(Japan) report in the journal Angewandte Chemie the development of a mesoporous two-line ferrihydrite (2LFh)—ferrihydrite is a widespread mineral composed of iron, oxygen, and water—that could lead to a new generation of ozone filters in electrostatic devices and aircraft applications. removal; it showed about 95 % O 3.
Five technology paths for very-low-NO x and GHG emissions from heavy-duty natural gas engines. The “Pathways to Near-Zero-Emission Natural Gas Heavy Duty Vehicles” report, authored by GNA on behalf of Southern California Gas Co. Click to enlarge. Click to enlarge. Background. Click to enlarge.
has brought 67 Compressed Natural Gas (CNG) solid waste and recycling trucks to serve customers throughout southern New Jersey and in Philadelphia. One of the more lasting contributions we can make in our community is to protect the environment by reducing ozone-forming emissions wherever possible.
VOCs, primarily emitted from the tailpipes of vehicles, are a key ingredient in the formation of ground-level ozone which, at high levels, can harm people’s lungs and damage crops and other plants. The reason is simple: cars are getting cleaner. —lead author Carsten Warneke, Ph.D.,
Widespread adoption of electric transportation, including electrification in the off-road sector, could lead to substantial reductions in greenhouse gas (GHG) emissions and could modestly improve air quality, according to a new analysis released by the Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC).
The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants. For heavy-duty vehicles, the State SIP Strategy calls for combustion engine technology that is effectively 90% cleaner than today’s standards.
The program funds projects to encourage the development and use of new technologies and alternative and renewable fuels, including electricity, natural gas, biomethane, hydrogen, and gasoline and diesel substitutes, such as cellulosic ethanol (derived from woody materials, including agricultural waste), and biodiesel from waste grease.
The engine is 90% cleaner than the current Environmental Protection Agency’s most stringent 0.2 Last year, we introduced a propane autogas engine that was 75% cleaner than the EPA’s emissions standard. Cummins offers its own line of Near-Zero NO x engines running on natural gas. grams per brake horsepower-hour (g/bhp-hr).
The cap-and-trade program also works in concert with other measures, such as standards for cleaner vehicles, low-carbon fuels, renewable electricity and energy efficiency, and complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants. Click to enlarge.
Each of the four recipients will match a percentage of the grant amount with their own funds to purchase compressed natural gas-powered vehicles; retrofit diesel engines with cleaner technology; replace older, more polluting diesel buses with cleaner diesel buses; or purchase hybrid electric-powered buses.
Cummins Westport ISL G near-zero (NZ) natural gas engine ( earlier post ) meets and exceeds the certification standards during a full range of duty cycles. g/bhp-hr, which is 90% cleaner than EPA’s current NO x emission standard and 90% cleaner than the cleanest available diesel engine. liter equipped vehicle.
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. —Susan Anenberg.
Jackson said that EPA must follow up the progress it made in 2009 with a range of greenhouse gas reduction initiatives with ensuring compliance with the law. The seven themes are: Taking Action on Climate Change. Improving Air Quality.
California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. Per capita GHG emissions in California have dropped from a 2001 peak of 14.0 tons per person to 10.7 tons per person in 2018, a 24% decrease.
The downward emission trend of three main pollutants which cause ground-level ozone continued in 2007: carbon monoxide (CO) fell by 57%, non-methane volatile organic compounds (NMVOCs) were down by 47% and nitrogen oxides (NO x ) have dropped 36%. EU-27 emissions of all four pollutants were lower in 2007 than in 2006.
The California Air Resources Board on Thursday adopted the final greenhouse gas (GHG) emissions cap-and-trade regulation. Compliance obligations for greenhouse gas emissions begins 1 January 2013. the second, starting in 2015, brings in distributors of transportation fuels, natural gas and other fuels. Earlier post.)
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. Most vehicle and fuel combinations had similar levels of greenhouse gas emissions in 2005.
The approach described is designed to meet simultaneously federal air quality standards; achieve greenhouse gas emission reduction targets; reduce petroleum consumption; and decrease health risk from transportation sources through 2030. Under current control programs (left) and under the Cleaner Technologies and Fuels scenario (right).
A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. national ambient air quality standards (NAAQS).

FTA’s Low-No Program supports transit agencies in purchasing or leasing low- or no-emission buses and other transit vehicles that use technologies such as battery electric and fuel-cell power to provide cleaner, more efficient transit service in communities across the country.
The California Air Resources Board released its proposed greenhouse gas cap-and-trade regulation. A key part of ARB’s AB 32 Scoping Plan ( earlier post ), the cap-and-trade program provides an overall limit on the emissions from sources responsible for 85% of California’s greenhouse gas emissions. Offset Protocols.
While current state and federal measures are on target to reduce toxic diesel locomotive emissions 65% or more by 2020, additional measures recommended by ARB staff would ultimately provide up to 85% or greater emissions reductions within the rail yards over the same period, resulting in cleaner air for nearby residential neighborhoods as well.
The major sources of methane in California are livestock (~30% of the state’s methane emissions), followed by landfills and oil and gas production. Methane is 72 times more efficient at trapping heat in the atmosphere than CO 2 , which is the most prevalent global warming gas. CO 2 remains in the atmosphere for up to a century.
Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). Chester and Horvath (2009).
The basic question addressed, which appears on the study homepage (epri-reports.org) is this: How would air quality and greenhouse gas emissions be affected if significant numbers of Americans drove cars that were fueled by the power grid? And the grid is getting cleaner and more renewable every year.
The state has also said that it’s aiming to get one million zero-emission vehicles on its roads by 2030, along with its plan to eliminate greenhouse gas pollution entirely by 2050. Coloradans want low- and zero-emissions vehicles because they help them get where they’re going while breathing cleaner air and saving money.
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.
Almost half the new buses are fueled by cleaner-burning propane or compressed natural gas; the others are cleaner-burning diesel engines. Nitrogen oxides and sulfur dioxides are precursor chemicals that, combined with sunlight, create ground-level ozone. Net-zero carbon emissions by 2050 are the governor’s goal.
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.
This SAE spec would make it so you could go to a gas station and they would have the proper voltage and plug for your car. but its never even been close to the amount of garbage that gas power vehicles produce. This would be like all laptop makers agreeing on the same plug to fit in all laptops. excluding coal power in china.
million to fund air quality improvement programs that will pay for cleaner equipment such as hybrid truck and buses, zero-emission and plug-in hybrid cars, and motorcycles. Cleaner vehicles reduce California smog and climate change emissions, and save consumers money. ARB was appropriated approximately $42.3
The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. Since its launch in 2011, the regulation has generated a multitude of unique approaches for cleaner fuels.
