California ARB study finds commuters’ exposures to air pollution greatly depends on mode of travel; light rail, personal vehicles the lowest

Green Car Congress

The researchers found that electricity-powered light rail trains offer the least polluted travel environment followed by personal vehicles, while commute trips by older technology diesel-powered trains experienced the highest average air pollution levels in Sacramento. These new technologies reduce particle emissions by about 90%.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

As with the earlier assessment, this study consists of two separate, but related, analyses: greenhouse gas emissions from 2015-2050, and air quality impacts in 2030. The report finds that greenhouse gas emissions from light-duty vehicles could drop as much as 64% below today’s levels.

EC JRC report explores future of road transport; moving away from system centered on private car ownership

Green Car Congress

Improvements in governance and the development of innovative mobility solutions will be crucial to ensure that the future of transport is cleaner, safer and more equitable than its car-centerd present. Between 1995 and 2015, the total number of passenger kilometers (pkm) in the EU-28 increased by 23.8 % to 6,602 billion.

California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The state’s latest Greenhouse Gas Emissions Inventory shows that California emitted 429 million metric tons of climate pollutants in 2016—a drop of 12 million metric tons, or three percent, from 2015. They fell 23% from a peak of 14 metric tons per person (roughly equal to driving 34,000 miles) in 2001 to 10.8

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The study examined utility meter readings of 130,000 households—a 1-in-10 random sample of all households in Singapore—from 2012 to 2015. Cleaner urban air will reduce energy demand, as households engage in less defensive behavior, and this helps to mitigate carbon emissions. —Prof Salvo.
