LADOT launches $17.8M universal basic mobility pilot; e-bikes, shared EVs and on-demand EV shuttle

Green Car Congress

The LA Department of Transportation (LADOT) launched its Universal Basic Mobility (UBM) Pilot in South Los Angeles—one of the largest programs of its kind in the country, increasing access to transportation options for thousands of Angelenos. The Pilot is currently supported by $17.8 million in state and city funding.

NOAA study: Increase in stratospheric aerosols has offset some recent climate warming

Green Car Congress

A recent increase in the abundance of particles high in the atmosphere has offset about a third of the current climate warming influence of CO 2 change during the past decade, according to a new study led by NOAA and published in the online edition of Science. The increase in aerosols since 2000 implies a cooling effect of about 0.1

MIT report finds China’s actions on climate change crucial; argues for global economy-wide greenhouse gas tax

Green Car Congress

The report—titled “The Role of China in Mitigating Climate Change” and published in the journal Energy Economics , compares the impact of a stringent emissions reduction policy with and without China’s participation. From 2000 to 2010, China’s energy use grew 130%, up from a growth of 50% the previous decade.

Columbia team organizes available scientific evidence on the effects of air pollution on children’s health

Green Car Congress

Researchers at Columbia University, with colleagues at Boston University and Abt Associates, have identified concentration-response (C-R) functions for a number of adverse health outcomes in children associated with air pollutants largely from fossil fuel combustion. A paper on their work is published in journal Environmental Research.

Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?2050. Shipping-induced global temperature change in 2050 using different parameterizations of Indirect Aerosol Effect (IAE).

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University. —Newell and Raimi.
