In some cases, they use a series of modified recycled plastic trays, held in place with ballast alone, to produce an astonishing 45 percent reduction in roof runoff during rainfall events.

Using a variety of active and passive water collection methods and techniques, the work is considered to be at the forefront of blue-roof testing. In 2015, New York City renewed its commitment to sustainability with the One NYC rcs data initiative—an extensive measure to create sustainable rooftops all over the city and an example of how blue-roof technology will be a central part of sustainability in cities in the future.

Around the globe, parallel efforts are similarly taking shape to try to offset the host of issues being created by impervious surfaces. In 2012, a British-led project by the Imperial College of London called the Blue Green Dream (BGD)—an initiative part of the wider European Union Climate Knowledge and Innovation Community (KIC)—began an ambitious project to introduce blue and green roofs across London and the European continent.
