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.

ORNL researchers use stop-light cameras to reduce fuel consumption of less-efficient vehicles via traffic management

Green Car Congress

Approximately 6 billion gallons of fuel are wasted in the US each year as vehicles wait at stop lights or sit in dense traffic with engines idling, according to US Department of Energy estimates. So, where to find a larger, fine-grained vehicle dataset? That was a bit of an effort, too, but that’s what it’s all about. —Thomas Karnowski.

NREL develops novel method to produce renewable acrylonitrile; carbon fibers from renewable biomass

Green Car Congress

Based on yields alone, this is a very important discovery: in comparison, after six decades of commercial-scale improvements and optimization, the traditional acrylonitrile production process achieves yields of approximately 80%–83%. Yet none have been able to compete with the traditional process in terms of cost and yield.
