U.S. Environmental Consulting & Engineering Industry
EBJ C&E PRESS RELEASE
EBJ Report: After the U.S. Environmental Consulting & Engineering Industry Grew 10-11% in 2023 and 2024; the C&E Market ‘Normalizes’ to 6-7% in 2025–26, with Infrastructure, Energy & Data Center Drivers Ascendant
San Diego, CA — The Q4 2025 edition of Environmental Business Journal® (EBJ) released its, a 78-page analysis of the environmental industry. The opening section market review of EBJ’s Environmental Consulting & Engineering 2025, forecasts a post-boom “normalization” of the U.S. environmental consulting & engineering (C&E) industry and the forces reshaping growth, client & service portfolios, and consolidation.
Growth snapshot. EBJ’s annual C&E industry models, built on compiled revenues of more than 700 firms, show the U.S. C&E industry expanded 11% in 2023 and 10% in 2024 to $49 billion, then moderates to 6-7% in 2025 and 6-8% in 2026, a reset from the notable annual double-digit 2021–24 surge powered by infrastructure funding, PFAS, ESG, compliance, clean-energy programs, and a growing awareness of climate resilience.
The broader 14-segment U.S. environmental industry hit $573 billion revenues in 2025, with water, wastewater, and solid waste providing the steady “regulated base” of infrastructure, while clean energy, C&E, and water equipment have paced the upside during recent expansion phases. Most segments in services, equipment and resources are still above GDP in 2021–25, with only hazardous waste and some mature industrial services lagging.
What’s driving 2025–26. EBJ’s 2025 Outlook Survey ranks Domestic Energy Production as the #1 market driver, followed by Technology/AI investment and firms’ internal use of AI, with grid stabilization and distributed power rounding out the top tier. Federal agency spending is the only clear net drag as respondents report “policy whiplash” across many parts of the clean-energy value chain.
Market mix shift & AI. A boom-to-base transition in the environmental market means one-off surges of projects are being replaced with longer, programmatic pipelines of service contracts: PFAS work, for example, is evolving from emergency sampling into multi-year treatment design and utility capex in regulated state markets; higher rates have slowed marginal real-estate and merchant clean-energy projects, but rate-backed infrastructure remains resilient in its demands for C&E firms. Digital adoption—the application of AI across design, permitting, operations, and portfolio management—continues to shape productivity and service models, and is becoming a distinct business differentiator in the environmental services industry.
Consolidation at scale. EBJ’s business review documents the recent fourth and largest consolidation wave across the C&E industry: the number of U.S. firms with >$100M in environmental C&E rose to 80 in 2024, capturing 76% of market revenue, with average environmental revenue in these large firms climbing to $600 million. This “scale era” is propelled by global strategics and private-equity platforms buying specialized service or geographic capabilities across PFAS, resilience, energy transition, data centers, and permitting.
Historical context & cycles. From 1994–2026 EBJ identifies five distinct market cycles: a mid-90s maturation of an adolescent industry; the 2001–07 expansion; a 2008–10 economic crisis; the 2011–19 low-gear plateau; and in 2020–26, a COVID dip followed by the steepest run on record paced by infrastructure funding—then an emerging “new normal” of mid-single-digit annual growth with sharper variation by segment and business model.
EBJ analysis also tracks C&E revenue by major client sector (power, industrial, federal, state & local) and by U.S. region for 2018–24 that illustrates the rotation underway as utility, data center and mission-critical programs underpin 2025 project pipelines. Interestingly, in spite of Trump Administration anti-climate rhetoric many former government programs driven by ‘climate resilience’ have been rebranded as ‘mission-critical’ and remain on course, and private investment in climate risk management continues to grow across all asset-holding classes including banks and private equity firms.
About this edition. The opening 17 pages synthesize EBJ’s annual industry model, multi-survey outlooks, and consolidation analysis; subsequent sections feature executive Q&As, segment deep-dives, and data tables across key environmental markets.
