Study finds paved surfaces in Houston worsen air quality

Green Car Congress

Houston, with a mix of petrochemical facilities, sprawling suburbs, and traffic jams that stretch for miles, has some of the highest levels of ground-level ozone and other air pollutants in the United States. The article is in press in the Journal of Geophysical Research-Atmospheres , a publication of the American Geophysical Union.

UNEP Report Calls for More Sophisticated Approach to Developing Biofuels; Limitations of Current LCA Studies

Green Car Congress

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. World ethanol production for transport fuel tripled between 2000 and 2007 from 17 billion to more than 52 billion liters (13.7 Source: “Assessing Biofuels”.

ICCT report finds global implementation of advanced emissions and fuel-quality regs could cut early deaths from vehicle emissions by 75% in 2030

Green Car Congress

Global trends in vehicle-kilometers traveled (VKT) and early deaths from vehicle-related fine particle exposure (2000–2030). Next-generation standards would target new reductions in emissions of NO x and non-methane hydrocarbons (HC), which are precursors to ozone and secondary particulate matter. Chambliss et al.

Researchers Engineer Yeast to Produce Methyl Halides from Biomass; Precursors for Biohydrocarbon Fuels

Green Car Congress

Methyl halides are naturally produced by a number of organisms; the enzyme responsible for this production—methyl halide transferase (MHT)—has been studied in the context of the environmental production of methyl halides, which contribute to ozone depletion. The second is the production of syngas by pyrolysis or microorganisms.

Im gonna post a couple excerpts here: Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog). (7, 1, 2000) Sited: [link] You can google it and find it anywhere that vehicles have always placed more harmful chemicals into the air.
