30 snips
Nov 9, 2025 Prof. Sir Dieter Helm, a leading economic policy expert from the University of Oxford, critiques the current climate strategy as a 'self-delusion.' He argues that decades of COP efforts have failed, revealing how green policies may actually harm the West while benefiting China. Helm highlights the heavy reliance on fossil fuels and points out the unrealistic nature of targets like Net Zero 2050. He calls for a shift in focus towards effective, cost-conscious decarbonization and warns against misleading voters about the true costs of climate policies.

- Helm links Britain's deindustrialisation partly to expensive energy policy choices.
We Locked In High Energy Costs
