Climate Disinformation Model Shows Carbon Taxes Can Collapse Once Misinformation Tips Majority

New research from University College Dublin and the ILaVita Foundation, published in the KeAi journal Risk Sciences, builds disinformation directly into a climate-economy model. It compares carbon tax outcomes under majority voting versus a politically constrained planner. When informed voters hold the majority, voting can produce stronger carbon taxes and lower peak warming. That advantage disappears abruptly once disinformation flips the majority, pushing policy off a cliff. Late or persistent disinformation is the most damaging because it erodes support after strong policy has already started. The model also finds that a sufficiently strong counter-disinformation campaign can largely offset an early disinformation shock. The authors frame protecting the information environment as part of climate policy, not just democratic quality. DOI: 10.1016/j.risk.2026.100063.

The interesting part is the cliff edge. The model says majority voting can beat a constrained planner until disinformation flips enough voters. That matches the real world problem: carbon taxes are politically fragile. Worth reading for anyone tracking carbon pricing feasibility.

Good to see a model that doesn't assume voters know the actual climate damage. The counter-disinformation result is the key one. If a decent response can undo an early disinformation shock, then information policy becomes part of the carbon price story.

The comparison between voting and a constrained planner is useful, but the model depends on how the disinformation shock is timed and sized. The authors say late and persistent shocks cause hothouse trajectories. I'd like to see how sensitive that is to the assumed learning rate.

Simple summary: informed majority can push carbon taxes harder than a cautious planner, but disinformation can erase that advantage fast. Late or long-lasting disinformation is worst. Counter-disinformation helps if it is strong enough.

The paper adds disinformation to the usual cost-benefit math. Main takeaway: carbon pricing doesn't just need economic design, it needs voters who understand why the price exists. If the information environment collapses, the policy goes with it.
