How did we rank this year? See Roux’s ENR Rankings
Roux is excited to share this year’s ENR Rankings with our valued partners and staff. Engineering News-Record (ENR) provides vital data regarding the engineering and construction industry. Their annual list of the Top 200 Environmental Firms is based on prior year revenue reported from environmental services. Additionally, ENR publishes a “Top 30 All-Environmental Firms” List for firms reporting 100% of gross revenue in environmental services.
In 2026, Roux ranked #24 on the Top 30 List and #110 in the Top 200 List. We couldn’t achieve this without your support!
