UCS: ride-hailing trips can produce nearly 70% greater emissions compared to private car trips

Green Car Congress

A new report by the Union of Concerned Scientists (UCS) finds that the rising use of ride-hailing services is increasing carbon emissions, with ride-hailing trips producing nearly 70% greater emissions compared to the trips they are replacing. Error bars for bus and rail emissions represent variability among cities. Source: UCS.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. That swirling mass of matter would eventually give shape to the earliest forms of carbon—precursors to molecules some scientists say are connected to the synthesis of the earliest forms of life on Earth. Zhao et al. PAHs have a dark side, too.

Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. A key control strategy is to reduce emissions of the limiting reagent.

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable. The Flameless Ceramic Turbine combines flameless combustion technology and innovations in ceramic design to deliver demand-responsive power without the emissions.

WHO: 9 out of 10 people worldwide breathe polluted air; 7M deaths per year

Green Car Congress

New data from the World Health Organization (WHO) shows that 9 out of 10 people breathe air containing high levels of pollutants. Updated estimations reveal a death toll of 7 million people every year caused by ambient (outdoor) and household air pollution. Ambient air pollution alone caused some 4.2 g/m 3 (for PM 10 ) and 10 ?g/m
