Purdue University press release: - A new, high- resolution interactive map of U.S. carbon dioxide emissions from fossil fuels has found that the emissions aren't all where we thought.
"For example, we've been attributing too many emissions to the northeastern United States, and it's looking like the southeastern U.S. is a much larger source than we had estimated previously.
"When you compare the old inventories to Vulcan, the new data show atmospheric CO2 differences that are as large as five parts per million in some U.S. regions in the late winter. The levels in the global atmosphere only rise one and a half part per million every year, so this is the equivalent of three years of global emissions in the atmosphere that isn't where we thought it was. This will be important for policy-makers and is enormous from a scientific point of view. It's shocking."
-- Kevin Gurney, Project leader and assistant professor of earth and atmospheric science at Purdue University.
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. The Vulcan model examines CO2 emissions at local levels on an hourly basis.
