I delivered a masterclass on ‘The Expanding World of New Tech and its Sustainability Implications Focus: How can businesses leverage new technology to meet climate goals and consumer demands?’ to the students of the Institute of Sustainability Studies in November 2025. The session focused on the intersection of emerging technologies and corporate sustainability goals, particularly addressing the challenges faced by the energy-intensive industrial sector. The presentation identified five key innovations: AI-Powered Energy Management, Vertical Farming, Blockchain Product Passports, Carbon Capture/Utilization/Storage (CCUS), and Green Hydrogen -- as central to transforming climate action today. For each technology, I evaluated its potential for both carbon reduction and economic viability, analyzing specific challenges like energy intensity or high capital investment costs. Crucial recurring themes included the necessity of data-driven reporting to verify sustainability claims and how digital tools enable the principles of the circular economy. Furthermore, I provided practical recommendations tailored for UK/Ireland small businesses to align their technology investments with policy frameworks, consumer trust, and long-term financial planning.
