The modeled 2028 base year 8-hour ozone design values were found to be above the 70 ppb NAAQS for 75 monitoring locations. By 2035, 46 states will be in attainment with the 2015 ozone NAAQS of 70 ppb (only counties in California and Utah remain in nonattainment). Source: MECA. ppb in the west (San Bernardino, CA) and 4.9
(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.
BASF has launched UpCore, a new service providing a cost-effective and sustainable technology upgrade from a standard ozone converter to an ozone-VOC (volatile organic compounds) converter for cleaner and healthier aircraft cabin air. The air at high altitude contains significant levels of ozone.
The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. It is estimated that heavy-duty trucks will be responsible for one-third of NO x emissions from the transportation sector in 2025.
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.
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.
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.
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.,
One of the more lasting contributions we can make in our community is to protect the environment by reducing ozone-forming emissions wherever possible. These trucks run cleaner and quieter, and will help to make the local environment healthier for future generations.
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.
The processes that create ozone pollution 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. Regulations and cleaner technologies have steadily improved air quality in the United States.
For heavy-duty vehicles, the State SIP Strategy calls for combustion engine technology that is effectively 90% cleaner than today’s standards. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. emissions by more than 20%.
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.
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. grams per brake horsepower-hour (g/bhp-hr). Earlier post.). g/bhp-hr heavy-duty engine standard.
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 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.
Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.
The US EPA issued an Advance Notice of Proposed Rulemaking (ANPR) for the Cleaner Trucks Initiative (CTI). The EPA Administrator announced in November 2018 that EPA would pursue the Cleaner Trucks Initiative (CTI) to update NO x emissions standards for heavy-duty trucks. EPA is seeking input from the public and interested stakeholders.
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.
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.
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. Improving Air Quality.
More findings from the CalNex research on a variety of subjects, from the formation of ozone to the interactions of particles and clouds, are being presented at a four-day workshop May 16 through 19 in Sacramento, California.
However, it needs to be combined with subsidies for switching to cleaner heating options for low-income households. Wealthier regions, including large cities, tend to have on average higher levels of nitrogen dioxide (NO 2 ), mostly because of the high concentration of road traffic and economic activities.
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.
in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol. 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.
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.
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 researchers used tropospheric NO 2 columns retrieved from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, which measures NO 2 throughout the atmosphere in the afternoon around the world. Despite large populations, Indian cities seem cleaner in terms of NO 2 pollution than the study’s other regions.
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.

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.
The regulation sets a statewide limit on sources responsible for 85% of California’s greenhouse gas emissions and establishes a price signal needed to drive long-term investment in cleaner fuels and more efficient use of energy. 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.
In addition to ozone and particulate matter, the other pollutants are lead, carbon monoxide, nitrogen dioxide and sulfur dioxide. The authors emphasized that their findings do not specifically address an individual’s health risk or the personal benefits of cleaner air, but rather assess population level health impacts.
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.
Coloradans want low- and zero-emissions vehicles because they help them get where they’re going while breathing cleaner air and saving money. “Colorado is already among the states with the highest concentration of electric vehicles, and we don’t plan on hitting the brakes any time soon,” Commission Director Michael Ogletree said.
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.
And the grid is getting cleaner and more renewable every year. 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.
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.
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). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).
