OLYMPIA — Gov. Jay Inslee met Thursday with former California Gov. Jerry Brown to discuss climate issues, including a proposal for utilities to provide carbon-free electricity by 2045 that is working its way through the Washington Legislature. In September, Brown, a Democrat who left office last week as California’s longest-serving governor, signed legislation putting his state on the path toward all-clean energy electricity sources by the same date. Inslee said he invited Brown to Olympia to meet with several Democratic legislative leaders because of the “tremendous progress” on climate legislation in California. Inslee is among a crowded field of Democrats considering a 2020 presidential bid and looking for a legislative win on his climate agenda.
