Partner is proud to be featured on the ENR Top 200 Environmental Firms list for the fifth straight year. This year, we are delighted to sit among the list’s biggest climbers, moving up the list an impressive 12 places to #114. Partner is recognized for delivering reliable Phase I ESA reports as part of comprehensive environmental due diligence.
The environmental firms making up this year’s list held their own, despite priority shifts resulting from the election of the new President, an uncertain post-Brexit Europe, and still-sluggish oil.
In their announcement of the list, ENR reported that the market for environmental services is enjoying steady growth. This comes despite the conventional wisdom suggesting that policy shifts and compliance reversals should greatly reduce or even eliminate the need for services. Instead, the continued growth proves that corporate clients are more likely to avoid large procedural swings in business operations by continuing to invest time and money to meet the more stringent environmental standards developed under the Obama Administration.
List participants in their overall revenue last year managed a 2% hike to $54.47 billion—a total not seen in five years. More on the full list can be found here.
