The most populous state is also the biggest U.S. alternative energy market, and its environmental standards including car pollution rules and green building regulations are models for national and international policies.
The state aims to cut greenhouse gas emissions that cause global warming to 1990 levels by 2020, and the governor has also called for the state to reduce carbon emissions to 80 percent below 1990 levels by the year 2050.
"What they have proposed is a job killer," he said of the bill. "It also would give us a limited chance of reaching this goal (for cutting greenhouse gases). It also would raise rates and is protectionism to the highest level," the governor said in webcast remarks after signing the bill. He will veto the legislature's plan.
The executive order puts the state's Air Resources Board in charge of implementing the 33 percent standard and it could develop detailed guidelines by the middle of next year.
Public Utilities Commission Deputy Director Nancy Ryan said that the commission aimed to keep the expansion of renewable energy "simple, flexible and workable."
"Unfortunately, the legislation was highly proscriptive and overly complex," Ryan said.
Some industry groups and renewable energy companies, such as Tempe, Arizona-based First Solar Inc had lined up in favor of the legislation and urged the governor to sign the bills.
