Summary

Most natural gas leakage in Indianapolis likely originates from homes and other buildings, not exterior pipelines and large-scale distribution infrastructure that deliver the fossil fuel, according to Penn State researchers who assessed nearly a decade of data. Their observations could signal similar emissions patterns across U.S. cities and shape mitigation strategies, members of the team said. They evaluated continuous measurements of methane, the main component of natural gas, across the Midwest city to estimate emissions from natural gas distribution.
