As mentioned in our first blog entry only one in 10 buildings in Washington D.C. area have green roofs. But what if they all did? Well, scientists in Michigan recently calculated that replacing traditional roofing materials in an urban area the size of Detroit with green would be equivalent to eliminating a year’s worth of carbon dioxide – a greenhouse gas – emitted by 10,000 mid-sized SUVs and trucks!
About 600,000 people live in Washington, D.C., and about 8 million live in the Washington-Baltimore metropolitan area. So, small things like converting to green roofs can have a big impact on our lives.
