Two recent articles have come to our attention via the European Commission Science for Environment Policy. They look at the benefits of urban greening – the first relating to green walls which can lower energy consumption, support biodiversity and reduce flooding. This particular report explores the benefits green walls can also have on noise pollution.
The second refers to urban trees and their ability to trap pollution. It considers new research that shows that careful planting and ongoing pruning is required to ensure the trees can trap particulate matter pollution most effectively.
This follows a number of articles that also look at how trees and urban greening can help reduce particulate matter from road traffic in cities and indoors, with one paying particular attention to how effective birch can be in this area.
