The Top 200 Environmental Firms

Text size: A A

Uncertainties in global markets and the unknowns of company participation combined to affect this year’s ENR Top 200 Environmental Firms survey results, with the list’s total revenue down by 4.3% to $51.4 billion, based on 2014 figures. The outcome reverses last year’s increase and continues an up-and-down trend in effect since 2008. Prior catalysts of surging oil markets and overseas growth both went into reverse, generating a 3.9% decline in domestic revenue for listed environmental services firms and a 7.6% falloff beyond U.S. borders—with Europe alone off 32.5%. But it was not all gloom and doom for the Top 200, with growth for a number of participants and sectors, and anticipation of marketplace improvement in the next 12-18 months.

The table below shows only rankings and company name. ** indicates that the firm did not appear on the 2014 list. For complete data from the 2015 Top 200 Environmental Firms report and to see prior lists (if you are an ENR subscriber), see the links below.

If you believe your firm could be ranked among the Top 200 in 2016, please send an email to ENRT200@construction.com to have your contact name and email added to the Top 200 list to receive our survey in April. We will send a link to the online survey, which is separate from ENR's Top 100-400-500 survey.
