Columnist: Two decades of ignored climate-economics warnings
Fiona Harvey argues that economists demonstrated long ago that climate action serves economic interests, yet policymakers have failed to act on this knowledge.

What This Means
This is commentary, not reporting. Harvey argues that the economic case for climate action has been established for two decades yet policy and investment remain misaligned with the scale of risk. The mechanism is straightforward: unpriced climate damages—to supply chains, asset values, insurance costs, and labor productivity—create a gap between market prices and actual economic exposure, leaving portfolios and economies vulnerable to sudden repricing when physical or policy shocks force recognition of stranded assets and disrupted production.

How This Could Play Out
First assessed Oct 28
Resolved
UNLIKELYCarbon-intensive equities and fossil fuel assets reprice downward as regulatory frameworks embed climate risk into cost of capital, while renewable energy and climate-resilient infrastructure attract sustained capital flows.
Status quo
LIKELYAsset prices remain disconnected from unpriced climate damages; volatility spikes episodically around climate events and policy announcements, then subsides as markets revert to short-term discounting.
Worsens
POSSIBLEA cascade of physical shocks or sudden policy shifts forces rapid repricing of stranded assets, triggering credit stress in climate-exposed sectors and sharp drawdowns in portfolios concentrated in carbon-intensive holdings.
