Green Roofs Help Improve City Air Quality
Popular in Europe for some time now, green roofs are becoming more and more common in the United States; good news for those concerned with city air quality.  A green roof is a roof that has been covered with vegetation rather than left bare, and there are two main types that are used. “Intensive” roofs, which are thick, green, and lush with deep soil, usually are intended to be used by people in much the same way as an ordinary garden, and will often have benches and walkways for people who live or work in the building to enjoy.  “Extensive” roofs, on the other hand, tend to have shallower soil and are used for the benefits that the plants provide while being generally off-limits to human visitors.  Scientists are studying the benefits of both kinds of green roofs, and have found that they not only can they contribute to reducing air pollution, but they can help with things like water management and can even last longer than traditional roofing.   One exciting benefit of having green roofs is in the reduction of carbon from the air, which helps to improve air quality and make local air better to breathe.  One 2009 study found that in the right conditions, using green roofs throughout an urban area with a population of around a million people could remove as much carbon from the air as one would get from taking 10,000 SUVs off of the road.

The spread of green roofs should be exciting news for those who live in areas with higher density populations.  Smog and other increases in air pollutants, caused by traffic or industry, can have quite a negative impact on health, from allergy-like symptoms, such as itchy eyes and congestion, to more serious ailments, such as heart or lung disease. It is hoped that widespread use of green roofs could significantly improve air quality, and that could mean a significant improvement in health as well.  In the meantime, for those wanting to breathe better air at home, adding an air purifier with a charcoal based activated carbon filter, like our MinusA2 and BioGS models, can help to filter out the toxins from smog and other airborne chemical pollutants to keep indoor air quality high.
