A paper today in the journal Science, estimating emissions from the massive methane leak at Aliso Canyon, indicates that nearly 100,000 metric tons of methane escaped into the atmosphere over Southern California – more than previous estimates. The new findings come days after the Environmental Protection Agency released draft results of their updated accounting of methane emissions from the nation’s oil and gas supply chain that shows that emissions are up 27% above the agency’s early estimate.

The more we know about methane emissions, the higher they get. The new findings show not just the massive scale of the oil and gas industry’s methane problem, but also how critical it is to get the science right to both understand this source of a potent climate pollutant and reduce it. We know that cutting methane is one of the fastest, most cost effective ways to curb today’s warming, and when combined with critical efforts to reduce carbon dioxide pollution, substantial climate progress can be made.

After more than four months of spewing potent methane pollution, the massive Aliso Canyon gas leak has finally been plugged. But now the state of California and the utility that owns the site, SoCalGas, are left with the responsibility of ensuring a disaster like this doesn’t happen again.

While Aliso Canyon has captured the attention of the nation, it’s important to remember that there are smaller—and far more prevalent—leaks happening throughout the country’s oil and gas supply chain every day. In fact, those emissions add up to more than 7 million metric tons of methane pollution every year.  That equals over $1 billion worth of wasted natural gas at 2015 prices. Read More »
