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. Estimated attribution of fuel savings due to fuel economy improvements to light-duty vehicles since 1975.

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

Researchers at the University of Oxford have developed a method to convert CO 2 directly into aviation fuel using a novel, inexpensive iron-based catalyst. The conversion reaction also produces light olefins—ethylene, propylene, and butenes—totalling a yield of 8.7%. and selectivity to C 8 –C 16 hydrocarbons of 47.8%

EEA reports sharp decrease in CO2 emissions of new cars in Europe in 2020

Green Car Congress

2020 car registrations by fuel type in Europe. Since 2017, the new Worldwide Harmonized Light Vehicle Test Procedure (WLTP) has been put in place with the objective to gradually replace the outdated New European Driving Cycle (NEDC). This was 14.5 g (12%) lower than in 2019 and represented the first decrease observed since 2016.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. We hope that it can be a steppingstone for future sustainable solar fuel production.

New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. In past decades, many scientists have tried to develop artificial photosynthesis processes to turn carbon dioxide into carbon-neutral fuel. A paper on this team’s latest work was published in Nature Catalysis.

EPA trends report finds MY 2021 fuel economy remained flat at a record high while CO2 levels hit new low

Green Car Congress

The US Environmental Protection Agency (EPA) released its annual Automotive Trends Report , which shows that model year (MY) 2021 vehicle fuel economy remained at a record high—but flat with MY 2020 fuel economy—while CO 2 emission levels reached a new record low. Estimated real-world fuel economy and CO 2 emissions.
