Langan rose eight positions to No. 65 in Engineering News-Record’s 2026 Top 200 Environmental Firms rankings, reflecting its position among companies providing environmental services to the construction and engineering sectors.
The annual rankings are based on firms’ environmental services revenue for 2025. ENR’s list examines several market segments, including hazardous waste, water and wastewater treatment, environmental management and environmental science.
The 2026 ranking report examines how demand for emerging contaminant cleanup, manufacturing and data centre development is influencing the environmental services market.
These areas involve environmental considerations that can affect site assessment, development planning and infrastructure delivery. As construction and industrial projects evolve, environmental consultants support clients in addressing site conditions and applicable environmental requirements.
Environmental services are an important component of construction and development, particularly where projects involve complex site conditions, water systems, contamination concerns or expanding industrial infrastructure.
Langan’s improved ranking provides an indication of its position in the environmental services market, although the announcement did not disclose the company’s specific 2025 environmental services revenue or the financial contribution of individual market segments.
