Celebrating 25 Years of Inogen Alliance: A Milestone in Global EHS & Sustainability Leadership

This year marks a significant milestone for Inogen Alliance: 25 years as a global Alliance dedicated to advancing environmental, health, safety, and sustainability (EHS&S) outcomes for multinational organizations around the world. From our founding in 2001 to our evolution into a trusted partner for multinational clients, our journey reflects both deep heritage and forward-looking ambition in an era defined by accelerating environmental and societal challenges.

The Power of Alliances in Today’s World

Over the past months, many of us have felt the strain of uncertainty and division in the world around us. In times like these, the Inogen Alliance gives me genuine hope. Our Alliance is a living example of what is possible when people from different cultures, backgrounds, and perspectives choose to work together with mutual respect. It reminds me every day that collaboration, empathy, and shared purpose are not abstract ideals, but values we actively practice through our work together. In these uncharted times, I encourage all of us to look at the Alliance as a model for what constructive, values‑driven partnership looks like.

Alliances like ours represent a powerful model for collective action. Rather than a large global firm, our network of independent consultancies brings together diverse perspectives, localized knowledge, and shared commitment to solving complex challenges. This model fosters innovation, reinforces resilience, and amplifies impact. These attributes are increasingly vital as organizations strive to balance growth with sustainable performance.

As businesses and societies look toward a future defined by environmental uncertainty and opportunity, the Alliance’s collaborative approach, grounded in shared purpose and global-local solutions, offers a blueprint for how partnerships can drive meaningful change at scale.

A History Rooted in Collaboration and Purpose

Inogen Alliance began as a bold idea: a network of independent EHS&S consultancies that would come together to offer seamless, high-quality services across borders through one point-of-contact. What set us apart from traditional global firms was our innovative model: local consultancies with specialized regional knowledge and regulatory expertise collaborating under a unified framework to serve global clients with consistency and local understanding.

In the first decade of the Inogen Alliance the challenge was convincing the global EHS market that our new innovative way to providing global EHS services would work. Today that is no longer a concern. Today, the market is demanding high quality, knowledgeable EHS resources in-country.

In the early years, this model proved especially powerful for organizations facing complex multinational EHS challenges that required both global coordination and local nuance. By connecting expert consultants from different countries, the Alliance enables clients to navigate varied regulatory landscapes, cultural contexts, and operational realities all through one point of contact and one global contract.

Over the last quarter-century, this unique structure has allowed us to build long-lasting, trusted relationships with clients across industries, from energy and chemicals to technology, retail, food and beverage, and beyond, delivering solutions that balance compliance, risk management, sustainability performance, environmental liabilities and strategic growth.

Growth, Evolution, and Strategic Impact

What started with a handful of Associate consultancies has grown into a vibrant global network with 70+ Associates, more than 6,000 consultants, and projects delivered in over 150 countries. This breadth of reach, paired with the depth of local expertise, is a defining strength of the Alliance, enabling clients to access tailored solutions wherever they operate.

Over the years, Inogen Alliance has expanded capabilities beyond traditional EHS compliance into strategic sustainability services including climate change and decarbonization consulting, water stewardship and conservation, biodiversity protection, and ESG advisory. These expanded offerings reflect the evolving needs of global organizations and underscore our commitment to helping clients not only meet requirements, but also lead in business resilience and sustainability performance.

Recognitions like being ranked #37 in Environment Analyst’s Global Environmental & Sustainability Consulting Market Assessment highlight the stature of the Alliance in the broader consulting landscape and affirm the value of a collaborative model in driving meaningful impact for clients and communities.
