| '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.
