Researchers Discover New Chemistry for Ozone Formation; Not Yet Monitored or Incorporated into Atmospheric Models

Green Car Congress

A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts per billion (ppb) of ozone; the current US Environmental Protection Agency (EPA) 8-hour average standard is 75 ppb.

UC Davis Begins $2.8M Studies on Impacts of Escaped Nitrogen

Green Car Congress

University of California, Davis researchers will receive $2.8 But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. Wastes from cattle, chickens and other livestock include nitrogen.

NC State Researchers Developing Ozonolysis Pretreatment for Energy Grass Feedstocks

Green Car Congress

Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components.

New Comprehensive Lifecycle Energy and Emissions Inventory Includes Non-Operational Components; Large Aircraft Can Perform Better than Light Rail

Green Car Congress

Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). Chester and Horvath (2009). Click to enlarge.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

In general, biofuels made from organic waste are environmentally more benign than those from energy crops. A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. However very few studies include water use impacts.

Here’s How We Could Brighten Clouds to Cool the Earth

Cars That Think

Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming. Such clouds might be less likely to produce rain, and the retained cloud water would keep albedo high. Our team, based at the.
