Google’s New Tool to Fight Climate Change

Google has started estimating greenhouse-gas emissions for individual cities, part of what it recently described as an ambitious new plan to deploy its hoard of geographic information on the side of climate-concerned local leaders.

“The first step toward taking climate action is creating an emissions inventory,” says Saleem Van Groenou, a program manager at Google Earth. “Understanding your current situation at the city scale, and understanding what you can do to it—that’s an information problem, and that’s a good place for Google to sit.”
