Pierre Klemas

Chief Sustainability Officer , Stirling Square

Leading the integration of sustainability and responsible investment practices across the investment lifecycle and portfolio value creation at Stirling Square.

With 20+ years’ experience across multinational and multidisciplinary engineering projects, energy EPC, infrastructure, sustainability and private equity investing, I focus on embedding ESG as a driver of resilience, operational excellence and long-term value creation.

I hold a degree in Physics Applied to Architecture from Université Pierre et Marie Curie and an MBA from ESCP Business School, combining scientific, technical, strategic and investment perspectives.

My work focuses on supporting businesses in identifying material sustainability risks and opportunities, developing practical and measurable roadmaps, and translating sustainability priorities into concrete actions across their value chains.

I aim to help companies protect value, strengthen performance and unlock sustainable growth through pragmatic ESG integration, decarbonisation, responsible governance and stakeholder engagement.
