Health costs of clean air zones: what's the price?

Gabriel Kroon (SD) proposed that the City of Stockholm conduct a health economic evaluation of environmental zones class 2 and 3 to determine if the cost per quality-adjusted life year (QALY) gained is reasonable, arguing that current studies suggest high costs compared to other public interventions and significant economic impact on individuals and businesses. The City Executive Office, Environment and Health Committee, and Traffic Committee rejected the proposal, stating that the city already monitors the zones' effects on air quality, that the positive health effects outweigh the costs, and that such an evaluation would be unreliable due to data scarcity and long-term effects.
