The Dirty Truth About "Clean Diesel"

Automakers have worked hard to convince consumers that a new generation of "clean diesel" cars are far less polluting, but recent scandal reveals that diesel exhaust is filled with potentially deadly particulate matter. PM 2.5 particulate matter (smaller than 2.5 microns, or one-thirtieth the width of a human hair) allows carcinogens to penetrate deep into tissues and organs. Click here to read the news story.

EHHI's Report on Vehicle Exhaust

Particulate matter in vehicle exhaust is particularly dangerous to children and fetuses whose brains and bodies are rapidly developing. Most people assume that the U.S. Environmental Protection Agency is sufficiently protecting air quality by setting limits for chemicals released from vehicles, but these efforts are not enough to protect health.
Regulations limit only a small percentage of all chemicals that are emitted from vehicle engines.
