Trees: Roads

Question: To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment she has made of the importance of street trees in reducing urban pollution; and what plans she has to increase the number of street trees in the forthcoming air quality plan being prepared by her Department.
