State lawmakers have set up a committee to study wildfire accountability.
The debate is coming in the wake of the worst wildfire season in state history.
Last fall, more than a dozen wildfires swept through wine country, killing 44 people and destroying nearly 9,000 structures.
An investigation blamed the Pacific Gas & Electric Co., which could now be on the hook for billions of dollars.
But PG&E says climate change must also be considered when assessing blame.
Potential changes to state law would only apply to future fires.
