Best Environment Consultancy Services Companies in United States
The 701 best Environment Consultancy Services companies in United States in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: LSB Industries.
Sorting through 701 Environment Consultancy Services companies tracked across the United States by disclosed funding and recent momentum, this directory cuts straight to who's actually capitalized and moving. Total disclosed funding sits at $1.3B across the field, with 8 Rivers leading at $100M raised and Carbon A List close behind at $70M. No unicorns here, which I find telling: this is a sector built on contracts and regulatory mandates, not moonshot multiples.
The underlying market is real money. [Global environmental consultancy is a $68.8B market in 2024, forecast to reach $73.5B in 2025 at a 5.3% CAGR](https://thebusinessresearchcompany.com), driven by tightening environmental regulations and infrastructure buildout. So what separates the earners from the rest? Look at net income: Tetra Tech pulled $248M, roughly 447 times the sector median of $554,577. That's not a rounding error, that's structural scale. Headwaters sits at the other end of the funding table with $56,938 disclosed. The spread you're seeing reflects how fragmented this industry still is, with institutional backers like the National Science Foundation and the U.S. Department of Agriculture anchoring early-stage players rather than venture capital chasing exits.
