Short summary
Reducing methane emissions from the oil/gas sector can mitigate near-term climate warming and the losses of a valuable energy resource. We analyze data collected using MethaneAIR to assess methane emissions in regions accounting for 70 % of United States onshore oil/gas production in 2023. We estimate total oil/gas methane emissions across all measured regions to be ~8 Tg/yr, equivalent to 1.6 % of produced gas, which is five times higher than reported by the US Environmental Protection Agency.
