You attend meetings to network. At NAREIM, we honor the investment of your time by ensuring our networking, activities and content is focused on helping you build personal relationships with peers, who are facing the same challenges and opportunities as you. 

The NAREIM Sustainability meeting is just the place to build genuine relationships and friendships, where small group discussions and roundtable sessions provide not only detailed and relevant topics and education - but also networking opportunities with peers.


And of course, NAREIM is about candid conversations. You come to NAREIM to learn - and share. NAREIM is about the sharing of best practice ideas, solutions, challenges and opinions. It's a place to explore new ideas among peers and friends. That is no different in 2023.

As we work to develop our roundtable and group discussion content, we are committed to ensuring your time is well-spent. We invite you to come join fellow Sustainability peers in March. 

Attendance limits: Please note, owing to demand and space constraints, no more than two attendees will be allowed per investment manager member. We also ask that underwriting members send no more than one person.

Registration fee: $775
