Researchers suggest that air quality tests need simplifying to help reduce dangerous emissions

Green Car Congress

The production of air pollution from motor vehicles, industrial power plants, and fossil fuel emissions are determined by complex chemical reactions. Stockwell, Emily Saunders, Wendy S. Goliff & Rosa M.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

California has already cut anthropogenic black carbon emissions by more than 90% since the 1960s, and existing measures are projected to cut mobile source emissions by 75% and total anthropogenic emissions by nearly 60% between 2000 and 2020. The SLCP Strategy is due to come before the Board for consideration in March 2017.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

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. Increased eutrophication is a key characteristic of biofuels from energy crops when compared with fossil fuels. of the world’s transport fuel. Source: “Assessing Biofuels”. Click to enlarge.

Researchers Engineer Yeast to Produce Methyl Halides from Biomass; Precursors for Biohydrocarbon Fuels

Green Car Congress

They can also be used as intermediates for the chemical synthesis of more complex carbon compounds such as fuel hydrocarbons. A method to convert biomass to methyl halides thus enables the transformation of biomass into drop-in chemicals and liquid fuels—e.g., cerevisiae for metabolism of toxic waste products.

Automakers agree on common plug to recharge electric vehicles

Tony Karrer Delicious EVdriven

@ Apr 19th 2009 4:54PM Or fuel cells (ex: hydrogen). By abstracting devices to use electricity as their fuel, we can concentrate on advancing clean electricity production techniques and have the benefits shared by everything. Nuclear waste is a problem much harder to solve than CO2, and dams have quite an impact in the environment.
