Direct peers

• ERM (Environmental Resources Management): ERM is the largest pure-play global EHS and sustainability consulting firm, with 8,000+ professionals across 40+ countries. It is the closest direct competitor to Inogen's multinational EHS&S value proposition and competes head-to-head on ESG advisory, climate, and environmental due diligence.
• Ramboll: Ramboll is a global engineering, design, and consulting firm with a strong Environment & Health practice serving multinational clients on EHS, sustainability, and climate projects. Its Nordic roots and global footprint make it a strong functional peer to Inogen's network.
• SLR Consulting: SLR is a global environmental and sustainability consultancy with 2,500+ staff across multiple continents, offering EHS advisory, environmental due diligence, and ESG services. It competes with Inogen for mid-to-large multinational consulting engagements.
• Antea Group: Antea Group is both a flagship Inogen Alliance member (and previously Angelique Dickson's employer) and a competing global EHS consultancy in its own right, operating in the US, UK, Belgium, France, Netherlands, and Brazil. It illustrates the channel conflict inherent in Inogen's alliance model.

Broad incumbents

• WSP Global: WSP is a global engineering consultancy with a significant Environment and Earth Sciences practice, including EHS consulting, climate resilience, and sustainability advisory. It competes with Inogen on large multinational infrastructure and environmental engineering mandates.
• AECOM: AECOM is a global infrastructure consulting firm with a large Environment practice covering EHS compliance, environmental engineering, and ESG advisory. Its scale and integrated delivery model position it as a broader incumbent competing for the same multinational RFPs as Inogen.
• Arcadis: Arcadis is a global design and consultancy firm with significant EHS, sustainability, and climate advisory capabilities serving multinational industrial and infrastructure clients. It directly overlaps with Inogen's environmental engineering, due diligence, and sustainability service lines.
• Stantec: Stantec is a global engineering, architecture, and environmental consulting firm with established EHS, water, and sustainability practices. It competes with Inogen in environmental engineering, water/wastewater, and ESG advisory for multinational clients.

Emerging players

• Watershed: Watershed is a leading enterprise climate platform for carbon accounting and ESG disclosure. While a software company rather than a consulting firm, it increasingly competes for the same enterprise ESG budget that Inogen serves, particularly around CSRD and climate disclosure mandates.
• Workiva: Workiva is a cloud-based platform for ESG, sustainability, and regulatory reporting used by large multinationals. It competes with Inogen's ESG Assessment Tool and global sustainability reporting services for enterprise disclosure budgets.
