Cities around the world are joining forces in hopes of making it easier to fund and build climate-friendly urban spaces and infrastructure.

Investing in public transit, building efficiency and waste management in cities could be worth an estimated $17 trillion by 2050 in energy savings alone, according to the Global Commission on Climate and the Economy.

In Atlanta, Mayor Kasim Reed is overseeing the biggest expansion of public transit in the history of the city's system, the deployment of solar power on municipal buildings and the addition of electric vehicles to the city's fleet.

“So we're really moving on all fronts,” Reed said in an appearance at a summit on climate action in D.C. “The reason that we're here is to make sure that we're operating in a collaborative fashion, learning from the best people in this field, and then hopefully taking back real ideas so we can execute them a little bit faster in the city of Atlanta.”
