As demand for always-on connectivity and AI accelerates, digital infrastructure is driving rapid growth in energy use and emissions - just as consumers and governments expect seamless performance and expansion. In this fireside chat, Dana Haidan, Chief Sustainability Officer of Virgin Media O2, explores whether digital growth can truly align with science-based climate targets, and why efficiency across networks, data centres, devices, and operations is the critical unlock. The conversation will examine how smarter design, AI-enabled optimization, and policy alignment can help decouple digital expansion from environmental impact, and what this means for sustainability leadership in a hyper-connected, resource-constrained world.
