A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

This brief note analyzes the changes in the price of gasoline during the first 13 weeks of 2020 and compares them with the changes during the first 13 weeks of 2019. The raw data (the average retail price of regular gasoline) came from the U.S. Indeed, during the same time period in 2019, gasoline prices increased by 20.3%.

Environmental impacts of gasoline and E85. In a similar way, the full breadth of impacts attributable to conventional gasoline production, such as natural resource consumption and hazardous pollutant emissions, must also be considered in order to make balanced comparisons to biofuels. Process flow diagrams for E85 and gasoline.

Comparison of current federal subsidy to base case assumptions showing lifetime fuel savings (HomeEve charging scenario). An EPA estimate based on the Chevy Volt’s reported efficiency is also included for comparison. In all cases, HEVs and PHEVs save gasoline over conventional vehicles. Earlier post.).

One high-efficiency combustion concept under investigation is gasoline compression ignition (GCI)—the use of gasoline-like fuels to deliver very low NO x and PM emissions as well as high efficiency in a diesel compression ignition engine. The commercially available gasoline base had an octane number of 87. Earlier post.)

A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.
