Each year, billions of gallons of rain runs off water-impervious surfaces such as concrete, metal, and asphalt. This water overwhelms sewers, resulting in rainwater mixing with waste and leading to health threats, beach closures, habitat degradation and swimming and fishing advisories. To help combat this, American Rivers created green rooftops that can trap and filter storm water rather than allowing it to run into sewers. The roofs go beyond health and provide cost benefits to both people and businesses as they greatly reduce heating, cooling and repair expenses.
To get the word out about green roofs, we created an online tool that helps show companies how they can “green” their roof, as well as the environmental and economic savings that will result. In addition, we created a “seed slingshot bookmarklet” that users can use to “green” any web page on the internet and see the amount of savings that can come from going green.
We encouraged users to put pressure on city/national leadership to implement more green rooftops.
