The climate crisis will destroy our economies – we learned this 20 years ago. When will we act? | Fiona Harvey

I reviewed Fiona Harvey’s commentary in The Guardian reflecting on the 20‑year reach of Nicholas Stern’s 2006 review and its economic case for early, large‑scale climate action. The piece argues that mainstream economics once undervalued the planet, and that Stern’s work — which framed climate policy as prudent risk management and long‑term investment rather than short‑term cost — should have changed capitalism’s trajectory. The Guardian commentary is the prompt for this synthesis (The Guardian, opinion piece by Fiona Harvey, Oct. 28, 2026).

What Stern argued, and why it matters now Two decades after the Stern review, its central proposition remains influential in policy circles: unchecked climate change imposes systemic, long‑run economic damages that dwarf the costs of mitigation today, so investing now yields net economic benefits. European policy documents and analyses today treat climate risk as a core economic risk to jobs, infrastructure and fiscal stability, endorsing the Stern framing that adaptation and mitigation are investments in resilience and competitiveness rather than mere expenditures. The European Commission’s recent climate resilience package frames adaptation as necessary to “protect jobs and livelihoods, and create new opportunities for European innovation and investment,” and presents tools (a European Climate Viewer, a Navigator of Climate Resilience Tools, and other instruments) intended to help authorities assess and manage those economic risks.

Policy responses since Stern: partial, uneven, accelerating European Commission publications and communications show an increasingly institutionalised response: climate policy is being mainstreamed into budgeting, regulatory planning and economic forecasts. The Commission now links decarbonisation and resilience explicitly to competitiveness and fiscal policy, sets binding targets under the European Green Deal, and has proposed mechanisms to direct EU budget spending toward climate objectives (including a 35% climate‑related spending target in planning for the 2028–2034 framework). These actions demonstrate that public authorities have accepted the Stern insight that economic stability and climate policy are intertwined — and that protecting economies requires anticipating climate impacts rather than reacting after disasters.

Costs, limits and remaining uncertainties Commission analyses also reflect Stern’s caution about uncertainty. Integrated assessment models and sovereign‑debt frameworks are now being adapted to include climate risk scenarios; but official work also stresses modelling limits and the need for ensembles of approaches to reduce misspecification. The Commission’s examinations acknowledge that adaptation investments reduce vulnerability over time yet can’t eliminate physical risk, and that economic forecasts must factor in energy shocks, inflationary effects and transition costs. In short, policy makers have adopted Stern’s logic while wrestling with the practical complexity of translating that logic into fiscal and industrial policy.

Implications for action today The core lesson — that early, sustained investment in mitigation and adaptation is economically rational — has been absorbed into EU strategy, but the Commission’s materials also underline the unevenness of implementation and the persistent political challenge of mobilising private capital at scale. Harvey’s provocation — that capitalism needs a reminder — resonates: institutions have largely accepted the diagnosis, yet the pace and scale of measures still fall short of pathways that would substantially reduce long‑term economic damage. The European Commission’s recent resilience framework and ongoing Green Deal measures show policy is shifting, but they also expose practical trade‑offs, funding needs and model uncertainty that must be resolved to turn Stern’s argument fully into outcomes.
