Particles Norway's "most costly" air pollutants
Calculations of the "socio-economic costs" of 11 atmospheric pollutants in Norway show particulates (PM10) to be the most harmful, the pollution control authority (SFT) reports. Cost estimates of NKr1600-5500 (€198-680) per kilo mean that if Oslo alone were to cut traffic particle emissions 10%, "society would save NKr50-120m every year in reduced damage to health", it said. Marginal costs associated with long-range pollutants (NOx and SO2) were also highest in the largest cities, while economic damage caused by the six greenhouse gases was "completely unrelated to where the emissions take place".
