OSIEC

OSIEC is a leading environmental and social advisory firm, firmly rooted in Africa and focused on shaping sustainable futures.

Established in Senegal in January 2020, the firm has rapidly built a strong reputation as a trusted partner for the development of strategic energy and infrastructure projects across the continent.

OSIEC provides support across the full project lifecycle, delivering integrated solutions in environmental and social risk management, international standards compliance and operational implementation. Its capabilities include impact assessments, environmental and social management systems, resettlement planning, biodiversity management, stakeholder engagement, grievance mechanisms and field-based performance monitoring.

The firm’s distinctive strength lies in its ability to convert complex requirements into pragmatic, context-specific solutions tailored to African operating environments. By aligning international investor expectations with local realities, OSIEC helps ensure the successful delivery of projects that are sustainable, value-creating and investment-ready.

With a strong regional footprint and proven mobilisation capacity, OSIEC supports major projects across West and Central Africa. The firm has developed particular expertise in the energy sector, especially renewable energy and electrical infrastructure.

Since July 2024, OSIEC has entered a new phase of growth through its strategic integration with Synergy Global Consulting. This partnership combines international expertise with in-depth local insight, creating a platform capable of delivering sustainable, high-impact projects that meet both local realities and international expectations.

Together, OSIEC and Synergy provide integrated environmental, social and engineering solutions that bring together ESG performance, technical rigour and operational efficiency.

OSIEC is more than a consulting firm; it is a committed strategic partner to those helping shape Africa’s future.
