🚨 Prop 45 hides pollution risk from you. Vote NO.
Prop 45 undermines California’s bedrock environmental law, the California Environmental Quality Act, and would weaken protections for clean air and water.
The ballot measure would make it easier to fast-track environmentally destructive projects like highways, data centers and pipelines with less public oversight and accountability.
Sierra Club California and more than 400 tribal, public health, housing, environmental and labor organizations urge you to vote NO on Prop 45.
As the Trump Administration rolls back our federal environmental protections, it’s more important than ever to defend California’s public health and the environment.
