NGE Sets Global Net Zero Benchmark for Law Firms

CHICAGO, IL – April 01, 2026 – Chicago law firm Neal Gerber Eisenberg (NGE) has established a new global standard for sustainability in the legal sector, becoming the first law firm worldwide to achieve Certified Status for both Energy and Carbon under the Green Building Initiative’s (GBI) rigorous Journey to Net Zero program. The certification, awarded for the firm's three-floor office interior, signifies a verified 100% reduction in operational energy and carbon impacts, setting a precedent that moves beyond pledges to proven performance.

This landmark achievement is not just a win for the firm but a significant development for the professional services industry, demonstrating that deep, measurable decarbonization is attainable within leased commercial office spaces. It challenges the perception of what is possible for tenants and sets a new, verifiable benchmark in an era where corporate environmental claims are under increasing scrutiny.

Beyond Greenwashing: The Rigor of Verified Net Zero

At the heart of NGE's accomplishment is the GBI Journey to Net Zero for Sustainable Interiors program, an assessment designed to cut through aspirational claims with hard data. Unlike some green certifications that may rely heavily on design models or checklists, GBI’s program is performance-based, evaluating a project’s actual energy use intensity (EUI) and operational carbon emissions against stringent baseline standards.

To earn the dual Certified Status for Energy and Carbon, a project must demonstrate a 100% reduction in these impacts. This is accomplished through a combination of aggressive energy efficiency measures, strategic electrification to eliminate onsite fossil fuel use, and the procurement of verified renewable energy to cover all remaining electricity consumption. The certification is not a one-time award; it is valid for three years, requiring ongoing verification and encouraging continuous improvement, thereby ensuring long-term accountability.

This achievement builds upon NGE's existing sustainability credentials. The firm had previously earned LEED Platinum Certification for its new office build-out, making it the only law firm in Chicago with that distinction. While LEED Platinum is a prestigious and comprehensive standard, the GBI Journey to Net Zero certification specifically validates the ultimate goal of operational neutrality for energy and carbon, marking a distinct and advanced step in the firm's environmental leadership.

“Achieving Certified Status for both Energy and Carbon under GBI’s Journey to Net Zero program requires more than good intentions. It requires verified performance,” said Laci Hoskins, Principal at Novo Sustainability, the consulting firm that worked with NGE. “NGE’s certification reflects a high level of rigor, strong documentation, and a clear commitment to operating their space at a verified net zero energy and carbon level under the program’s standards.”

A Blueprint for Decarbonization

The path to this global first was not a singular project but the culmination of a long-term, integrated strategy. As highlighted by the firm's leadership, the certification is the result of years of deliberate choices woven into the fabric of the firm's operations and its physical space.

“This certification reflects years of intentional decisions rather than a single initiative,” said Sonia Menon, Chief Operating Officer of NGE. “From energy modeling and material selection to how we procure power and operate our space, sustainability is embedded into how our office functions every day. We’re proud to be the first law firm to meet GBI’s Energy and Carbon standards and hope it demonstrates what is possible for professional services firms committed to measurable, accountable progress.”

The process involved a holistic approach that began during the initial design of the office build-out. Key components included advanced energy modeling to optimize systems for efficiency, the selection of materials with lower embodied carbon, and the installation of all-electric systems to avoid direct emissions. The final, critical piece was securing verified renewable energy contracts to ensure that every kilowatt-hour of electricity used in the space is matched by clean energy generation, effectively neutralizing its carbon footprint.

The Strategic Advantage of Leading on ESG

While the environmental benefits are clear, NGE's investment in extreme sustainability is also a calculated business strategy. In today's market, a demonstrable commitment to Environmental, Social, and Governance (ESG) principles is a powerful competitive differentiator. For a firm that represents numerous Fortune 100 companies and leading private enterprises, aligning with the increasingly ambitious sustainability goals of its clients is not just beneficial, it is becoming essential.

This certification serves as a tangible answer to client due diligence questionnaires and an indicator of shared values. It positions NGE as a forward-thinking partner prepared for a future where supply chain emissions and corporate responsibility are paramount. Furthermore, such a commitment is a critical tool for attracting and retaining top legal talent, particularly among younger professionals who consistently prioritize purpose-driven and sustainable workplaces.

The firm's commitment extends beyond its office walls. NGE recently published a comprehensive Corporate Social Responsibility Report, detailing firm-wide initiatives in environmental stewardship, pro bono legal services, and community engagement, painting a picture of a sustainability ethos that permeates the entire organization.

Reshaping the Commercial Real Estate Landscape

Perhaps the most significant long-term impact of NGE's achievement will be its ripple effect across the commercial real estate market. As a tenant, the firm has powerfully demonstrated that occupants can be the primary drivers of decarbonization. This tenant-led initiative sends a clear signal to landlords and developers: the demand for high-performance, sustainable, and healthy buildings is growing, and tenants are willing to invest to make it happen.

With the built environment accounting for a substantial portion of global carbon emissions, the actions of commercial tenants are a critical lever for change. NGE's success provides a replicable model for other professional services firms and corporations, proving that net zero interiors are not a far-off dream but an achievable reality. This could accelerate a market transformation where landlords who invest in green building technologies and flexible, high-performance infrastructure will gain a significant competitive edge in attracting and retaining premium tenants.

By achieving this global first, Neal Gerber Eisenberg has not only transformed its own workspace but has also raised the bar for the entire legal industry, challenging peers to move from ambition to action and proving that a net zero future can start one office at a time.
