Declining Methane Emissions But Steady Leakage Rates Observed in Western U.S.

Methane emissions from the region have fallen by half, but analysis of leak rates show that there is still a ways to go in stopping methane leaks, which impact the climate and human health, and can impose costs on Utah’s economy.
