Steve and team are responsible for a whole range of climate activities including providing learning for the organisation, outreach programmes and working with suppliers to help them decarbonise. Steve now works closely with Natwest's Head of Responsible AI and Strategy to both try and measure the environmental impact of the Banks use of AI and what levers the organisation has to mitigate any impact.

Responsible AI Summit Main Conference Day 2 - Tuesday 22 September

4:00 PM Afternoon Plenary Panel Discussion – The Real Cost of AI: Sustainability, Energy & Accountability

AI’s rapid expansion carries a growing environmental footprint, from data centre infrastructure and hardware supply chains to model training, inference, and everyday user behaviour. Yet much of AI’s carbon impact remains opaque, distributed, and poorly measured. As adoption accelerates, organisations must ask a harder question: what is the true sustainability cost of AI, and who owns it?

This panel moves beyond awareness to break down AI’s carbon use spectrum: infrastructure, operations, and behavioural demand. Speakers examine where emissions concentrate, how to distinguish high-value use from low-value usage, and what practical interventions can meaningfully reduce impact without stalling innovation.

• Measuring emissions across the full AI lifecycle.

• Identifying high-impact vs low-value AI usage.

• Embedding sustainability into governance and daily practice.
