Methane leaking from pipes before natural gas is delivered to customers can have a large, harmful impact on the climate. This idea was first brought to light in a major scientific paper published in 2012, and supported by numerous papers since. For California, a climate leader, and a state that consumes 10 percent of the nation’s natural gas supply – this leakage epiphany was and continues to be a very big deal.
Last week, after years of science, politics, and policy deliberations, the state took one of its boldest steps yet in the quest to cut methane escaping from its vast network of aging pipes underneath city streets – a move that should result in a new direction for California, and likely for utilities across the nation.
That move, taking the form of a 28-page report and staff recommendations from California Public Utilities Commission (CPUC) as part of the implementation of a 2014 law (SB 1371), proposes to require utilities in California to use specific best practices to find, fix, and prevent leaks from the natural gas distribution system.
