Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

According to the EIA , “the plants that are the source of biomass for energy capture almost the same amount of CO 2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.” Therefore, biomass as energy source was assumed to produce no additional carbon emission.

Hawaii to get hydrogen fueling station; Toyota Mirai leases to follow

Green Car Reports

Tropical islands are some of the best places on earth to pioneer carbon-free energy and zero-emission vehicles. Within the United States, the eight islands of Hawaii are blessed with a temperate climate, abundant sunshine, few high-speed highways, and a statewide speed limit of 60 mph, achievable only on a few roads.

ICCT report quantifies emissions benefits if 12 states & DC adopt slate of California medium- and heavy-duty vehicle regulations

Green Car Congress

The 12 states and DC —along with California and Hawaii—signed a memorandum of understanding (MOU) calling for them to work toward a goal that 100% of new medium-duty (MD) and heavy-duty (HD) truck and bus sales will be zero emission by 2050, with an interim target of 30% by 2030.

Berkeley Lab/U. Hawaii team provides direct experimental evidence for mechanism for PAH formation in combustion; cleaner fuels could result

Green Car Congress

Researchers at the Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) and the University of Hawaii have provided direct experimental evidence for the validity of a proposed mechanism for the first step in the process that transforms gas-phase molecules into solid particles such as soot and other carbon-based compounds.

Study: annual climate impact of wild pigs could be greater than 1.1M cars

Green Car Congress

By uprooting carbon trapped in soil, wild pigs (feral swine), are releasing around 4.9 million metric tonnes of carbon dioxide annually across the globe, the equivalent of 1.1 When soils are disturbed from humans ploughing a field or, in this case, from wild animals uprooting, carbon is released into the atmosphere.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

The researchers say that their findings, recently published in an open-access paper in the journal Science Advances , are key to understanding how the universe evolved with the growth of carbon compounds. That insight could also help the car industry make cleaner combustion engines. Zhao et al.

NREL releases comprehensive vision for deep decarbonization of transportation

Green Car Congress

The transportation sector is the largest source of greenhouse gas emissions in the United States, accounting for about 28% of total carbon emissions. Like bioenergy, hydrogen sits at the center of NREL’s strategy for a transportation system decoupled from carbon emissions.
