The California Air Resources Board approved changes to an existing $28 million financial assistance program this week that will significantly help more California independent truckers qualify for the purchase of a cleaner-running vehicle.
Alternative-fuel technology company ROUSH CleanTech has developed the first available propane autogas engine certified to California Air Resources Board’s (CARB’s) optional low oxides of nitrogen emissions standard for heavy-duty engines with 0.02 The engine is 90% cleaner than the current Environmental Protection Agency’s most stringent 0.2
The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. As transportation gets cleaner, those other sources become more and more important. —Brian McDonald, corresponding author.
Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.
A longer service life reduces the fleet’s turnover rate to cleaner, lower-emitting engines, therefore increasing future-year emission estimates. The US Army Corps of Engineers estimates that, as of 2014, there were approximately 9,000 Category 1 and 2 marine vessels operating on US waters.
Improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO 2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions. Achakulwisut et al.
The Green Aviation Summit is highlighting the depth and breadth of NASA’s work to develop aviation technologies that are designed to make air transportation cleaner and quieter for the environment, with fewer delays for travelers. ” —Ames Research Center Director Simon “Pete” Worden.
In a separate action, the California Energy Commission approved $4,979,070 through the current ARFVT program to projects that will support increased numbers of cleaner, alternative fuel vehicles on California roadways. Buyers are required to register and operate the vehicles in California at least 90 percent of the time for three years.
g/bhp-hr, which is 90% cleaner than EPA’s current NO x emission standard and 90% cleaner than the cleanest available diesel engine. NO x emissions lead to the formation of ozone and small particulate matter (PM 2.5 ), each of which contributes to significant health impacts, including asthma and heart disease.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. Damages from electricity generation.
On their 100+ mile round trip, these trucks burn diesel fuel that damages the ozone, spews out noxious particulates that seek-out lungs and eyes along with oxides of nitrogen that help create smog, along with other nasty—and toxic—unpleasantness. How much cleaner could the air be if, instead of 50 trucks, it is 500, 1,000 or 10,000.
Earlier ACES reports (available at ) found substantial reductions in particulate matter and other pollutants in the emissions from both 2007 and 2010 engines. Countries like China are already moving toward implementing the ultra-low sulfur diesel fuel that is required for these new cleaner technologies.
Although generalized mass fractions are available for non-exhaust and exhaust road transport PM emissions, the regional, spatial, and temporal patterns of the former are least known, while the role of suspension versus primary wear emissions is even less characterized.
Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.
Im gonna post a couple excerpts here: Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog). (7, like i said in the first place, for me, this makes me think of one step in the right direction and makes me think of a greener cleaner future.
Rebates are available to individuals, business owners and government entities in California that purchase or lease new eligible zero-emission or plug-in hybrid electric light-duty vehicles now. The amount of funding available to pay for these technologies is dependent on the amount of revenues generated from vehicle and smog abatement fees.
Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Since its launch in 2011, the regulation has generated a multitude of unique approaches for cleaner fuels. In 2014 ARB will consider extending the LCFS, with more aggressive targets for 2030.
