California Governor Jerry Brown has signed landmark legislation - SB 350  - that establishes energy efficiency and renewable energy goals for California.

"California has taken groundbreaking steps to increase the efficiency of our cars, buildings and appliances and provide ever more renewable energy," said Governor Brown. "With SB 350, we deepen our commitment."

Governor Brown signed the legislation from the East Terrace of the Griffith Observatory overlooking the City of Los Angeles and was joined by dozens of government, climate, business, environmental justice and community leaders.

SB 350 codifies goals Governor Brown laid out in his January 2015 inaugural address to double the rate of energy efficiency savings in California buildings and generate 50% of the state's electricity from renewable sources by 2030.

The legislation is a step in the state's landmark plan to cut climate-warming pollution. It also establishes state policy to promote transportation electrification to meet the state's climate and clean air goals.

SB 350 builds on California's current 33 percent renewables portfolio standard, signed into law by Governor Brown in 2011.

Governor Brown first announced the goals codified in SB 350 in his inaugural address this year, in which he also committed to reduce today's petroleum use in cars and trucks by up to 50 percent within the next 15 years. Earlier this year, the Governor issued an executive order to reduce greenhouse gas emissions in California 40 percent below 1990 levels by 2030.

Additionally, as the clock ticks for national governments to reach a deal to reduce emissions ahead of the United Nations Climate Change Conference in Paris, Governor Brown continues to focus on building and broadening collaboration among cities, states and provinces, at the "subnational level."
