The world’s largest pure play sustainability consultancy, ERM, has acquired Stratos Inc., one of Canada’s leading sustainability and ESG advisory firms.  

As a management consultancy with more than 20 years’ experience working across industry, government, indigenous organizations and civil society, Stratos adds over 30 Canada-based sustainability and ESG practitioners to ERM’s +5,500-strong firm. The company brings deep expertise in ESG performance and risk management, stakeholder engagement, science and innovation, conservation and regulatory excellence, as well as a commitment to advancing Indigenous reconciliation through meaningful partnerships and collaboration.  

This acquisition further strengthens ERM’s leading capability in sustainability and climate change advisory services and builds on recent acquisitions including Sustainalize in 2021, M. J. Bradley & Associates and Critical Resource (both in 2020), SustainAbility in 2019 and BrownFlynn in 2018.

Keryn James, CEO, ERM said: “As organizations look to transition to a low-carbon economy, they look for partners that can help not only strategize solutions, but also implement them. With the acquisition of Stratos, we are further strengthening our capabilities and capacity to support clients in Canada and beyond as they navigate these increasingly complex issues. We are thrilled to welcome Stratos to the ERM Group.”

Stephanie Meyer, President of Stratos, shared “We are very excited to be joining the ERM team. Global financial markets and governments are pulling economies toward net zero carbon transitions and more sustainable and inclusive practices. In response, businesses and public sector organizations need new approaches and strategies underpinned by strong technical analysis and engagement. Together with ERM and our Indigenous partners, we can offer this full suite of services to support these transitions.”
