Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. gasoline demand would have put upward pressure on world oil prices.

Amyris renewable jet fuel receives regulatory approval in Brazil for blends up to 10%

Green Car Congress

Brazil’s fuels regulator, ANP, has cleared the way for the commercialization in Brazil of Amyris renewable jet fuel in blends of up to 10%. In the ES&T study base case, the researchers calculated a “rather optimistic” GHG footprint of 8.5g That paper is published in the ACS journal Environmental Science & Technology. Earlier post.).

Sandia study finds meeting RFS2 requirements unlikely without stronger enforcement mechanism; the importance of drop-in biofuels

Green Car Congress

The Sandia researchers showed that the key to meeting the RFS2 targets is the fuel price differential between E85 fuel and conventional gasoline (low ethanol blends), so that E85 owners refuel with E85 whenever possible. The Sandia study examines the set of circumstances under which the RFS2 mandate might be satisfied. Barter, Dawn K.

IIASA: removing fossil fuel subsidies will not reduce CO2 emissions as much as hoped

Green Car Congress

Removing fossil fuel subsidies would have only a small effect on CO 2 emissions and renewable energy use, according to a new study led by the International Institute for Applied Systems Analysis (IIASA) and published in the journal Nature. In addition, subsidy removal would not boost renewable energy use significantly, the team found.
