Prop 45 fast-tracks polluting projects with less review, hiding risks to our air, water, and health. Corporations get fewer rules, while taxpayers pay the price. You deserve to know the risks. Vote NO on Prop 45.

Why are nurses, clean air advocates, and leading environmental organizations urging you to vote NO on Prop 45? Because they warn it could mean weaker protections for our air and water, more polluting projects fast-tracked with less review, and critical health risks hidden from communities. And when things go wrong? Families could be left paying the price. See why organizations like the Coalition for Clean Air and National Wildlife Federation OPPOSE Prop 45.

Who's spending millions to pass Prop 45? Corporate PACs funded by developers and utilities. What they're hiding: the pollution risks of projects built near your home. Prop 45 gives them fewer rules and bigger profits. It gives you less information and less say over what gets built in your community. Don't let them hide the risks. Vote NO on Prop 45.

Prop 45 would bring Trump's environmental agenda to California, fast-tracking polluting projects with less review while keeping the risks conveniently hidden from you. Great news if you're a polluter. Not so great if you're anyone else. Don't let Prop 45 bring Trump's agenda to California. Vote NO on Prop 45.
