Investigating problems and crafting solutions

Protecting the air we breathe. Every American should be able to breathe clean air. But smog pollution from power plants and vehicles puts the health of our children and families at risk. Our report, Trouble in the Air, shone a light on the smoggiest cities and counties across the country, and recommended solutions for cleaning up our air.


Educating the public and making our voices heard

Restoring the Chesapeake Bay to health. Pollution from factory farms and rampant development creates a dead zone in the Chesapeake Bay every summer where wildlife cannot survive—but a new EPA cleanup plan will set tough limits on big polluters. Our staff in Washington, D.C., Virginia and Maryland spoke to tens of thousands of people in the Chesapeake Bay area to build support for the plan, and are pushing state officials to join the EPA in enforcing strong pollution limits.
