Better prompts save time and carbon | The real cost of AI with Seb Royce

This webinar explored how marketers can use AI more sustainably through better prompt engineering, right-sizing AI models, and understanding their AI supply chain. We cover the environmental impact of large language models, data centre energy use, and how tracking prompt efficiency acts as a sustainability intervention. Topics include conscious creativity, digital carbon footprint, work footprint, and practical steps for reducing AI energy consumption at work. Every time AI comes up in a marketing conversation, someone asks: "But what about the planet?" This webinar is the answer to that question. Seb Royce, Creative and Communications Partner at Eden Lab, joined us as someone who's been sitting with this tension for years. He loves AI. He uses it every day. But he's also a marketer who audited his own work footprint, took a course at the Cambridge Institute for Sustainable Leadership, and came out the other side with a framework he actually uses. Not a list of things to feel guilty about. A practical way of thinking about the choices you're already making.
