Over a span of two years, we artificially elevated the levels of either ozone or diesel exhaust fumes around plots of flowering black mustard plants, all within fields of non-flowering wheat. Air pollutants like ozone are highly reactive and can degrade the signals by destroying the chemicals that make up a flower’s scent.
and PM10), nitrogen dioxide (NO 2) nitrogen oxide (NO), carbon monoxide (CO) and ozone (O 3). The data we receive from Ricardo will provide us with quality data needed to make informed decisions regarding our policy and action plans and help to deliver health and economic benefits to the millions of people in our region.”
Volatile organic compounds (VOCs) combine with nitrogen oxide to create ozone, a key precursor to smog. Over the past several decades, public health and environmental concerns have made controlling smog a top national policy goal in China and enforcement an increasingly critical issue for companies to navigate. Policy & Politics.
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,
The United States-based oil major’s willingness to publicly throw down the gauntlet to policy-makers underscores the stakes for the fossil fuel industry as the EU fleshes out its plans to slash carbon emissions, ahead of June’s European parliament elections.
“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
Friday, 17 June, the hottest day of the year so far, saw unhealthy levels of Ozone across the Borough. Findings include: · Tuesday, 1 March, the day of tube strikes in London, led to high increases in rush hour NO2, as more people relied on road transport.
Health costs incurred as a result of air pollution are collectively higher in London than any other city in Europe, according to study that quantifies how much money European city dwellers spend due to particulate matter, NO2, and ozone. per cent and 0.54 per cent respectively.
When people are asked to explain climate change, many think it has something to do with the hole in the ozone layer. Marshall says, “More than four in 10 Americans think the ozone hole actually causes global warming. And so many of them remember and understand so much about ozone depletion. Why is that?
For decades, scientists have closely observed the ozone layer , which protects Earth from the sun’s harmful ultraviolet (UV) radiation. Ozone is created in our atmosphere when the sun’s high-energy UV rays rupture the stable covalent bonds of atmospheric oxygen (O2) molecules, transforming them into free radicals.
This study also included a series of workshops with the local citizens understanding different perspectives, how data could be best communicated as well as discussing possible interventions and policy changes to improve air quality for everyone.
Weld County, a 4,000-square-mile area northeast of Denver, this year received failing air quality grades for ozone and particulate matter — pollutants linked to fossil fuel extraction — from the American Lung Association. The Colorado Springs area received failing grades for ozone in 2024.
Now that the UK is no longer part of the European Union (EU), concern has been increasing that the UK may fall further behind if a strategic policy is not decided. With the UK’s future environmental policy still clouded in uncertainty, the clarity that methodologies like IRMS provide cannot be undervalued.
Once launched, the data generated from the network can be used in a myriad of ways, says AirLabs, enabling the public to map less polluted routes from A-to-B, feeding into local traffic management policy and providing NHS Trusts and schools with information to help raise awareness of air pollution and protect vulnerable communities.
Japan to launch review of coal export policy. Japan looks set to beef up a key plank of its climate policy in the face of mounting calls from allies for the country to strengthen its decarbonisation plans ahead of the COP26 Climate Summit in Glasgow this year. Plus all the top green business news from around the world.
Some use technologies like ozone oxidation, and membrane filtration. By combining existing technologies, fostering innovation, and implementing strategic policies, we can move towards a future with cleaner and safer water for all. We all have a role to play, from policymakers and researchers to businesses and individuals.
Furthermore, diseases are spreading quickly due to climate change and expanding global trade. For instance, seeds are grown and traded around the world, and there are many examples where diseases in agriculture that originated in other countries have spread across the world in a matter of weeks or months via the seed market.
In the presence of the sun’s rays, nitrogen molecules set of a chain of reactions that produce ozone and destroy free-floating atmospheric methane. Clouds form and then fade, and molecules like ozone get destroyed by chemical processes within months. (In It’s tough to pin down the meaning of all this chemistry.
The fund, which is available to six million customers, instead aims to invest in companies that deliver products and services that make a positive impact on the environment, and in firms making a difference through progressive policies, it said.
The state has set targets of 1,500 MW of storage by 2025 and 3,000 MW by 2030, and it has created a set of policies including incentives for storage developers and procurement requirements for its biggest utilities. In New York City, the biggest battery is the 4.8 A battery business case geared toward a renewables-rich future.
Step 6: Implement the plan, establish and communicate new policies and practices. They should consider processes, materials, people, policies and projects related to energy, waste, buildings, products, packaging, supply chain, transportation, food, water, community and employee well being. Do we communicate policies company-wide?
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. According to a 2021 estimate from researchers from the University of Chicago , a failure to meet international guidelines for PM 2.5
Methane is indirectly affecting agricultural productivity through climate change and ozone pollution , which is known to harm ecosystems and plants. Fortunately, fast and ambitious methane mitigation can help avoid crop losses caused by ozone pollution.
Many pesticides release volatile organic compounds (VOCs), a precursor to ground-level ozone that acts as a powerful greenhouse gas. Its key recommendations include increasing technical assistance and direct incentives for farmers to adopt agroecological practices, and setting pesticide use reduction targets within climate policy.
Much of the sustainability literature focuses on the Global North and on issues salient to policy makers in developed countries, such as climate change, biodiversity loss, and ozone depletion. The conference will appeal to scholars, social activists, business people, and policy makers.
However, not all states have NEM policies, and these policies vary by state. But ground-level ozone and other pollutants from cars, power plants, industrial boilers, refineries and chemical plants can kill. A reputable solar company can explain the NEM in your location. Solar energy means healthier air.
Also, mining is a significant air pollutant, releasing Ozone and ~4.5Gt of CO 2e each year. Your procurement department can put in green purchasing policies. Read this article by Green Business Bureau, What Is A Green Procurement Policy , for a guide to creating a sustainable supply chain.
Several other VOCs including ethane, propane, butane, pentane, and hexane react with NOx to form ground level ozone which has harmful effects on human health and on plants. Especially methane is a potent greenhouse gas, contributing to climate change. An overlooked problem. For many years did VOC emissions receive little focus.

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.”
They should consider processes, materials, people, policies and projects related to energy, waste, buildings, products, packaging, supply chain, transportation, food, water, community and employee well being. Do we communicate policies company-wide? The initiatives should be prioritized based on impact, effort, cost and feasibility.
Now, the planetary boundaries framework has generated enormous interest in science, policy, and practice. The nine planetary Boundaries are: Stratospheric ozone: filters ultraviolet rays (UVR) coming from the sun, which would otherwise place the system is at risk.
On the other hand, the analysts estimate that £1.6bn in damages and 17,000 lives could be saved annually in Bristol, London, Manchester, and Birmingham if the cities worked to meet guidelines on all major air pollutants, which also include particulate matter and ozone.
The world's largest asset manager, BlackRock, lost $90bn in the last 10 years by keeping investments in fossil fuels, while the Church of England has been the best performing investor in the UK with its leading divestment policy. This must not happen, and the Green Recovery Act ensures it won't. It's just a question of when.
But there are other GHGs that contribute significantly to human-induced global warming such as methane (CH 4 ), nitrous oxide (N 2 0), refrigerant gasses (HFCs, PFCs, and CFCs), sulfur hexafluoride (SF 6 ), water vapor (H 2 0), and ozone (O 3 ). What’s the relevance of these different GHGs to carbon footprinting? .
What public policies are needed? A variety of policies can be applied to reduce environmental justice inequities. EPA historically has identified "critical population sub-groups" in setting ozone, particulate and other ambient air quality standards. Integrating environmental justice with climate change policies.
International and domestic measures slated for potential inclusion in the agreement could include policies to stop routine venting and flaring of methane in the oil and gas sector, and requirements for firms to fix leaks in their gas pipeline and other infrastructure, according to Reuters.
Climate change represents a major public health emergency, but its destructive and expensive toll on Americans’ health has largely been absent from the climate policy debate,” stated Dr. Vijay Limaye, lead author and NRDC scientist. As climate change exacerbates, costs will continue to rise.
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”. This will require clear policy direction.” ‘One-sided’
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.
