Aemetis closes $30M equity investment for biomethane pipelines and dairy digesters to produce below zero carbon renewable natural gas (RNG)

Green Car Congress

Dairies produce about 25% of California’s methane emissions and have become targets of carbon regulations aimed to reduce climate change. Our 60 million gallon ethanol plant is capable of using biogas to replace petroleum natural gas to produce a lower carbon biofuel and generate additional Low Carbon Fuel Standard credits.

Geologists discover new path to rare earth mineral formation; implications for green energy and tech industries

Green Car Congress

Their discovery has important economic implications because there are no substitute alternatives to these rare earth elements (REEs), which are indispensable due to their ability to form small and very powerful magnets essential for smart devices and low-carbon energy generation (e.g., Bayan Obo in 2006. 0c01313.

Peking University team develops method for modeling historical global black carbon emissions from motor vehicles with reduced uncertainty

Green Car Congress

Geographical distributions of global BC emissions from motor vehicles in 1976 (A) and 2006 (B). Country-based mean values are shown for 1976 and 1° × 1° resolution was used for 2006. Researchers at Peking University have developed a new methodology to model black carbon (BC) emissions from diesel and gasoline motor vehicles.

T&E study: Europe’s growing use of animal fats in fuels is becoming increasingly unsustainable; 8,800 dead pigs for Paris-NY flight

Green Car Congress

Europe’s growing use of animal fats to power its cars and planes is becoming increasingly unsustainable, according to a new study by Cerulogy funded by European NGO Transport & Environment (T&E). Use of animal fat biodiesel has doubled in the past decade and is 40 times higher than it was in 2006.
