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.
Diverse compounds are emitted by everything from motor vehicles to power plants, and include both greenhouse gases and short-lived climate pollutants – which are known to fuel global warming – as well as a host of volatile organic compounds that can lead to short- and long-term health problems in humans.
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.
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. Where were the gases coming from?
“It is critical to know when, where and how much methane is emitted from each of its sources in order to prioritize emission reductions,” said Denise Mauzerall , a co-author and core faculty member of the Center for Policy Research on Energy and the Environment at Princeton University. “We
This post is the fourth in a series titled “Real Talk on Reliability,” which will examine the reliability needs of our grid as we move toward 100 percent clean electricity and electrify more end-uses on the path to a climate stable future. It was written by Savannah M. Communities across the U.S. The Clean Air Act (CAA) requires the U.S.
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,
It sets higher standards for almost every pollutant the organization monitors. 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.
You need to remove policy hurdles such as in the Renewable Energy Directive, so that you can faster scale the hydrogen economy in Europe, and use that to build out the infrastructure”, Simon Herbert, ExxonMobil’s vice-president of low carbon solutions, told the World Hydrogen 2024 conference in Rotterdam last week.
According to a 2021 estimate from researchers from the University of Chicago , a failure to meet international guidelines for PM 2.5 Other problematic sources of air pollution include methane, which produces hazardous ground-level ozone that is linked to health conditions such as lung damage, chest pain , and exacerbated respiratory diseases.
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.”

In the 1980s, NASA’s satellite data and computer modeling helped scientists track ozone depletion and global warming. Joe Raedle / Getty Images.
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. Latham & Watkins will continue to monitor and report on Proposed Rule 2305 and its potential impacts on the logistics industry.

As of 2021, most U.S. From water usage to pollution , growing cannabis may have a larger footprint than you’d think. Energy consumption How does energy use factor into growing cannabis? Growing cannabis indoors requires a significant amount of energy.
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 such, in 2022 81% of S&P 500 companies reported their own emissions (scope 1), and the emissions of the electricity they bought (scope 2). 30 years later came COP 26 (2021) – held in Glasgow. Hence, businesses withhold the power to dent global GHG emissions and mitigate the effects of climate change.
Adding sulfate aerosols to the stratosphere would degrade the ozone layer (thereby increasing global cancer rates) and increase acid rain. It is part of a broader university effort to become a global leader in the climate and energy space. This has created a vacuum that University of Chicago leaders seem excited to fill.
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. President Biden signs Kigali Amendment, promises 'phase down' of HFCs.
or SABIC, a chemical manufacturing giant tied to one of the world’s richest royal families, and Exxon Mobil, America’s biggest energy company. Indeed, the International Energy Agency predicts that by 2030 petrochemicals will account for more than a third of the growth in world oil demand, and for almost 50% of demand by 2050.
A Public Health Watch analysis of TCEQ pollution data shows that between 2019 and 2021, annual readings soared as high as 2.1 The EPA’s National Air Toxics Assessment tool is based on weaker monitoring data from a few years back. ppb, exceeding even today’s weakened TCEQ guidelines by 50%. That’s likely an undercount,” Hopkins said.
In June, Public Health Watch, the Investigative Reporting Workshop and Grist published a year-long investigation about pollution, power, and politics in the Texas petrochemical industry. And those in power, especially at the state level, need to know.”. But the data from the monitors confirmed her worst fears.
