Abate Particulate Matter emissions from engine exhaust by more than 90% in 5 years.
Combustion engines emit respirable PAH* exhaust particles of < 2.5 microns**.
Earth's gravity cannot ground these fine particles
Fine particles in the atmosphere cause smog & skewed rainfall distribution
Results in drought & floods
2 Million Deaths Each Year linked to Particulate Matter inhalation
*PAH = Polycyclic Aromatic Hydrocarbons, which are allergens and carcinogens
**1/20 the width of human hair
