to commemorate survivors, friends, family, and supporters. Sustainability has become a recent concern for the organization's corporate partners and participants. LLS has shown an increased dedication to sustainability by creating an Environmental Social Governance (ESG) council and has started taking steps toward creating a national plan for sustainability at its Light The Night events. In order to extend sustainability efforts to all Light The Night events, the client requests the Sustainable Light Knights team to: 1. Perform a materiality assessment for the Light The Night event, accounting for the recent changes that seek to minimize sustainability practices. 2. Rank the event's most material activities, considering food and beverage, waste, lanterns, and t-shirts. 3. Assess the best practices for managing the highest material impacts. 4. Identify short, medium, and long-term goals to help LLS plan for the next steps. The Sustainable Light Knights consist of four Arizona State University graduate students from the Masters of Sustainability Solutions program. The team undertook an analytical approach to understand P2P events, including conducting a landscape analysis, identifying best practices, and completing a TOWS (threats, opportunities, weaknesses, and strengths) analysis. This served as the foundation for the materiality assessment for Light The Night, which guided what impact topics were most relevant. To bring the findings of the materiality matrix to life, The Sustainable Light Knights created a sustainable event planning checklist, procurement guidelines, and a vendor pledge for use by Light The Night staff. We grouped the recommendations for sustainable actions into low, medium, and high priority and short, medium, and long-term goals. While this assessment focused on Light The Night, the recommendations outlined in this action plan can extend to other fundraising events organized by LLS. The design of the action plan is to help LLS leadership and staff take steps to lower the impact of Light The Night events nationwide and transform LLS into a leader within sustainable events that can serve as an example for other nonprofit organizations to follow.
