Our clients are the lifeblood of Ecos and we believe in developing with them a real partnership.
Here’s what a few of them have to say about Ecos.

“I could not have been more satisfied with the work Ecos performed. Not only did they do what I had expected in creating an exhaustive analysis of the Park's environmental efforts and an inventory of greenhouse gas emissions created by Park operations, but they went on to create a list of over 60 specific projects which the Park could undertake to reach a clearly articulated environmental goal by the year 2016. This list provided not only an estimate of cost for each project but a clear statement of how each project contributed to the overall goal. What was most impressive and unexpected was a coherent management plan for the Park for how to put procedures in place to ensure that the environmental stewardship to which senior Park management is committed can be realized and sustained. The report prepared by Ecos is truly a gift to the Park.”
- Chuck Koob, Simpson Thacher & Bartlett LLP

“It’s one thing to talk about the importance of cost-effective energy efficiency and quite another to make it happen reliably on a large enough scale to matter. Ecos has proven repeatedly that it can deliver inexpensive energy savings for the most demanding constituents, and in doing so it has created an invaluable environmental and economic dividend for all the rest of us.”
- Ralph Cavanagh, Senior Attorney and Energy Program Director for NRDC

“Companies like Ecos are crucial to helping solve the environmental crisis at hand. For many years now, Ecos has developed and executed innovative projects that get to the heart of the problem. They’ve really captured the essence and vision a company needs in order to make a measurable impact on the environmental emergency facing this planet…”
- L. Hunter Lovins, President, Natural Capitalism Solutions

- John W. Hargrove, Senior Project Manager for Sierra Pacific and Nevada PowerENERGY STAR® Programs

- Tom Hines, program manager of the APS ENERGY STAR Residential Lighting Program

- Paul Zambernardi, Executive Director of the Yellowstone Park Foundation

“…In a world too often filled with greenwashing and eco-hype, Ecos provides its clients with a commendable level of integrity and conviction. Employees have a deep understanding of how markets work.
