Klimaforscher findet große Fehler in einer globalen Datenbank zur Klimaverschmutzung

From the article:

„New research from Northern Arizona University found that a global greenhouse gas emissions database produced by the Climate TRACE consortium, co-founded by former Vice President Al Gore, is underestimating vehicle carbon dioxide emissions in cities by an average of 70%.

Today, professor Kevin Gurney of NAU’s School of Informatics, Computing, and Cyber Systems (SICCS) published results in Environmental Research Letters analyzing the carbon dioxide (CO2) emissions from cars and trucks in the recently released Climate TRACE database. He said these findings, combined with a previous study noting similar discrepancies at power plants, raise concerns because accurate and reliable information on greenhouse gas emissions is a critical ingredient for society’s response to climate change.

„Given the importance of vehicle CO2 emissions in cities, we carefully examined the Climate TRACE data which relied on promising new artificial intelligence-based approaches,“ Gurney said. „When combined with our previous study on Climate TRACE power plant CO2 emissions, our results suggest that the Climate TRACE data significantly underestimate over half of U.S. fossil fuel-based CO2 emissions in cities.“

Gurney and his team matched the Climate TRACE urban vehicle CO2 emissions in the United States to a similar „onroad“ database, Vulcan, produced by Gurney’s laboratory, which is calibrated to official traffic and energy consumption data.“
