Living Greens Screens have proven particularly effective when placed on highly polluted streets with buildings on both sides (street canyons), where the air pollution
is higher at street level than the area above the surrounding buildings.
This has made them ideal for use in street planting schemes, forming a roadside barrier for highly localised protection from polluted air.
This was demonstrated by one study by King’s College London that found levels of NO2 reduced by 23 per cent when green screens were placed between a busy road and a school playground.
