Inogen global EHS and sustainability consulting on every continent

Inogen Environmental Alliance

Global Thinking. Local Delivery.

The Inogen Environmental Alliance is a global network composed of partnering consultancies that provide multinational organizations with consistent, high-quality, and cost-effective environmental, health and safety solutions. Together by choice, each Inogen Associate is a successful, independently operating company with global understanding of current EHS issues combined with local resources and regulatory knowledge in the regions they serve. 

Through Inogen’s innovative business model, a single point of contact directs client work seamlessly anywhere in the world from global program implementation to local project completion. Additionally, defined practice standards set uniform methodologies for work, and a contract with one Inogen Associate allows access to the entire network – there is no need to enter into separate contracts with each Associate. 

A proud founding member of Inogen, Antea Group helped establish the network in 2001 to better serve global clients. With more than 200 offices located on every continent and more than 6,430 staff worldwide, our partnership with Inogen provides us with an enhanced global capacity and a geographic reach unparalleled in the industry.
