IT Home reported on August 1 that the Environmental Defense Fund (EDF) released a report yesterday (July 31).The latest estimates show that 7.5 million tons of methane are leaked, flared and vented from onshore oil and gas facilities in the United States each year, four times the figure estimated by regulators.

Measurements also show that oil and gas producers are emitting methane into the atmosphere at a rate eight times higher than their advertised emissions targets.

Calculation method

The data was collected by MethaneAIR, a specially equipped jet aircraft that covers more than 70 percent of onshore oil and gas producing areas in the lower 48 states.

The MethaneAIR data comes from more than 30 flights conducted between June and October last year by a specially equipped jet leased by EDF.

MethaneAIR uses similar technology to MethaneSAT, a satellite developed by the Environmental Defense Fund that launched in March and is scheduled to begin providing public data later this year and become fully operational in early 2025.

Calculation results

The total emission rate observed in most areas of the 12 major production basins in the United States will reach 7.5 million tons per year, which is equivalent to about 8.6 tons per hour. IT Home attaches the relevant results as follows:

The 50 largest oil and gas companies, including BP, Shell and ExxonMobil, announced an emissions intensity target of 0.2% at last year's UN climate summit, but the latest test results show that the total methane loss rate in 12 basins is 1.6%, eight times that.
