On 16 September, the world marked the International Day for the Preservation of the Ozone Layer. The European Space Agency (ESA) takes a closer look at this year’s ozone hole. The ozone layer in the atmosphere protects Earth from potentially harmful ultraviolet radiation. Ozone depletion is greatest at the South Pole.
New Delhi, November 2021: A municipal truck uses anti-smog gun to spray water on the road for dust suppression (image credit: PradeepGaurs / Shutterstock.com). We’ve done it already in the 1990s, when international cooperation quickly phased out ozone-depleting chemicals and stopped the dangerous ozone hole from getting ever-bigger.
The gas, CFC-11, was banned in 2010 under the Montreal Protocol — the international treaty to eliminate substances that wreck the Earth’s protective ozone layer. Years of efforts to protect the ozone layer might be reversed if the emissions continued, experts warned.
The website offers countywide information and updates about particulate matter, nitrogen dioxide and ozone. In March 2021, Oxford City Council was awarded £162,500 to develop an air quality community website to help raise awareness of air pollution across Oxfordshire. and PM10) ozone, and nitrogen dioxide.
EEA estimates from 2019 attributed approximately 307,000 premature deaths to fine particulate matter in the 27 EU Member States, with a further 40,400 linked to nitrogen dioxide, and 16,800 to ground-level ozone. and PM10), ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. Air Pollution: A Case for Action Beyond 2021.
Tue, 03/23/2021 - 01:15. Volatile organic compounds (VOCs) combine with nitrogen oxide to create ozone, a key precursor to smog. When energy use surges in the autumn and winter seasons, particulate matter and ozone increase to dangerously high levels. China’s new frontier for VOC regulations. Shuying Xu.
We also measure gases that are responsible for the formation of ground-level ozone, which is very harmful to human health,” said Schreier. The five-year project will run until 2021. In a next step, the Vienna MAX-DOAS measurements are however designed to look into other pollutants, including particulate matter. “We What is MAX-DOAS?
Due to its climate and indirect health impacts (methane is a precursor for ozone which is an air pollutant that damages human health and crops), methane mitigation has recently become a global policy priority.
The guidelines also create new standards for peak season ozone — which occurs during the summer months when afternoon light mixes with ground-level volatile compounds — and carbon monoxide, caused by vehicles and machinery. and PM10 — but loosening the standard for sulfur dioxide.
The new ‘OxAria’ study started on 1st July, extending an existing collaboration which has enabled five low-cost air pollution sensors to be installed at city centre locations, generating real-time information on key air pollutants, including nitrogen oxides (NO, NO2), carbon monoxide (CO), ozone (O3) and particulate matter (PM1, PM2.5,
CFCs were destroying the ozone layer high in the Earth’s atmosphere, which is essential for protecting life from the Sun’s harmful ultraviolet radiation. But when they break down, they create chlorine that reacts with the protective ozone, letting dangerous radiation through to the Earth’s surface. How HFCs keep rooms and food cool.
Of all those options, the charcoal grill produces the most CO2 and contributes more to ground-level ozone. To find a public fireworks displays in your state, check out the Parade list for 2021. However, if using a charcoal grill, there are options for a lighter footprint. Red, White & Blue fun.
According to a 2021 estimate from researchers from the University of Chicago , a failure to meet international guidelines for PM 2.5 These particles, which are produced from wildfires and the burning of fossil fuels, can lodge themselves deep into people’s lungs and cause respiratory, cardiovascular, and neurological damage.
For example, Shell’s Quest project in Canada, capable of producing 900 tonnes of hydrogen a day, captured five million tonnes of CO2 from 2015-2021 — but released more than 7.5 .” Oil Companies Spy Opportunities The track record of the fewer than 10 existing commercial blue hydrogen plants in operation has been uneven.
At a contentious board hearing on May 7, 2021, the South Coast Air Quality Management District (SCAQMD) approved a first-in-the-nation rule to regulate trucking emissions from warehouses by a 9-4 vote. These state and federal standards require areas to reach certain ambient concentrations of ozone to be considered in “attainment.”
The atmospheric chemist had won a Nobel Prize in 1995 for demonstrating how humanity was destroying the ozone layer, just one of the many ways people had radically altered the planet, from urbanization to releasing greenhouse gases. My remark had a major impact on the audience,” Crutzen, who died in 2021, recalled years later.
Global Witness concluded using public data that despite capturing five million tonnes of CO2 from 2015 to 2021, Quest released a further 7.5 It could also contribute to increases in ground-level ozone pollution — which is harmful to human health. million tonnes of greenhouse gases during the same period.
The Basin does not meet the state or federal ambient air quality standards for ozone and particulate matter, and existing regulations have to date proved insufficient to bring the Basin into compliance. The SCAQMD is the local agency responsible for attaining these clean air standards in the Basin. Facility-Based Mobile Source Measures.

Volatile Organic Compounds (VOCs) can be found in some products, which damage the ozone layer when released into the environment. With this tip in mind, EcoWatch listed their seven best ecological cleaning products in their 2021 article 7 Best Eco-Friendly Cleaning Products of 2022. Look for certified bio-based cleaning products.
It’s very, very, very bad,” she says in ABC’s prime-time Earth Day special , letting out heavy sighs and listing jumbled statistics about deforestation and the hole in the ozone layer. “It’s crazy what we’re doing. The bartender, Kevin Costner, says he used to be scared, too — until he started doing something about it. I recycle these.”
Several companies, including Gradient where Romanin is CEO (which landed him on the 2021 Grist 50 list ), are developing new AC technologies and approaches that are starting to show what a more efficient, less climate-intensive approach to cooling will look like. Romanin is one of those working on the problem.

When hydrogen is combusted for heating, a 2021 paper found that it can create nitrogen oxides (NOx), an air pollutant that is “harmful in its own right and is a precursor to other pollutants of concern such as fine particulate matter and ozone”.
The Act follows the model of the most successful environmental treaty - the Montreal Protocol, which banned CFCs and HFCs, and is healing the hole in our ozone layer. This must not happen, and the Green Recovery Act ensures it won't. One way or another, the principles of Green Recovery Act will be put into law. It's just a question of when.
has grown from around $250 million in 2012 to over $1 billion in 2021. When exposed to sunlight, volatile organic compounds and nitrogen oxides transform into ozone, which is especially dangerous to children and the elderly. The value of exported pellets in the U.S.
Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) for six common air pollutants: particulate matter (PM), ozone, lead, carbon monoxide, sulfur dioxide, and nitrogen dioxide. The Clean Air Act (CAA) requires the U.S. Researchers have found that across the U.S.,
Mon, 05/24/2021 - 01:30. EPA historically has identified "critical population sub-groups" in setting ozone, particulate and other ambient air quality standards. The arc of the moral universe is bending toward environmental justice. In his historic March 1968 speech at Washington’s National Cathedral, the Rev. Martin Luther King, Jr.
China’s new frontier for VOC regulations Shuying Xu Tue, 03/23/2021 – 01:15 As the global economy reawakens after the COVID-19 shutdown, air emissions and VOC enforcement in China remain a hot topic. Volatile organic compounds (VOCs) combine with nitrogen oxide to create ozone, a key precursor to smog.

As of 2021, most U.S. In Vizuete’s own words, “if plants produce VOCs, there is a high possibility that under certain conditions, cannabis cultivation could impact the ozone.” Today is April 20, often known as the unofficial holiday when many people celebrate and enjoy their favorite leafy green, marijuana.
Pollutants from vehicle combustion, including nitrogen oxides and volatile organic compounds, react in sunlight to form ozone. rates of preterm birth increased 4 percent between 2020 and 2021 — and rates were far higher in Black women (14.8 And the U.S. Bates / Grist A 2023 study found that the average preterm birth rate was 7.9
Adding sulfate aerosols to the stratosphere would degrade the ozone layer (thereby increasing global cancer rates) and increase acid rain. In November 2021, Alivisatos charged a university committee with the task of determining how the university could best establish itself as a “global leader in the climate and energy space.”
The package also included new interim targets requiring manufacturers to cut emissions from new cars by 55 per cent and from new vans by 50 per cent by 2030 compared to 2021 levels, as well as plans for new metrics for measuring the lifecycle emissions of vehicles.
30 years later came COP 26 (2021) – held in Glasgow. Carbon accounting provides long-term business viability A 2021 survey reporting 83% of consumers declared that it’s very important for them to buy from a company that operates sustainably. COP26 brought together 120 world leaders and over 40,000 registered participants.

Soon after the 2024 legislative session kicked off in January, lawmakers introduced a suite of proposals intended to rein in ozone pollution from oil and gas activity, the very sort of bills the industry’s ballot measures seemed designed to block. Ozone pollution is linked to shortness of breath, asthma attacks, and heart damage.
This spring, a Dutch court is due to hear Shell’s appeal of a 2021 order to slash the company’s carbon dioxide (CO2) emissions 45 percent by 2030, issued in response to a suit filed by environmental group Milieudefensie. As a minimum statement, therefore, human activities must have contributed to the increase in carbon dioxide and methane.”
In May 2021, the TCEQ issued a permit to GCGV. By early June, the monitors registered a three-hour spike in ozone levels, which, if sustained over time, Nye said, would exceed federal guidelines. Ozone is an ingredient in smog and a respiratory irritant. The ability to monitor in real time is critical, Hilliard said.
A Public Health Watch analysis of TCEQ pollution data shows that between 2019 and 2021, annual readings soared as high as 2.1 In 2014, he criticized the EPA’s efforts to regulate ozone, an odorless, colorless ingredient in smog that exacerbates asthma. “I 11, 2021, the canister registered an annual average benzene level of 2.1
These include climate change, biosphere integrity (functional and generic), land-system change, freshwater use, biogeochemical flows (nitrogen and phosphorus), ocean acidification, atmospheric aerosol pollution, stratospheric ozone depletion, and the release of novel chemicals. We the Power is a 2021 documentary on climate change.
Ozone, which can aggravate lung diseases including asthma and emphysema, was well above the EPA’s eight-hour limit. Between 2016 and 2021, the Texas legislature slashed the TCEQ’s funding by 20 percent, even as it increased the state budget by 16 percent. They gather real-time readings for ozone, nitrogen oxides and particulate matter.
Left: Trend from 2017-2021. Right: Trend from 1983-2021. One of the great things about reducing methane emissions is that you always get large public health and ecosystem benefits as methane is a precursor to surface ozone formation, and that’s toxic to both people and plants,” Shindell said.
