Sessions
Keynote: Sustainability ROI
Taylor Francis kicks off the event with a keynote exploring the business value of sustainability. He highlights how sustainability data can be used to improve operational efficiency, reduce risk, and uncover new revenue opportunities.
State of decarbonisation
Watershed’s Head of Decarbonisation, Matt Konieczny unpacks the latest trends shaping the decarbonisation landscape. As electricity demand—fueled by data centers and AI—outpaces infrastructure growth, and carbon removal markets face a supply crunch, companies are under pressure to rethink their strategies. With nearly half of Fortune 500 companies pursuing net-zero targets, this talk explores how businesses can navigate market volatility through proactive purchasing, strategic credit selection, and collective negotiation to meet their decarbonisation goals.
A conversation with Paul Polman
Watershed’s Head of Europe, Ellen Moeller McCormack, sits down with Paul Polman—former CEO of Unilever and co-author of Net Positive—to explore how business success and sustainability are not just aligned, but fundamentally interconnected. Drawing from his experience leading Unilever’s Sustainable Living Plan and his work since, Paul shares timely insights on long-term value creation, navigating today’s shifting ESG landscape, and the bold leadership required to build companies that thrive by solving the world’s biggest challenges.
Sustainability in practice: insights from three leaders
To close out the event, Watershed’s Naina Khandelwal moderates a conversation with three sustainability leaders driving impact across different sectors: Salah Said, Head of Sustainability at Klarna; Chloë Sanders, Head of Sustainability at CVC Capital Partners; and Matt Gower, Head of ESG at Royal Mail. Together, they share practical stories of how sustainability is creating business value—through revenue growth, risk mitigation, and operational improvement. The discussion covers how to secure internal investment, measure impact, and navigate an evolving regulatory landscape with clarity and confidence.
