Oil and gas; prohibiting covered civil liability actions. Effective date.
SB 1439 blocks lawsuits against fossil fuel companies (including producers, sellers, and trade associations) that claim climate change or greenhouse gas emissions caused harm when their products functioned as designed. The bill prohibits any civil action seeking relief related to climate change, alleged climate effects, or emissions - covering common claims like fraud or failure to warn - but excludes cases involving violations of environmental or worker protection laws. It applies to all fossil fuels (oil, natural gas, coal, etc.) and requires courts to dismiss ongoing climate-related lawsuits immediately upon the bill's effective date. This law creates a new legal barrier for climate change litigation while preserving access to courts for environmental law enforcement.

MINOR
The bill was amended to explicitly include the purchase of fossil fuels for generating electricity within the scope of protected activities. This change ensures that entities buying fuel to power their operations are shielded from climate-related lawsuits alongside those who produce, manufacture, or sell the fuel.
Scope change
The scope of protection was expanded to cover the specific act of purchasing fossil fuels for electricity generation, which was previously not explicitly listed.
SCOPE
Added the phrase 'purchase for generation of electricity' to the list of protected activities regarding fossil fuels.
