Study finds São Paulo switch from ethanol to gasoline dropped local ozone levels by 20%, increased CO and nitric oxide concentrations

Green Car Congress

A study by a pair of researchers at Northwestern University found that when fuel prices drove residents of São Paulo, Brazil, to switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20%. Ozone levels are relatively high in São Paulo, with hourly concentrations above 75 and 125 µg m ?3

EPA tightens ground-level ozone standard to 70 ppb

Green Car Congress

issued its final rule revising the National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb) from 75 ppb to protect public health. Ground-level ozone forms when nitrogen oxides (NO x ) and volatile organic compounds (VOCs) react in the air. The US Environmental Protection Agency (EPA).
