HOW TO USE THE TABLES

Rankings: Companies are ranked below based on gross revenue they reported in 2007 for providing environmental services and products to domestic and international markets. The proportion of a firm’s gross environmental services revenue to its total gross revenue is provided as a percentage. Revenue figures are in $ millions. Percentages are rounded up or down to generate whole numbers.

Type of Firm: Designations are based on the largest proportion of environmental revenue reported by firms in seven categories: DES=Design, consulting and/or studies; CON=Construction and/or remediation; PM=Project and/or program management; EQP=Equipment and/or product manufacture; R&D=Technology and/or research & development; LAB=Laboratory and/or analytical services; OPS=Contract operations; OTH=Services not included in the above categories. Two or more designations appear if the largest proportion of revenue is evenly split between two or more categories, or if these categories are within 5% of each other. Companies not ranked among the Top 200 Environmental Firms in 2005 are designated by this symbol (**).

More detailed information on the Top 200 Environmental Firms can be found in the June 30/July 7, 2008 issue of ENR. Please click here for more information on ordering back issues.
