Study finds high-density, low-rise cities such as Paris may be optimal urban form for reducing life cycle GHG emissions

Green Car Congress

A study by researchers at CU Boulder and Edinburgh Napier University finds that high-density, low-rise environments such as those found in Paris are the optimal urban form when looking to reduce greenhouse gas emissions over their whole life cycle. There is a growing belief that building taller and denser is better.

New study finds gasoline stations vent up to 10x more benzene fumes than previously thought

Green Car Congress

A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses. However, residential uses and exports of natural gas were not considered in those comparisons.

TU Graz researchers identify singlet oxygen as major cause of deleterious side reactions in Li-air batteries; suggested approach to counter

Green Car Congress

Researchers led by a team from Graz University of Technology (TU Graz) in Austria have shown that singlet oxygen ( 1 O 2 ) forms in the cathode of a Li–O 2 battery during discharge and from the onset charge, and that it is responsible for a major fraction of side products that cause fast ageing in the battery.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

Improving the fuel efficiency of EVs from 20 kWh/100km to 14 kWh/100km, decreasing the share of coal-based electricity from 75% to 65%, increasing combustion efficiency of coal-fired power plants from 35% to 40%, and the new emission standard for new-build power plants will help reduce the PM emission of EVs.
