Northern Arizona University-led research in Environmental Research Letters compared 260 U.S. urban areas and found Climate TRACE's estimates averaged 70% below the Vulcan Project's.
Authors said Vulcan's on-road uncertainty is about 14%, making the gap significant for city-scale emissions tracking and policy use.
Climate TRACE co-founder Gavin McCormick disputed the findings, saying internal comparisons with official city datasets worldwide did not show the same pattern.
Is the world's most advanced emissions tracker leading city climate policies astray?
When AI climate trackers and official data disagree, how can cities plan their futures?
