ISI membership: Look who’s celebrating an anniversary

ISI is recognizing all organizations that have been with ISI for ten years, as of December 2023. The growth and development of the Envision framework and of the Envision Sustainability Professional (ENV SP)  credential would not have been possible without the steadfast support of the following public agencies and A/E/C companies. They’ve moved the needle for sustainability on infrastructure projects of all types, they’ve supported the development and use of Envision as a sustainability framework and planning tool, and many of them have significant cadres of staff who are active ENV SPs.

See our Envision Qualified Companies directory for information on the many Envision-rated projects these organizations have led. On the list of 10-year members, as well, are some long-time ISI/Envision public agencies such as New York City Department of Environmental Protection (NYCDEP), the Massachusetts Water Resources Authority (MWRA), Los Angeles County Public Works (LACPW) and the California Department of Water Resources (CDWR). Thank you for your continued support!

ISI is also giving special recognition to member organizations who are at the 5 year and 3 year mark with ISI as of December 2023. These are truly milestones worth celebrating, marking TEN YEARS of phenomenal growth for a sustainable infrastructure community powered by Envision®!
