SACRAMENTO, Calif. — California lawmakers on Wednesday pushed through an ambitious climate change package to further reduce the state’s carbon footprint and boost the use of renewable energy to 50 percent in 15 years.

The state Senate passed proposals to enact Gov. Jerry Brown’s call to curb greenhouse gas emissions by setting what the administration calls the most aggressive benchmark in North America over the objection of Republicans who characterized such regulation as coastal elitism that would kill working-class jobs.

California aims to boost statewide renewable electricity use to 50 percent, have drivers use half as much gasoline and make buildings twice as efficient under the proposal by Senate President Pro Tem Kevin de Leon, D-Los Angeles. His bill, SB350, advanced to the Assembly on a 24-14 vote.

“California has demonstrated our global climate leadership over the last decade,” de Leon said, adding, “These policies will further cement our leadership, further strengthen our economy while protect the health of our communities.”
