(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.
The processes that create ozonepollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. A key control strategy is to reduce emissions of the limiting reagent.
The European Community’s air pollutant emission inventory report released by the European Environment Agency finds that in 2007, sulphur oxides (SO x ) emissions were down by 72 % from 1990 levels. EU-27 emissions of all four pollutants were lower in 2007 than in 2006.
Today's electric cars already have a far lower lifecycle climate footprint than ICE cars, and in the future will also perform better on particulate matter pollution, rain acidification and ozone depletion The post EVs are 40 pct less polluting than ICE cars, and will be even cleaner by 2030 appeared first on The Driven.
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. Even so, lotions, paints and other products contribute about as much to air pollution as does the transportation sector.
Emissions from heavy-duty vehicles are primarily under the regulatory jurisdiction of state and federal government, and voluntary incentive programs are critical to transitioning fleets to the next generation of cleaner technologies and achieving reductions needed to meet air quality standards. standards.
A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. 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.
Cooking, cleaning and other routine household activities generate significant levels of volatile and particulate chemicals inside the average home, leading to indoor air quality levels on par with a polluted major city, according to a study by researchers at the University of Colorado Boulder. Earlier post.).
The US Environmental Protection Agency (EPA) has awarded $5 million to the Southern Alliance for Clean Energy (SACE) to help Southern truckers and small businesses to buy cleaner big rigs. About 8 million are exposed to air quality that violates the federal standards for particulate matter.
Data collected during a major 2010 state-federal atmospheric research project show that the first-in-the-nation regulation requiring ocean-going vessels to use clean fuel when near the California coast has been extremely effective in reducing sulfur dioxide pollution from ships, according to the California Air Resources Board (ARB).
CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. 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. emissions by more than 20%.
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).

In “Estimated Excess Morbidity and Mortality Caused by Air Pollution above ATS Recommended Standards, 2011-2013,” published online in the August edition of Annals of the American Thoracic Society , researchers report on the annual health benefits of meeting more protective standards recommended by the ATS for O 3 and PM 2.5.
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.
Use of electric vehicles would achieve greater reductions in GHG emissions, corresponding to the rate that the electric grid becomes cleaner, through greater reliance on renewables and low- and non-emitting generation. This research points to the importance of two fundamental and parallel trends in energy and the environment.
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.
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. CARB has approved additional measures to reduce emissions of greenhouse gases from super pollutants that must also be reduced significantly.
The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.
Eligible diesel emission reduction solutions include verified emission control technologies such as retrofit devices, cleaner fuels, and engine upgrades, verified idle reduction technologies, verified aerodynamic technologies and low rolling resistance tires, certified engine repowers, and/or vehicle or equipment replacement.
The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). The eventual CTI rulemaking will establish new, more stringent emission standards for NO x and other pollutants for highway heavy-duty engines. EPA is seeking input from the public and interested stakeholders.
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.
ABuilding on the proposed stronger ambient air quality standards for ozone ( earlier post ), EPA will develop a strategy for a cleaner and more efficient power sector, with strong emission reduction goals for SO 2 , NO x , mercury and other air toxics.
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.
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.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.

ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 Under current control programs (left) and under the Cleaner Technologies and Fuels scenario (right). Projected statewide light duty vehicle technology mix. Click to enlarge. Earlier post.).
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. Replacing older, high-polluting buses and vehicles with new CNG buses and vehicles can help reduce greenhouse gas emissions.
The program also complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants and improve energy efficiency in homes and businesses. the destruction of existing stores of ozone-depleting substances in the U.S.
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.
Simply put, the study found what advocates of electric transportation have long held to be true: as regards greenhouse gases and pollution generally speaking, the worst electricity is still better than petroleum. And the grid is getting cleaner and more renewable every year.
Inventorying criteria air pollutants showed that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 All components appear in the order they are shown in the legend.). Chester and Horvath (2009).

The Advanced Collaborative Emissions Study (ACES), released today by the Health Effects Institute (HEI), also confirmed that the concentrations of particulate matter and toxic air pollutants emitted from NTDE are more than 90% lower than emissions from traditional older diesel engines (TDE). Earlier post.)
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.
ARB staff reviewed four offset protocols and recommends that they be approved as part of this regulatory package: (1) the Urban Forest Projects Protocol; (2) the US Ozone Depleting Substances Projects Protocol; (3) the Livestock Manure (Digester) Projects Protocol; and (4) the US Forest Projects Protocol. Offset Protocols.
the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, they found that the two interventions had marginal effects on air pollution, because already implemented traffic policies will reduce PM 2.5 and EC by around 40% and 60% respectively, from 2010 to 2020. in Belgium. Hooftman et al. Hooftman et al.
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. tons of pollutant emission reductions and displacing more than 2.75
Volkswagen sold about 590,000 vehicles equipped with devices that defeated their pollution control features, leading to increased emissions of oxide. Almost half the new buses are fueled by cleaner-burning propane or compressed natural gas; the others are cleaner-burning diesel engines.
A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Researchers were able to track that data via a network of sensors around the Bay Area that monitor both CO2 and five critical air pollutants: carbon monoxide, nitrous oxides (NO and NO 2 ), ozone, and particulates (PM 2.5).
About 4 million children worldwide develop asthma each year because of inhaling nitrogen dioxide (NO 2 ) air pollution, according to an open-access study published in The Lancet Planetary Health by researchers at the George Washington University Milken Institute School of Public Health (Milken Institute SPH). —Susan Anenberg.
There is an exception to that in the category of what they call super pollutants, the very powerful but shorter-lived gases and chemicals that come from things like fertilizer production, methane. So those are really important, and those are a little bit different. And that was based on observations of volcanoes. They also mix with clouds.
The approximate linear relationship for each region is notable, suggesting that the dependence of urban NO 2 pollution upon population follows a power law scaling with population. Even though larger cities are typically more energy efficient with lower per-capita emissions, more people still translates to more pollution.)
Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. 10 ) of urban air, a fraction known to be enriched with non-tailpipe constituents.
A new report from the European Environment Agency (EEA) warns that the health of Europe’s most vulnerable citizens remains disproportionately affected by environmental hazards such as air and noise pollution and extreme temperatures, especially in Europe’s eastern and southern regions, despite overall improvements in Europe’s environmental quality.
The update identifies eight key sectors for ongoing action: Energy; Transportation, fuels, land use and infrastructure; Agriculture; Water; Waste management; Natural lands; Short-Lived Climate Pollutants (such as methane and black carbon); and Green Buildings. Transportation.
