Groundbreaking Data Release Sheds Light on U.S. CO2 Emissions
In a significant advancement for climate research, Northern Arizona University has unveiled comprehensive data on carbon dioxide emissions across the United States covering the years 2010 to 2022. Spearheaded by Professor Kevin Gurney from NAU’s School of Informatics, Computing, and Cyber Systems, this initiative promises to deliver crucial insights into the nation’s carbon footprint.
The recent publication in Scientific Data marks the first in a series of data releases, offering a detailed database of 13 years of emissions data. Subsequent releases will delve deeper, providing specifics on emissions at neighborhood and city levels, vehicular emissions by road segment, and emissions from industrial facilities.
According to Gurney, a notable expert in atmospheric science, ecology, and public policy, the primary objective of this data release is to empower businesses, cities, and communities with the information needed to make informed environmental policy decisions. He stated, “The U.S. taxpayers have a right to this data,” emphasizing the importance of transparency, especially amidst potential policy changes like the proposed rule to cease the EPA’s greenhouse gas reporting program.
For over two decades, Gurney and his team have meticulously developed detailed maps of CO2 emissions, culminating in the latest release of the Vulcan system’s fourth version. This system captures emissions data from coal, oil, and natural gas combustion, pinpointed to specific times and locations where these fuels are consumed.
The Vulcan system’s latest output, as described by Pawlok Dass, a research associate involved in the project, comprises vast terabytes of data requiring robust computing power to process. “It captures CO2 emissions at unprecedented resolution—down to every city block, road segment and individual factory or power plant,” Dass noted.
Despite challenges such as funding cuts, highlighted in The New York Times’ “Lost Science” series, Gurney remains steadfast in his commitment to making this data accessible to the public. “We all remain committed to this research,” echoed Bilal Aslam, a Ph.D. student contributing to the emissions study, urging policymakers to utilize the data for climate-friendly investments.
Through projects like Vulcan and Hestia, funded by various federal agencies, Gurney aims to visualize greenhouse gas emissions across the country. By pinpointing emissions down to individual power plants and roadways, these projects facilitate targeted strategies for reducing emissions. Gurney’s work, recognized for its accuracy in comparison to direct atmospheric monitoring, is a cornerstone in global climate initiatives, including contributions to the United Nations Climate Change Framework Convention and the Kyoto Protocol.
