ENR 2019 Top 200 Environmental Firms 1-100

 


August 2019

A strong economy in the U.S. and in some other key global markets pushed the ENR 2019 Top 200 Environmental Firms to revenue levels not seen for some years. Even with some exceptions, more public and private owners committed to big project investment and compliance steps to address both legacy and emerging environmental challenges. The Top 200 total environmental services revenue, based on what firms reported in 2018, hit $57.24 billion—up 7.3% from the previous year. Domestic revenue showed a 6% boost from last year’s total, with activity in global markets up 13.3%.

Please email ENRT200env@enr.com to be added to the Top 200 Environmental Firms email list for the 2020 survey filing, or to ask questions. The approximate Top 200 eligibility floor is $18 million in environmental services revenue for the prior year. The survey link will be emailed by the end of April.
