About Us

We believe by working collaboratively and giving legal professionals essential tools and resources, we can have a collective impact on preserving the environment. The LSN’s mission is to foster knowledge-sharing, develop best practice guidelines, and recognize innovation regarding environmental sustainability in the U.S. legal sector.

The LSN is a 501c3 nonprofit organization that was founded in August 2011 as an informal platform for law firm professionals to share ideas, network, and develop best practices and industry standards for sustainability throughout the legal profession. In 2024, the network was changed from Law Firm Sustainability Network to Legal Sustainability Network to be more inclusive across the legal industry. Grown out of the collaboration of nearly 50 firms, members bring a diversity of perspectives from various legal functions (such as legal practice and operations), and individual roles (including attorneys, C-suite officers, and administrative staff). Member firms, many of which are considered AM Law 100 or 200, also bring a broad range of expertise; participants from member firms have played key roles in the ABA, state, and local bar sustainability programs, heads of sustainability committees, environmental practice group leaders, and LEED-accredited professionals, among others.  The LSN has rapidly become recognized as one of the U.S. legal industry’s leading collaborative sustainability organizations.
