The 2015 Top 200 Environmental Firms 1-100

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.
