The Inogen Alliance operational structure is distinct when compared to peer organizations. We are unified as an Alliance of independent companies rather than joined as a single entity. This structure has provided our teams with the autonomy and local dexterity to consistently deliver results to our clients.

The scope of our current ESG Policy focuses on impacts driven by our collaborative engagements as an Alliance, primarily through the Alliance operations and meetings. Those impacts are what will be reflected within this ESG report.


1 Inogen Alliance operations (primarily meetings and travel)
2 The activities of our independent Associates representing nearly 80 firms with more than 200 global offices
3 Our influence on thousands of clients to advance their company EHS&S practices

Our teams made progress in 2022 in measuring company-specific impacts, setting targets, and taking action within our local communities through social initiatives. Inogen Alliance aligned our carbon inventory to the GHG Protocol and improved the precision of our calculation. Our 2022 screening exercise estimates a Scope 3 footprint of 30.54 tons of CO2 equivalent. Moving forward, our priority as an Alliance is to continue to improve our calculation methodology and take deliberate actions to reduce emissions associated with Inogen Alliance activities.


I am pleased to share the second annual Inogen Alliance Environmental, Social, and Governance (ESG) Report. Our 76 companies and 6,000 consultants work with many of the leading multinational organizations around the world. The Alliance has supported 90% of the top 10 technology companies globally, and at least 30% of Fortune 100 companies, helping them to meet their Environmental, Health and Safety, and Sustainability (EHS&S) goals. Our ability to influence the success of these organizations in meeting their ESG goals will continue to drive our efforts in the future.

Now more than ever, as we are faced with the complex challenges of climate change and the imperative of reaching net zero, we recognize that the collective knowledge across our global teams brings innovation, energy, and commitment to the environment, health and safety and sustainability challenges we face.

Within the 2022 calendar year, we launched several deliberate initiatives to leverage the unique insights and expertise from across our global teams. Inogen Alliance Working Groups have been a core priority and area of expansion. Our Working Groups were organized as a means for global Associate teams to connect on a routine basis for dialogue and alignment on key strategic solutions to support client needs and challenges.

As the European Union (EU), United States of America (USA), and nations around the world passed legislation to curb climate change and facilitate the energy transition,

the Inogen Alliance Energy Transition Working Group pulled together our expert teams from across the globe to strategize on how to best support energy sector clients and make a meaningful impact within our regions. Similarly, as the United Nations Biodiversity Conference (COP15) convened in Montreal, our Sustainability Working Group hosted roundtable discussions with biodiversity and ecology experts from our Associate teams in France, Sweden, and Bulgaria.

In 2022, we were pleased to expand our thought-leadership to a short documentary focusing on climate change and environmental impacts, released by Global Thought Leaders. This short film was distributed through global channels including CBS News, The Independent, and Gulf News, further communicating our story and ambitions to mitigate climate change through our global consulting expertise.

The Environment Analyst recognized Inogen Alliance among the top 30 global environmental consultancies in 2022. It is an honor to be recognized for our global reach, which contributes to the exceptional quality of services that we deliver. I’m grateful for the exemplary work of our global teams and the insights of our experts who made this achievement possible. I look forward to future Inogen Alliance successes and collaborative efforts to make local commitments a global reality for our clients and the communities in which they operate.

President of Inogen Alliance
