California ARB Seeks Further Reductions of Diesel Emissions at State Rail Yards

Green Car Congress

The 37 options were evaluated based on the following criteria: technical feasibility, potential emissions reductions, costs, and cost-effectiveness. Other measures may have potential, but are generally not as cost-effective. Total cost of those five measures is estimated to be $3.9

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. California’s vehicle GHG standards—authorized by AB 1493 (Pavley) in 2002, first approved in 2004, and extended in 2012—are delivering fuel consumption and CO 2 reductions.

UN Review of Recent Climate Research Concludes That Impacts Of Climate Change Coming Faster Than Anticipated

Green Car Congress

The developing and least-developed economies, 80% of the world’s population, accounted for 73% of the global growth of emissions in 2004. The hole in the ozone layer has had a cooling effect on Antarctica, and is partly responsible for masking expected warming on the continent. Global emissions were growing by 1.1%

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The first such vehicles were introduced by Volkswagen in 2003, and by 2004, they accounted for more than 17% of the Brazilian auto market. However, since the cost of the hydrous ethanol is significantly lower, hydrous ethanol will provide a lower cost per mile travelled, assuming the processing cost savings is passed on to the consumer.
