Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. Benjamin Felzer, Lehigh University.

This is especially the case for those draining nitrogen-enriched urbanized and agricultural watersheds, highlighting the importance of managing nitrogen before it reaches open water. Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction.

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

Green Car Congress

Under the Proalcool Program, sugar companies were ordered to increase production and the state-run oil company, Petrobras, was required to make álcool (ethanol) available at its fuel stations. water content in it and Gasoline C, or E25, which is a mixture of 75% Gasoline A and 25% in volume of anhydrous ethanol (AEAC) with a maximum of 0.4%

Study finds paved surfaces in Houston worsen air quality

Green Car Congress

The international study could have implications for the air quality of fast-growing coastal cities in the United States and other mid-latitude regions overseas—the proliferation of strip malls, subdivisions, and other paved areas may interfere with breezes needed to clear away smog and other pollution.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). Dashed lines show US average emissions. Credit: ACS, Tessum et al.

COVID-19 Forced Us All to Experiment. What Have We Learned?

Cars That Think

At the same time, however, we can already measure solid improvements in productivity and innovation: Since February 2020, some 60 percent of firms in the United Kingdom and in Spain have adopted new digital technologies, and 40 percent of U.K. New businesses came into being at a faster rate in the United States than in previous years.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

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. In their paper on the impact of ethanol production on nutrient cycles and water quality, Simpson et al.
