MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

NO x is a precursor for both ground level ozone and secondary PM 2.5 which are regulated under the National Ambient Air Quality Standards (NAAQS) because of their adverse effects on human health and the environment. Better catalysts and urea dosing systems can achieve high NOx conversion during lower temperature operation.

UNEP Report Calls for More Sophisticated Approach to Developing Biofuels; Limitations of Current LCA Studies

Green Car Congress

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. There is an obvious link between environmental impacts estimated by life-cycle impact assessments and water quality problems described at the regional scale. Source: “Assessing Biofuels”.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

One opportunity to reduce the cost of biofuels is to reduce the cost of bioenergy feedstock, which constitutes a large portion of operating costs, and increase the conversion efficiency from biomass to fuels. Such land conversion may disrupt any future potential for storing carbon in biomass and soil.

Automakers agree on common plug to recharge electric vehicles

Tony Karrer Delicious EVdriven

A 220 volt socket like on your water heater or dryer would be better, ad these typically have 40 or 50 amp circuits, so they can deliver 8,000 to 10,000 watts - is this what they mean? Nuclear waste is a problem much harder to solve than CO2, and dams have quite an impact in the environment. In a word, no.
