Partner Ranked on ENR's Top 200 Environmental Firms List for the 14th Consecutive Year

Partner climbs 25 spots as demand grows for environmental risk management across real estate, infrastructure, and remediation projects.

TORRANCE, Calif., Oct. 20, 2026 /PRNewswire/ -- Partner Engineering and Science, Inc. (Partner) moved up 25 places on Engineering News-Record's 2026 Top 200 Environmental Firms list, marking its 14th consecutive year of recognition on this list.

Based on 2025 revenue, the jump in Partner's ranking reflects strong demand for environmental consulting and due diligence services, driven by ongoing commercial real estate transactions, a growing need for programmatic environmental health and safety consulting, infrastructure investment, environmental remediation projects, and increasing regulatory requirements. Partner also continued to expand its expertise in building efficiency, resilience, and renewable energy.

Growth was supported by our integrated service model, which enables clients to efficiently manage environmental risk throughout the entire real estate lifecycle, from acquisition and development through remediation and asset management. Continued investment in specialized technical expertise, national coverage, and bundled service offerings strengthened our ability to deliver complex environmental solutions while maintaining the responsiveness and consistency our clients expect.

ENR's ranking covers environmental work in categories including:

• Hazardous and solid waste cleanup and management
• Nuclear waste cleanup and management
• Air pollution control, renewable energy, and energy efficiency
• Water supply and treatment
• Environmental management
• Environmental sciences and natural resources

According to ENR, environmental firms continued to find opportunities amid shifts in federal policy, supported by investment in domestic manufacturing, emerging contaminant cleanup, and AI infrastructure. Partner sees these trends reflected in growing demand for life sciences and pharmaceutical sector support, PFAS investigation, and data center feasibility and compliance consulting.

While elevated interest rates, economic uncertainty, and shifting commercial real estate investment patterns may affect transaction volumes going forward, these conditions also create opportunities for investment to improve the performance of owned real estate, including remediation, compliance, and asset repositioning services.

"The institutionalization of real estate combined with challenging market conditions is driving greater scrutiny and heightened due diligence on real estate investments," noted Kathryn Peacock, Strategic Director of Environmental Services for Partner. "At the same time, owners are shifting funds toward asset improvements, including tackling some of the environmental challenges they've been meaning to get to. Partner's tech-enabled approach helps clients streamline these efforts and gain efficiencies across capital planning and ongoing environmental obligations."

Growth was supported by our integrated service model, which enables clients to efficiently manage environmental risk throughout the entire real estate lifecycle, from acquisition and development through remediation and asset management.

Partner's international platform, broad technical expertise, and integrated service offerings position the firm well to capitalize on a shifting real estate market and emerging growth sectors, while continuing to deliver sustainable long-term growth.
