California lawmakers voted to extend the state's climate change fighting efforts to 2030 on Wednesday, giving a new lease on life to the most ambitious greenhouse gas reduction program in the country.

The state Senate voted 25-13 in support of a bill that sets a target of cutting the state's output of heat-trapping emissions 40 percent below 1990 levels by 2030.

The state is currently on track to meet its 2020 goal of reducing emissions back to 1990 levels.
