On 23 October 2015, the Southern California Gas Company discovered a methane leak at its Aliso Canyon natural gas storage facility, some 80 kilometres from downtown Los Angeles. It was a big one, quite possibly the largest leak in US history. Day after day, Aliso Canyon was releasing carbon emissions equivalent to those produced by 4.5 million cars, more than doubling emissions for the entire Los Angeles area. It took until February for the leak to be finally plugged.
‘It’s the climate equivalent of the BP disaster in the Gulf of Mexico,’ The Guardian reported.
