Lowering the Temperature: Strategies for Cities
In an industrial area of Chicago, a new street actually eats pollution. Using titanium dioxide as an additive to ordinary cement, the road surface can actually destroy nitrous oxides at ground level. In addition, the lighter color of the cement reduces heat absorption during the day and lighting requirements at night. Chicago added rain absorbing bioswales planted with native species, high efficiency streetlights powered by solar and mini wind turbines to create what it calls the “greenest street in America.”

Speaking of trees, here’s a cool little video that lays out the myriad reasons we should be planting trees like crazy in our cities. Not just for their ability to cool us down or for their carbon absorption, but for their aesthetic and humanizing qualities as well.
