Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

The data shows a slight increase in overall emissions from the previous year, and a slight decline in emissions from transportation, which is the state’s main source of both GHGs and air pollutants. Per capita GHG emissions in California have dropped from a 2001 peak of 14.0

I contributed the following to the World Wildlife Climate Witness site last week and it was published this morning. We’ve always planned on retiring and spending the rest of our lives right here, but these days we’re worried about what climate change is already doing – and about the far more serious consequences headed our way. In 2001 she terminated our grass lawns and replaced them with drought tolerant plants because of her concerns for water use.

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

The radiative forcing affects of a reduction in non-CO 2 pollutants (dominated by ozone and black carbon) can outweigh CO 2 effects, depending on the replacement energy source, according to a multi-pollutant study by researchers from the NASA Goddard Institute for Space Studies and the Environmental Defense Fund that examined the impact of a 50% reduction in on-road transportation emissions. Wang (2009) Climate forcing by the on-road transportation and power generation sectors.

The Greenius Goes Into Overdrive

As the climate change crisis goes from bad to worse (while the deniers get nuttier and more cult-like with each passing day) and Australia gives Californians an advanced sneak preview at what is without a doubt headed our way sooner than you expect , your Creative Greenius has only gotten more Fired Up, Ready to Go! In Manhattan Beach I’ve been watching the four committees of the ETF present their recommendations for the city council on water, waste, building and climate change.

Satellite study suggests California clean air regulations working to reduce PM2.5 emissions in state

Green Car Congress

pollution in the state. is especially burdensome in California and accounts for the greatest percentage of health impacts attributable to air pollution. species, was recently published in the journal Atmospheric Environment. The study demonstrates the success of California’s air pollution control programs, regulations, enforcement efforts and clean-air plans in regions with the greatest air quality challenges: Southern California and the southern Central Valley.

Motiv Power Systems delivering 7 electric walk-in vans to USPS as part of CARB program; deployment in Central Valley

Green Car Congress

Most of the immediate project benefits will accrue in the San Joaquin Valley, an economically disadvantaged area with some of the highest pollution burdens in the country, as evidenced by CalEnviroScreen scores within the worst five percent in the state. Since 2001, the USPS has operated 30 electric two-ton vehicles on the streets of New York City, and these were later joined by a pair of two-ton hybrid electric vehicles in Long Island.

ICCT: gap between official and real-world fuel economy figures in Europe reaches ~38%; call to implement WLTP ASAP

Green Car Congress

The data show that for private cars, the difference between on-road and official CO 2 values rose from around 8% in 2001 to 31% in 2013. The increasing gap also more than halves the official CO 2 reductions achieved during the last ten years, making it more challenging to meet the EU’s climate change mitigation objectives. Manufacturers measure vehicle fuel consumption in a controlled laboratory environment, using a test procedure called the New European Driving Cycle (NEDC).

Peking University team develops method for modeling historical global black carbon emissions from motor vehicles with reduced uncertainty

Green Car Congress

Black carbon is a key short-lived climate change forcer ( earlier post ) and motor vehicles are important sources of BC in the environment. A subsequent emission inventory for Asia estimated total BC emissions from on-road vehicles in this region alone to be 294 and 446 Gg in 2001 and 2006, respectively. There is also a potential of applying the quantitative approach developed in this study to other pollutants.
