PA HB783

Amends Pennsylvania's Unfair Trade Practices and Consumer Protection Law to classify misleading environmental marketing claims and "greenwashing" as unlawful deceptive practices

Prohibits untruthful or deceptive "net zero claims" that fail to clearly identify covered emissions, distinguish between actual emission reductions versus offsets, or lack substantiation by company plans

Defines "paltering" as using truthful statements that create false impressions about environmental benefits, and "reputational advertising" as environmental claims designed to improve brand perception

Allows private lawsuits for environmental marketing violations without requiring proof of ascertainable financial loss, with potential recovery of up to three times actual damages plus attorney fees

Takes effect 60 days after enactment
