The Transformative Power of Materials and Surface Engineering: Revolutionizing Net Zero Transitions and Unleashing Economic Resilience

The global transition to net-zero emissions has sparked intense debate about its economic ramifications, particularly following revelations of potential GDP contraction linked to rapid decarbonisation strategies. A 2025 UK government analysis projecting a 10% GDP reduction by 2030 under aggressive net-zero policies highlights the risks of stranding productive assets and inflating costs through forced technological replacements. However, this discourse often
