A new study of the recent methane leak in Aliso Canyon, California confirms that it was the largest methane leak in US history. According to the study, the disaster’s impact on the climate will be equivalent to the effect of annual greenhouse gas emissions from over half a million cars.
Last week at the oil industry gathering CERAweek, Reuters reported Environmental Protection Agency chief Gina McCarthy revealed that, “Methane emissions from existing sources in the oil and gas sector are substantially higher than we previously understood.”
Also last week, the Texas Observer reported that the combined methane leaks of the Barnett Shale gas fields was actually greater than the volume of the Aliso Canyon disaster — contributing 8% of nationwide methane emissions. And while the Aliso Canyon well has been capped, the Barnett shale emissions continue on.
