Video: CO2 maps zoom in on greenhouse gas sources

'Revolutionary' CO2 maps zoom in on greenhouse gas sources. A new, high resolution, interactive map of United States 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, in the best cases, monthly at the level of an entire state grid.

The Vulcan model examines CO2 emissions at local levels on an hourly basis. Purdue researchers say the maps are also more accurate than previous data because they are based on greenhouse gas emissions instead of estimates based on population in areas of the United States.
