California’s gas utilities have had their share of problems in recent years – so improvements in environmental impacts, operations, and safety are important to track.
In 2014, the California legislature passed a law to require utility companies to publicly disclose data on gas leaks and emissions while working to actually cut those emissions. Now, three years later, utility reporting has been standardized, an emissions trend has emerged, and the results are significant.
