ISI Honors 5-Year Members

To help communities and organizations navigate the complexities of sustainability, resiliency, and equity, ISI embraces strong partnerships and purposeful models of cooperation and collaboration with our member organizations. No single entity or organization has the capacity to act alone, which is why we value consensus building and meaningful relationships. The following is a list of companies, public agencies, and academic institutions celebrating 5 years of membership with ISI.

In total, ISI is honoring nearly 50 accounts who have been members through June 30, 2020.

As you will see below, hundreds of Envision Sustainability Professionals (ENV SPs) are employed by these member organizations. ISI would like to personally thank each organization and its ENV SPs for their commitments to Envision and to sustainability.

If you have any questions about membership or would like to join, please contact ISI’s Membership Director, Audrey Gorham, or ISI’s President and CEO, Anthony Kane.
