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.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. Click to enlarge. Our study reveals that climate change and regional air pollution are intertwined problems. Kleeman of UC Davis, lead author.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. California’s vehicle GHG standards—authorized by AB 1493 (Pavley) in 2002, first approved in 2004, and extended in 2012—are delivering fuel consumption and CO 2 reductions.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

Automobile manufacturers were given tax breaks to produce cars that ran on hydrous ethanol, and, by 1980, every automobile company in Brazil was following this lead. By the mid-1980s, three quarters of the cars manufactured in Brazil were capable of running on sugarcane-based hydrous ethanol. 40 CFR § 80.27 Pursuant to 40 CFR § 80.27(a)(2):

Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

A new study led by researchers at the University of Michigan compared regulated and unregulated emissions from both light-duty passenger car (1.7 L/2004 calibration engines. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. L engine was operated under both 2004 and 2007 calibrations.
