ENR 2024 Top 200 Environmental Firms
Financial, legal and political bumps did not dent the global environmental services market for ENR’s Top 200 Environmental Firms, based on results reported in this year’s ranking. Ramped-up project spending to address climate change and energy transition urgency, and new infrastructure needs, triggered a list revenue surge—buoyed by company mergers and acquisitions to build workforce size, bottom line strength and technical capacity to execute the growing mission. Top 200 firm executives are closely watching how—or whether—the upcoming U.S. elections and new global tensions will alter market trajectory, but most are hopeful that other forces will sustain it.
Please email ENRT200env@enr.com to be added to the Top 200 Environmental Firms email list for the 2025 survey filing, or to ask questions. The approximate Top 200 eligibility floor is $20 million in environmental services revenue for the prior year. Please don’t file if your total is below that figure.
