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.

Study finds drone-based delivery could reduce GHG emissions and energy use in the transportation sector, if deployed sensibly

Green Car Congress

New research by Lawrence Livermore National Laboratory (LLNL), Carnegie Mellon University, SRI International and the University of Colorado at Boulder shows that drone-based delivery could reduce greenhouse gas emissions and energy use in the transportation sector. An open-access paper on the research appears in Nature Communications.

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.
