Beyond Greenwashing: McCormick Place's Verified Sustainability Milestone

CHICAGO, IL – June 08, 2026 – In an industry where 'sustainability' is often more of a marketing buzzword than a measurable practice, McCormick Place, North America's largest convention center, has just drawn a clear line in the sand. The sprawling Chicago campus has become the first facility in the world to achieve the Cleaning Industry Management Standard (CIMS) Green Building + Sustainability Certification with Honors from ISSA, the global association for the cleaning industry. This isn't just another plaque on the wall; it's a rigorously audited validation that sets a new, verifiable benchmark for what it means to operate a massive public venue responsibly.

A New Standard in a World of Green Claims

The push for sustainability has created a landscape rife with vague environmental claims and self-reported accolades. For corporate clients and event organizers trying to meet their own ESG (Environmental, Social, and Governance) goals, navigating this 'greenwashing' has become a significant challenge. ISSA's CIMS Sustainability certification aims to cut through that noise.

Unlike programs that might focus solely on using 'green' products, CIMS is a comprehensive management standard. It certifies the entire operational framework—the people, processes, and performance metrics that underpin a facility's cleaning program. The certification is built on five core pillars: Quality Systems, Service Delivery, Human Resources, Health and Safety, and Management Commitment. To achieve the advanced Sustainability designation, McCormick Place had to demonstrate excellence beyond these pillars, proving its commitment to environmental stewardship and green building practices.

The process is anything but a simple checklist. Certification requires a demanding on-site audit by an independent, accredited third-party assessor who verifies that documented procedures are being executed consistently and effectively. Earning the “With Honors” distinction is even more difficult, requiring the facility to meet 100% of the mandatory criteria and at least 85% of all recommended best practices—a level of excellence achieved by less than 10% of certified organizations. “McCormick Place’s achievement represents a defining moment for the meetings and events industry,” said ISSA Executive Director Kim Althoff. “As the first facility team to earn CIMS Sustainability Certification, McCormick Place demonstrates that sustainable cleaning and facility management is built on verified practices—not promises—and a model that other facilities can follow.”

The Operational Blueprint for Excellence

Achieving this milestone required a deep, campus-wide commitment, turning sustainability from a goal into a core operational principle. The certification is a testament to the close collaboration between the Metropolitan Pier and Exposition Authority (MPEA), which operates the venue, and their facility services partner, Aramark.

“This achievement would not have been possible without our strong collaboration with the Aramark team,” said Cullyn Doerfler, Senior Sustainability Manager at McCormick Place. “This certification reflects our campus-wide commitment to sustainability, from implementing green cleaning practices and environmentally responsible products to prioritizing the health, safety, and well-being of both frontline staff and campus visitors.”

This involved a granular focus on daily operations. According to Daniel Martinez, Aramark District Manager, the effort leveraged “training programs, rigorous safety protocols, and meticulous chemical and equipment tracking” that reflect industry-leading practices. For a 2.6-million-square-foot facility that welcomes three million visitors annually, this is no small feat. It means ensuring that every cleaning procedure, from the chemicals used in the vast exhibition halls to the training provided to every frontline worker, aligns with the highest standards of environmental and human safety. This integrated approach, which combines green cleaning protocols with robust infection prevention measures, creates a healthier indoor environment for everyone who walks through the doors.

“Earning CIMS Sustainability Certification demonstrates that MPEA | McCormick Place prioritizes sustainable cleaning and facility management practices and reflects our deep responsibility not only to our clients and partners, but to the broader industry,” said Larita Clark, Chief Executive Officer at MPEA.

The Economic Ripple Effect on the Events Industry

McCormick Place's certification is poised to send ripples across the entire business events ecosystem. As corporations face increasing pressure from investors and consumers to demonstrate tangible ESG progress, the sustainability credentials of their partners—including the venues that host their major events—are coming under intense scrutiny. “This moves the goalposts for everyone,” noted one industry consultant who advises corporations on event strategy. “A sustainability line item in an RFP just became a non-negotiable, verifiable benchmark.”

By securing this independent validation, McCormick Place gains a powerful competitive differentiator. It provides event organizers with credible, third-party proof that their chosen venue operates at the highest level of environmental stewardship, a claim they can confidently pass on to their own stakeholders and attendees. This is about building trust through transparency. The certification also has direct practical benefits, as the CIMS-GB framework is designed to help facilities earn up to 15 credits toward the prestigious LEED v5 O+M (Operations + Maintenance) green building rating system.

Perhaps the most potent endorsement comes from ISSA itself. Having experienced the venue's operational excellence firsthand during its own trade shows, the association is bringing its flagship ISSA Show North America back to McCormick Place in 2028. As Kim Althoff noted, “ISSA has hosted our ISSA Show North America Show at McCormick Place and experienced firsthand their commitment to best practices, sustainability, operational excellence, and accountability.” This decision signals deep confidence in the venue’s certified standards, acting as a powerful case study for the entire industry.

Deconstructing the Standard: More Than Just Green Cleaners

To fully appreciate the significance of the CIMS Sustainability certification, it’s useful to place it in the context of other well-known green building standards. While certifications like LEED (Leadership in Energy and Environmental Design) provide a holistic assessment of a building's environmental performance across its lifecycle, and the WELL Building Standard focuses on features that support human health and well-being, CIMS provides the critical operational component for both.

A building can be designed with the most advanced sustainable features, but if it’s not cleaned and maintained using best practices, its performance and health benefits can be compromised. CIMS ensures the 'how'—the management system that delivers a clean, healthy, and environmentally responsible indoor space day in and day out. It validates that the cleaning provider has the structure, training, and processes in place to support the building’s broader LEED or WELL objectives.

By focusing on the entire management system, CIMS Sustainability addresses the human element of facility operations in a way that building-centric standards do not. It ensures that staff are properly trained, safety is prioritized, and there is a culture of continuous improvement. This process-oriented approach provides a scalable and flexible framework that can be adapted to any facility, setting a universal standard for operational excellence.

For McCormick Place, this achievement is more than a single victory; it's the establishment of a new operating philosophy. By becoming the first to reach this summit, they have not only elevated their own standing but have also provided a detailed map for others to follow, transforming the abstract ideal of sustainability into a concrete, achievable, and verifiable reality for the global events industry.
