Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. Atherosclerosis refers to the build-up of plaque, or fatty deposits, in the artery walls, which, over time, restricts blood flow through the arteries.
In a statement released this morning, President Barack Obama said he has requested that US Environmental Protection Agency (EPA) Administrator Lisa Jackson withdraw the agency’s draft Ozone National Ambient Air Quality Standards (NAAQS) rulemaking. Earlier post.) National Ambient Air Quality Standards (NAAQS).
Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.
The California Air Resources Board today approved a statewide plan for attaining the federal health-based standard for ozone, typically experienced as smog. The 2022 State Implementation Plan Strategy identifies the state’s control strategy for meeting the federal 70 parts per billion, 8-hour ozone standard over the next 15 years.
The proposed multi-pollutant rule would further reduce air pollution from heavy-duty engines and vehicles across the United States, including ozone and particulate matter (PM). This proposed rulemaking builds on and improves the existing emission control program for on-highway heavy-duty engines and vehicles.
Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new study by researchers at NOAA and their colleagues shows. —NOAA scientist Stephen Montzka, lead author of the paper.
It is not possible to build wind and PV plants everywhere. Researchers at the Fraunhofer IFF have teamed up with Anleg GmbH to build one of the subcomponents, the Mobile Modular H2 Port (MMH2P), a portable hydrogen filling station for short trips of up to 200 kilometers.
The plant builds the GMC Acadia and the Cadillac XT5 and XT6, as well as several engines. By moving the needle in the voluntary green power market, GM and other Green Power Partners are helping to reduce the negative health impacts of air emissions, including those related to ozone, fine particles, acid rain and regional haze.
BASF is investing approximately €90 million (US114 million) in the first step to build a mobile emissions catalysts production facility in ?roda In addition, the plant will house a regional sample laboratory and a production line for BASF’s Premair-branded ozone destruction catalysts for automotive applications. aw, Poland.

Neste Oil is building a system for recovering emissions released when loading ships at the harbor of its Porvoo (Finland) refinery. The latter form ozone in the lower atmosphere when they react with NO x in the presence of sunlight.
The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.
In order to maximize LoNo Program impact, FTA seeks to build on existing transit bus procurements, where possible. An Eligible Area for the awards is either: Designated as a non-attainment area for ozone or carbon monoxide under section 107(d) of the Clean Air Act (42 U.S.C. 7407(d)); or.
While they do not deplete the ozone layer, many are highly potent greenhouse gases whose use is growing rapidly as replacements for ozone-depleting substances being phased out under the Montreal Protocol. The Montreal Protocol was established in 1987 to protect the ozone layer.
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.
The project provides financial and other incentives for ocean-going vessels to reduce their speed in specified areas along the coast during peak ozone and migratory whale seasons. These reductions decrease air pollution and the mortality rate of endangered whales.
The project builds upon the idea that air quality and climate change issues are linked through “one atmosphere”, an approach that demands coordination and multi-tiered approaches. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs. CalNex is the culmination of three years’ preparation.
HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
Global ozone-depleting substances (ODSs) and HFC emissions (A), global CO 2 and HFC emissions (B), and ODS, HFC, and CO 2 global RF (C) for the period 2000–2050. These HFCs, gases used in refrigerators and air conditioners, are substitutes for ozone-depleting gases, but they are also strong greenhouse gases. Velders et al.
Clean Fuels grant recipients will be chosen through a competitive selection process based on their ability to help communities achieve or maintain the National Ambient Air Quality Standards for ozone and carbon monoxide, while supporting emerging clean fuel and advanced propulsion technologies for transit buses.
The report touts the accomplishments of Prime the Pump, a nonprofit organization dedicated to helping build the infrastructure and distribution of higher biofuel blends. The Prime the Pump market development campaign has: Doubled the number of E15 stations four years in a row to include 1,400 stations across 30 states.
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. Building Strong State and Tribal Partnerships. Improving Air Quality.
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. This includes ongoing implementation of the existing control program, combined with new regulatory measures identified in the State SIP Strategy. emissions by more than 20%.
A view of the inside of the CitiSense sensor: the three cylindrical components detect ozone, nitrogen dioxide and carbon monoxide. The CitiSense sensors detect ozone, nitrogen dioxide and carbon monoxide, the most common pollutants emitted by cars and trucks. —Nikzad et al. Click to enlarge.
Development of sustainable communities strategies can also provide an opportunity for associated criteria pollutant emission reductions that will be needed to attain air quality standards for ozone and particulate matter as well as reduce near-roadway exposures.
Specifically, the proposed rule updates the current prohibition under section 608 of the Clean Air Act against knowingly venting, releasing or disposing of ozone-depleting (ODS) and substitute refrigerants and extends the requirements, as appropriate, to non-ozone-depleting substitute refrigerants, such as hydrofluorocarbons (HFCs).
Researchers at the University of Toronto have found that natural sunlight triggers the release of smog-forming NO x compounds from the grime that typically coats buildings, statues and other outdoor surfaces in urban areas. Among these compounds are nitrogen oxides. —James Donaldson.
The solicitation is putting less emphasis on model building, and greater emphasis on predictability studies, such as those involving extreme events; prediction and attribution; upscaling/downscaling; and interactions between natural and human systems.

million for regional alternative fuel readiness and planning, building on previous projects supporting these efforts. $2 Currently, the state’s transportation sector accounts for nearly 40% of the state''s greenhouse gas emissions; more than 95% of all transportation energy consumed in California is petroleum-based.
Cap-and-trade is another important building block in California’s effort to create a clean and vibrant economy. the destruction of existing stores of ozone-depleting substances in the U.S. The program is designed to provide covered entities the flexibility to seek out and implement the lowest-cost options to reduce emissions.
Houston, with a mix of petrochemical facilities, sprawling suburbs, and traffic jams that stretch for miles, has some of the highest levels of ground-level ozone and other air pollutants in the United States. The article is in press in the Journal of Geophysical Research-Atmospheres , a publication of the American Geophysical Union.
Transportation is one of the largest contributors to urban air pollution for pollutants such as carbon monoxide, nitrogen oxides, benzene, ozone, and fine particulate matter (PM 2.5 ). Our work builds on prior research by employing a much larger sample of global cities, allowing for the exploration of factors (i.e.,
The increase in anthropogenic emissions comes directly from energy supply (47%); industry (30%); transport (11%); and buildings (3%) sectors, the WG reported with medium confidence. The global economic crisis 2007/2008 only temporarily reduced emissions. benefits together with mitigation options that can be increased by technology advances.
This study builds on the 2007 Environmental Assessment of Plug-in Hybrid Electric Vehicles by EPRI and NRDC ( earlier post ), which showed that plug-in hybrid electric vehicles could contribute to reductions in national greenhouse gas emissions, while also leading to improved air quality. levels throughout the United States.
Since Mexico City children mostly attend underprovided public schools, children do not build cognitive reserves that serve as a defense to pollution impacts. In the US, 200 million people live in areas where pollutants such as ozone and fine particulate matter exceed the standards.
60% of ground-level ozone (O 3 ) precursors, 6% of fine particulate matter (PM 2.5 ), and 22% of greenhouse gases (GHGs) emitted. On-road transportation accounts for approximately 20% of United States energy consumption. Associated tailpipe emissions alone account for 40?60% —Tessum et al. Christopher W. Tessum, Julian D.
This system builds on the long-term experience of WMO in greenhouse gas instrumental measurements and atmospheric modelling. It also plays an important role in the destruction of the stratospheric ozone layer which protects us from the harmful ultraviolet rays of the sun. Its atmospheric concentration in 2016 was 328.9
