Lowering the levels of carbon dioxide from car emissions by planting more hedges

In urban areas and crowded city centers with high levels of car emissions, the hedges are a much better solution than trees when it comes to coping with carbon dioxide and other pollutants, because the hedges are planted level with car exhausts.

Scientists claim that this helps in lowering the effects of harmful carbon emissions. Profesor P. Kumar from the Surrey University states that the hedges are a lot more efficient in stopping harmful air particles coming from the car exhausts for one reason only – they are planted much lower and therefore absorb exhaust emissions much faster. This way people are less exposed to polluted air.

The plan

He also suggests that cities should plant a lot more hedges between the sidewalks and the roads, if there is enough space for that. His team of scientists from the United States and the European Union are still searching for the plants that would be the most efficient in absorbing carbon dioxide, the main cause of global warming. They are also researching what wold be the best height for these hedges to make them as efficient as possible. They stress that  these statements are not directed towards reducing the number of trees in urban areas, but towards the efficient combining of both trees and hedges. The trees absorb great amounts of CO2 and they are extremley useful, but the hedges would be significantly helpful in making this green system more efficient. Serving „at the front line“ between car emissions and the people living in urban areas, the hedges could help in preventing diseases and health hazards that harmful car emissions cause.
