Monday Keynote: Keynote Address - Becoming Critical – Cooling as Critical National Infrastructure This compelling keynote session will explore how the cooling industry has evolved into a cornerstone of modern infrastructure — not just for maintaining comfortable spaces in which to live, work and play, but more broadly across a wide range of vital sectors. From commercial air-conditioning and food cold chains, to health products distribution, industrial processes, transport and data centres, you’ll learn how cooling is now a “mission-critical” service essential to public health, food security, global commerce, and economic well-being. The session will take a global perspective, highlighting the challenges ahead as the planet continues to warm and climates experience significant change, as well as the importance of international collaboration and coordination in delivering viable, deliverable solutions. You’ll gain valuable insights into how governments view critical infrastructure, the importance of recognising cooling as such, and progress towards achieving that status in the UK and beyond. Vitally, you will understand the implications for society of ignoring the importance of cooling as mission critical, not only in terms of the direct human costs, but also the trade, commerce and economic development losses and, ultimately, degraded national security and stability. What you’ll learn:

Workshop: Workshop - EU ENOUGH Workshop The ENOUGH project aims to reduce greenhouse gas emissions in the food sector, which contributes 20–40% of global emissions.It aligns with the EU Farm to Fork strategy, providing tools and methods to help food businesses achieve climate neutrality. The project objectives are to define pathways to climate-neutral food businesses, enhance sustainability across the food supply chain and inform policy makers, businesses, and stakeholders about innovative solutions for reducing emissions. The project has demonstrated practical solutions across various stages of the food chain, including processing, transport, retail, and domestic consumption, focusing on products such as meat, fish, fruits/vegetables, and dairy. This meeting will provide an opportunity for partners to reflect on the project’s outcomes and explore future opportunities for applying the demonstrated solutions at scale.
