Long before green was fashionable, Delaware North set about the task of establishing an environmental management system to help protect the parks in its care. That was the beginning of GreenPath®, the first environmental management system of a U.S. hospitality company to be registered to the standards put forth by the International Organization for Standardization (ISO 14001).

Now in place companywide, GreenPath has made a remarkable difference. It has helped us divert thousands of tons from the solid waste stream, save millions of gallons of water, reduce energy consumption and devise new and better ways of doing things.

From our facilities team becoming Leadership in Energy and Environmental Design (LEED) certified so that we can continue to bring an environmentally responsible approach to all of our building projects, to hosting green meetings at our destinations, we are leading the way in environmental management for a hospitality company.

And if accolades from our guests and the 40-plus awards GreenPath® has won are any indication, it is by far one of our most successful endeavors of late.


The company’s environmental management program – GreenPath® has received numerous honors including from the Department of Interior.
