This paper studies the impact of speed limits on local air pollution using a series of datespecific speed limit reductions in Oslo over the 2004-2011 period. We find that lowering the speed limit from 80 to 60 km/h reduces travel speed by 5.8 km/h. However, we find no evidence of reduced air...

We find that lowering the speed limit from 80 to 60 km/h reduces travel speed by 5.8 km/h, but we find no effect on local air pollution....
