Search by county to see the level of smog pollution in the air. Smog can trigger asthma attacks and increase the risk of heart and lung diseases.

Despite clear evidence, EPA chooses to stop reconsidering indefensible, disappointing decision

The Clean Air Scientific Advisory Committee finds science ‘unequivocally’ shows current standards fail to protect public health and the environment

“Safe” levels of air pollution are unhealthy for many people new research shows. The EPA could change that.

A pesar de la creciente evidencia científica, la EPA propone protecciones de salud pública insuficientes

Groups applaud step, urge stronger protections against dangerous smog pollution

Earthjustice applauds EPA’s rethinking of particulate matter pollution rules

The air is easier to breathe today due to the protections provided by the Clean Air Act, but there are still over 130 million Americans living with areas that have dangerous levels of ozone pollution. Sometimes called smog, ozone is linked to premature deaths, damages plants and forests, and stunts tree and crop growth. Formed…

Fourteen health and environmental groups, half of them represented by Earthjustice, challenged ozone standards in a lawsuit in a federal appeals court.

Smog is choking our lungs and iconic wild places with dangerous brown haze

All areas of the country are legally entitled to healthy, clean air. Not all areas have it. Plaintiffs Center for Biological Diversity and Sierra Club bring this action for declaratory judgment and injunctive relief to compel Defendant Andrew R. Wheeler, in his official capacity as Administrator of the U.S. Environmental Protection Agency, to carry out his overdue legal obligation to officially determine whether certain moderate nonattainment areas of the country attained or did not attain the 2008 National Ambient Air Quality Standards for ozone by the statutory deadline, an action necessary to strengthen clean air protections so as to bring communities with unhealthy levels of ozone pollution into compliance with clean air standards by a new legal deadline.

Áreas que todavía poseen aire contaminado serán sujetas a protecciones más fuertes

Areas that still have dirty air will be subject to stronger protections
