The 2016 Top 200 Environmental Firms 1-100
August 2016
A government change that began to unfold last year in the U.S., and economic and political turmoil elsewhere,did not curb spending on environmental needspushed by global demographic trends and natural events. Even with budget constraints and delayed contracting, ENR’s Top 200 Environmental Firms saw their revenue grow 3.8% in 2015 to $53.4 billion. The strength of the American economy was evident,as U.S.-generated revenue rose 10.7% to $41.4 billion—over the $40 billion mark for the first time in four years—but revenue beyond its borders fell by the same proportion, to $11.86 billion. Environmental regulation will continue to drive new work, say participants.
