A new, high-resolution, interactive map of US carbon dioxide emissions from fossil fuels has found that the emissions aren't all where we thought.

The maps and system, called Vulcan, show CO2 emissions at more than 100 times more detail than was available before.

Until now, data on carbon dioxide emissions were reported monthly at the level of an entire state. The Vulcan model examines CO2 emissions at local levels on an hourly basis.
