Every year, Earth Day is a reminder that sustainability isn’t optional; it’s a
responsibility. For the IREM Certified Sustainable Property (CSP) program, that responsibility translates into something even more meaningful to property owners: Measurable performance.
Earth Day is not just about awareness. It’s about action. And more importantly, results.
Turning sustainability into performance
The CSP program is built on a simple but powerful premise: Sustainability should deliver real, quantifiable outcomes. Properties that achieve CSP certification aren’t just “doing good;” they’re outperforming.
A look at CSP portfolio performance demonstrates how sustainability initiatives mean smarter, more resilient property performance. CSP-certified properties consistently outperform other properties in these areas:
-
Strong energy performance, with an average ENERGY STAR® score of 77
-
24% better emissions performance than the national median
-
32.5% better water use intensity than the national median
-
60% lower energy costs compared to the national median
These aren’t abstract goals. They’re operational improvements that impact asset value, tenant satisfaction, and long-term resilience.
As Brenton Neve, CPM®, chair of IREM’s Sustainability Advisory Council, puts it:
“Earth Day is a reminder that sustainability needs to move beyond intention to impact. The CSP program proves that when you apply the right strategies and data, sustainable practices don’t just benefit the environment, they strengthen property performance across the board.”
A tool for telling the story
To help members communicate this impact, IREM has developed the Environmental Stewardship infographic as a practical, data-backed storytelling tool.
Whether you’re speaking with clients, ownership groups, or internal stakeholders, this infographic makes it easy to demonstrate the business case for sustainability. It translates complex performance metrics into a clear, compelling narrative.
Expanding IREM’s sustainability ecosystem
This Earth Day also marks an exciting milestone: The introduction of IREM’s first Sustainability Advisor, RE Tech. The Sustainability Advisors program brings additional expertise and resources to members and CSP applicants looking to enhance building performance and navigate evolving sustainability standards.
It’s part of a broader commitment to equipping property professionals with the tools they need to lead.
Resources that drive action
IREM continues to invest in growing its sustainability resources to support members at every stage of their journey:
-
The Sustainability Hub: A centralized destination for tools, insights, and best practices
-
IREM Foundation Grants, like Elaina’s Sustainability Fund help organizations launch and scale sustainability initiatives
-
Education and professional development: Courses, Skill Badges, webinars, and on-demand content that turn knowledge into action
These resources help ensure that sustainability isn’t just aspirational, it’s achievable.
Earth Day is just the beginning
Earth Day may be one day on the calendar, but for IREM and CSP-certified properties, the work happens year-round. It’s embedded in operations, guided by data, and validated by results.
Sustainability is no longer a “nice to have.” It’s a performance driver, and the CSP program is proving it every day.
This Earth Day, take the opportunity to not only celebrate progress, but to share it. Use the CSP Environmental Stewardship infographic, engage with IREM’s resources, and continue pushing toward a more sustainable, high-performing future for the built environment.
