38 UK zones are exceeding EU air pollution limit values. An entire zone is considered to be in exceedance if any point within the zone boundary is in exceedance. While only 17.6% of total modelled road length exceeds EU limit values, the total land area covered by the 38 zones is equivalent to 72.6% of the total UK land area, but the points within the zones which are in exceedance cover a much smaller land area.
