The Institutional Investors Group for Climate Change has published a report assessing the UK’s success in capturing the economic opportunities of the energy transition, arguing that the priority now is to convert climate ambition into investable opportunities at scale. It sets out five areas for government action: move from strategy to delivery through a whole-of-government approach, strengthen industrial strategy by aligning public finance institutions and sector priorities, scale adaptation and resilience investment, operationalise nature markets, and deliver a coherent financial regulatory framework including UK Sustainability Reporting Standards and mandatory transition plans for high-impact sectors. The report supports that case with figures showing the green economy grew 10% in 2024 while the rest of the economy was flat, and says that by June 2026 the UK’s net zero economy was generating about GBP 105 billion in gross value added and supporting 1.1 million full-time equivalent jobs. It identifies energy costs as a central constraint on competitiveness and investment, and calls for clearer policy signals, stable frameworks, stronger delivery mechanisms, more visible investment pipelines, better support for adaptation finance, and more comparable sustainability and transition disclosures. It concludes that institutional capital remains available, but only where policy is clear, durable and credible.
