Green Roof Benefits Quantified

A new study has shown that the environmental benefits of green roofs are even greater than previously thought.

"[R]esearchers have attempted to quantify the benefits of covering urban rooftops with plants. The scientists found that replacing traditional roofing materials with ‘green' in an urban area the size of Detroit with a population of about one-million, would be equivalent to eliminating a year's worth of carbon dioxide emitted by 10,000 mid-sized SUVs and trucks. Their study is the first to examine the ability of green roofs to sequester carbon that may impact climate change and the findings are scheduled to appear in the journal Environmental Science & Technology."
