Why Join

Membership is open to all legal firms and affiliated organizations

Our diverse membership membership includes various types of law entities serving different markets and geographic locations. While many of our member firms are from the Am Law 100, we also embrace smaller, regional firms that are sustainability leaders in their own right. At LSN, we see all law firms and affiliated organizations as equals in the shared mission for greater sustainability across the industry. LSN offers a wealth of educational resources, including regular webinars where member firms share practical guidance on their experiences. Our collaborative platform enables firms to benefit from each other’s efforts, avoiding initial pitfalls and maximizing the effectiveness of their sustainability programs. Additionally, we maintain a library of member case studies, encouraging all members to contribute their valuable insights.

LSN membership is an annual subscription based on organization size. As of July 2024, membership tiers will be simplified as shown below. Membership subscription runs from June 1st – May 31.

Case Studies

We encourage each member organization to contribute a case study on any aspect of its environmental sustainability program within 12 months of joining. This has proven to be an invaluable means for our members to learn from each other’s experiences and help with the practical implementation of a wide range of initiatives.

Task Forces

We are re-establishing our task forces.  We ask that your firm participate in at least one of three committees.  These committees require a small time commitment of 1-2 hours every 3 months.

Our three committees include membership, partnerships, and communications.  If members would like to communicate on other topics, a new task force will be formed.

Knowledge Sharing & Eduction

Members discuss specific sustainability issues, share experiences, and help address similar concerns.

Member participate in educational sessions on sustainability issues, practices or new technologies with sustainability experts and leaders.

Case Study Library
Members record sustainability case studies and projects and have access to view other firm’s case studies.

Sustainability Resources
Members have access to an online knowledge bank of sustainability-related information, both to contribute to and to reference.
