The bill establishes a limitation on civil and criminal liability for any alleged actual or potential effects on climate resulting from greenhouse gas emissions. It defines key terms such as "agricultural source," "greenhouse gas," and "renewable fuel source," and specifies that greenhouse gases include various specific gases like carbon dioxide, methane, and nitrous oxide. Under the new provisions, a defendant cannot be held liable for damages or injuries related to climate effects unless the plaintiff can provide clear and convincing evidence that the defendant violated specific statutory limitations or permit terms related to greenhouse gas emissions.

Additionally, the bill clarifies that its provisions do not create a right to initiate civil or criminal actions based on the potential climate effects of greenhouse gas emissions. The court must find substantial evidence of a violation of enforceable regulations or permits before liability can be established. This legislation aims to protect defendants from legal actions that allege climate-related damages unless stringent criteria are met.
