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. Pomponi et al.

Los Angeles-Long Beach Port trucking company replacing entire diesel truck fleet with near-zero emissions natural gas trucks, RNG

Green Car Congress

(TTSI) is replacing its entire diesel trucking fleet with near-zero emission natural gas trucks, which it plans to fuel with carbon-negative renewable natural gas (RNG). TTSI’s 40 new near-zero emission heavy-duty compressed natural gas (CNG) trucks reduce this type of emissions by 90%. Southern California Gas Co.
