Sentences with phrase «climate than gasoline»

Not exact matches

WASHINGTON — Biofuels made from the leftovers of harvested corn plants are worse than gasoline for global warming in the short term, a study shows, challenging the Obama administration's conclusions that they are a much cleaner oil alternative and will help combat climate change.

Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.

The current shift back to SUVs that guzzle much more petroleum than other cars, prompted by low gasoline prices, is a more worrisome sign for future climate change.

Currently the climate is that diesel powered vehicles and diesel fuel is more expensive than gasoline powered vehicles and gasoline which is not a winning combination to most American consumers.

Although corn ethanol as modeled here emits marginally less GHGs than does gasoline, the combined climate and air quality impacts are greater than those from gasoline vehicles.

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines.

He pointed to findings that corn ethanol, which plays the largest role in meeting RFS mandates, emits more greenhouse gases than gasoline, and he said it is «confusing» for the Obama administration to push corn ethanol while it seeks to lower global greenhouse gas emissions at the Paris climate summit.

Although diesel vehicles offer lower carbon dioxide emissions and higher gas mileage than gasoline vehicles, some expert scientists, like Stanford University Mark Jacobson, have argued that controlling diesel emissions could be the fastest and «most effective» way to slow climate change.

Jacobson's models, published in the Journal of Geophysical Research — Atmospheres, concluded that, even with stringent U.S. and European standards, diesel vehicles could warm the climate more over 100 years than gasoline - powered cars as a result of the relatively higher black carbon content of diesel.
