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

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

EPA proposes tightening primary ozone standards to range of 65-70 ppb; final rule by October 2015

Green Car Congress

Counties where measured ozone is above proposed range of standards, based on 2011-2013 monitoring data. Earlier this year, EPA staff had recommended the further reduction of this primary ozone standard from the current 75 ppb (parts per billion) to a revised level within the range of 70 ppb to 60 ppb—and preferably below 70 ppb.

California 2017 GHG inventory shows 1.2% total drop from 2016; transportation sector emissions up 1%

Green Car Congress

The transportation sector remains the largest source of GHG emissions in the state, and saw a 1% increase in emissions in 2017. Transportation sector emission sources include combustion of fuels utilized in-state that are used by on-road and off-road vehicles, aviation, rail, and water-borne vehicles, as well as a few other smaller sources.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. Another important component of emissions is volatile organic compounds (VOCs), a broad classification of carbon-based molecules that are easily vaporized and that can contribute to ozone formation.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Shown in the bottom row are sales data of fuels for mobile sources (from Fig. 1A) and sales data of volatile chemical products.
