We are thrilled to invite you to an inspiring event dedicated to transforming your digital future into a sustainable one.
In today’s complex landscape, Danish companies face increasing challenges due to geopolitical tensions and vulnerabilities across digital supply chains—from microchips and hardware to devices. These risks are compounded by dependencies on the electricity grid, data centre stability, volatile energy prices, rising IT licensing costs, and growing demands for transparency around digital CO₂ emissions. As these challenges grow, understanding their impact across sustainability, resilience, finance, and IT is more important than ever for future-proofing your business.
Join us for an afternoon filled with inspiring talks and engaging conversations, followed by pizza and the opportunity to connect with like-minded professionals at Deloitte x IBM’s Green IT after-work session.
