Sustainable Leaders Network

What is the Sustainable Leaders Network (SLN)?

The SLN is a group of sustainability-minded students, faculty, and staff from each school or administrative department at Columbia University. From collaborating on user-friendly, campus-wide recycling bin signage to piloting innovative green solutions in their offices and classrooms, members of the SLN aim to drive behavior change from the ground up across Columbia's campuses.

In September 2016, when President Bollinger announced the creation of the University’s first set of Sustainability Principles, he introduced a new forum called the Sustainable Columbia Leaders Network (SLN). The provost also announced the creation of the SLN at the Council of Deans meeting held on September 8, 2016.

The deans of Columbia’s schools have identified three volunteers from each school to participate in this group: one faculty member, one student, and one administrator.

Members of the administration, faculty, and students have collaborated to generate this Sustainability Plan, the University’s first, complete with high-level goals. This Plan highlights a set of strategies that departments, including but not limited to Facilities and Operations, will advance over the next three years.

The role of school-based actions in the form of policy and behavior change accelerates the University’s ability to realize its sustainability goals. The primary objective of the SLN is to engage a wide range of stakeholders from across the campus to collaborate in developing and endorsing a set of these actions that can serve to guide Columbia’s schools to foster a culture of sustainability.

Once onboarded, SLN participants use the Workspace Certification tool to drive measurable culture change in their schools and/or departments. The experience gained will help other schools to utilize solutions and document progress.

Environmental Stewardship looks forward to sharing the progress Columbia is able to make over the course of the coming years through this energizing engagement platform.


If you are a Green Leader, login to Sustainable Columbia Workspaces and complete your self-audit.

In support of the University's Sustainability Principles, Columbia is committed to foster a culture of sustainability. The Workplace Certification webform provides a checklist of all the possible actions schools and departments can take at Columbia to support the University's sustainability goals as outlined in our plan.

Each section of the checklist links back to the corresponding pages of the Sustainability Plan for further reading. This allows participants to learn the reasons behind—and the impact of—each action, as well as how it relates to the overall vision for Sustainable Columbia.

These are required actions that must be completed as you begin the program.
