Air pollution is now the world’s fourth-largest risk factor for early death. According to the most recent State of Global Air report —which summarizes the latest scientific understanding of air pollution around the world—4.5 million deaths were linked to outdoor air pollution exposures in 2019, and another 2.2 million deaths were caused by indoor air pollution. “Despite improvements in reducing global average mortality rates from air pollution, the world’s most populous countries, India and China, continue to bear the highest burdens of disease,” says Vijay Lamaye , staff scientist at the NRDC Science Center. “This report is a sobering reminder that the climate crisis threatens to worsen air pollution problems significantly if we fail to act to cut carbon pollution.”
Residents who live near the country’s busiest ports are getting a new lens on the pollution in their backyards, and new tactics to help fight it.
In the United States, the Clean Air Act has been a crucial tool for reducing air pollution since its passage in 1970, although fossil-fuel interests aided by industry-friendly lawmakers have frequently attempted to weaken its many protections. Ensuring that this bedrock environmental law remains intact and properly enforced will always be key to maintaining and improving our air quality.

Another category of toxic compounds, polycyclic aromatic hydrocarbons , are by-products of traffic exhaust and wildfire smoke. In large amounts they have been linked to eye and lung irritation, blood and liver issues, and even cancer. In one study, the children of mothers exposed to PAHs during pregnancy showed slower brain-processing speeds and more pronounced symptoms of ADHD.
Recent findings, however, reflect how climate change–fueled wildfires and extreme heat are adding to the challenges of protecting public health. The latest report—which focuses on ozone, year-round particle pollution, and short-term particle pollution—also finds that people of color are 61 percent more likely than white people to live in a county with a failing grade in at least one of those categories, and three times more likely to live in a county that fails in all three.

Considering making the switch? Here’s everything you need to know about driving electric cars and hybrids.
But the best, most effective way to control air pollution is to speed up our transition to cleaner fuels and industrial processes. By switching over to renewable energy sources , maximizing fuel efficiency in our vehicles, and replacing more and more of our gasoline-powered cars and trucks with electric versions, we’ll be limiting air pollution at its source while also curbing the global warming that heightens so many of its worst health impacts.
A new study shows that most of us humans are likely inhaling more air pollution each year.
Historically, racist zoning policies and the discriminatory lending practices known as redlining have combined to keep polluting industries and car-choked highways away from white neighborhoods and have turned communities of color—especially poor and working-class communities of color—into sacrifice zones where residents are forced to breathe dirty air and suffer the many health problems associated with it. In addition to the increased health risks that come from living in such places, members of these communities experience economic harm in the form of missed workdays, higher medical costs, and local underinvestment.
A step-by-step guide to protecting your community from dirty development projects.
Short answer: Yes. Even a seemingly slight average temperature rise is enough to cause a dramatic transformation of our planet.

Smog can irritate the eyes and throat and also damage the lungs, especially those of children, senior citizens, and people who work or exercise outdoors. It’s even worse for people who have asthma or allergies: these extra pollutants can intensify their symptoms and trigger asthma attacks. The tiniest airborne particles in soot, whether gaseous or solid, are especially dangerous because they can penetrate the lungs and bloodstream and worsen bronchitis, lead to heart attacks, and even hasten death. In 2020 a report from Harvard’s T. H. Chan School of Public Health showed COVID-19 mortality rates in areas with more soot pollution were higher than in areas with even slightly less, showing a correlation between the virus’s deadliness and long-term exposure to fine particulate matter and illuminating an environmental justice issue .

Pollen allergies are worsening because of climate change . “Lab and field studies are showing that pollen-producing plants—especially ragweed—grow larger and produce more pollen when you increase the amount of carbon dioxide that they grow in,” Knowlton says. “Climate change also extends the pollen production season, and some studies are beginning to suggest that ragweed pollen itself might be becoming a more potent allergen.” If so, more people will suffer runny noses, fevers, itchy eyes, and other symptoms.

Air Pollution Facts, Causes air pollution environmental articles and the Effects of Pollutants in the Air NRDC
And what about the economic costs of controlling air pollution? According to a report on the Clean Air Act commissioned by NRDC, the annual benefits of cleaner air are up to 32 times greater than the cost of clean-air regulations. Those benefits include up to 370,000 avoided premature deaths, 189,000 fewer hospital admissions for cardiac and respiratory illnesses, and net economic benefits of up to $3.8 trillion for the U.S. economy every year.
The effects of air pollution on the human body vary depending on the type of pollutant and the length and level of exposure—as well as other factors, including a person’s individual health risks and the cumulative impacts of multiple pollutants or stressors.
The Trump administration failed to monitor air pollution in the toxic aftermath of Hurricane Harvey. Also: Trump is taking a chainsaw to our protections, and the EPA can’t count to 20.

Trump won’t sign the G7 climate commitment, Pruitt doesn’t have time for smog limits, and Zinke cancels science.
These are the two most prevalent types of air pollution. Smog occurs when emissions from combusting fossil fuels react with sunlight. Soot is made up of tiny particles of chemicals, soil, smoke, dust, or allergens—in the form of either gas or solids—that are carried in the air. The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines, air pollution environmental articles generally anything that combusts fossil fuels such as coal, gas, or natural gas,” Walke says.
“The less gasoline we burn, the better we’re doing to reduce air pollution and harmful effects of climate change,” Walke says. “Make good choices about transportation. When you can, walk, ride a bike, or take public transportation. For driving, choose a car that gets better miles per gallon of gas, or choose an electric car.” You can also investigate your power provider options—you may be able to request that your electricity be supplied by wind or solar. Buying your food locally cuts down on the fossil fuels burned in trucking or flying food in from across the country. And most important, “Support leaders who push for clean air and water and responsible steps on climate change,” Walke says.
Air pollution refers to the release of pollutants into the air—pollutants which are detrimental to human health and the planet as a whole. According to the World Health Organization , each year air pollution is responsible for nearly seven million deaths around the globe. Nine out of ten human beings currently breathe air that exceeds the WHO’s guideline limits for pollutants, with those living in low- and middle-income countries suffering the most. In the United States, the Clean Air Act , established in 1970, authorizes the U.S. Environmental Protection Agency to safeguard public health by regulating the emissions of these harmful air pollutants.
The Natural Resources Defense Council works to safeguard the earth – its people, its plants and animals, and the natural systems on which all life depends.
The global toll of premature deaths attributed to the burning of coal, gasoline, and diesel is breathtakingly high, with new research doubling previous estimates.

Trump’s wildfire lies, Zinke’s acronym defense, and the EPA’s forced altruism involving truck pollution.
Recently, c umulative impact mapping , which uses data on environmental conditions and demographics, has been able to show how some communities are overburdened with layers of issues, like high levels of poverty, unemployment, and pollution. Tools like the Environmental Justice Screening Method and the EPA’s EJSCREEN provide evidence of what many environmental justice communities have been explaining for decades: that we need land-use and public health reforms to ensure that vulnerable areas are not overburdened and that the people who need resources most are receiving them.
Roadside plants helped officials trace the source of a public health crisis and led to new standards for clean air in Oregon.
A recent study found that the state is home to four of the country’s most polluting power plants. But elected officials won’t even show up to hear their constituents’ concerns about it.
Ten years after the disaster at a Tennessee power plant, the cleanup crew is seeking justice. At the same time, the Trump administration is weakening protections for this toxic pollution.
In rankings for each of the three pollution categories covered by the ALA report, California cities occupy the top three slots despite significant gains the Golden State has made in the past half-century. At the other end of the spectrum, Burlington, Vermont; Honolulu; and Wilmington, North Carolina, consistently rank among the country’s best cities for air quality.
Mold and allergens from trees, weeds, and grass are also carried in the air, are exacerbated by climate change, and can be hazardous to health. Though they aren’t regulated and are less directly connected to human actions, they can be considered a form of air pollution. “When homes, schools, or businesses get water damage, mold can grow and can produce allergenic airborne pollutants,” Knowlton says. “ Mold exposure can precipitate asthma attacks or an allergic response, and some molds can even produce toxins that would be dangerous for anyone to inhale.”
But plans to cut local carbon pollution might help this asthma capital shake its wheezy reputation.
The air in southwestern Indiana is bad enough without the emissions from yet another proposed polluter.
Environmental racism isn’t limited to cities and industrial areas. Outdoor laborers, including the estimated three million migrant and seasonal farmworkers in the United States, are among the most vulnerable to air pollution—and also among the least equipped, politically, to pressure employers and lawmakers to affirm their right to breathe clean air.
Every time you go outside, you may be inhaling harmful chemicals. But don’t hold your breath. Just use your head.
No one wants to live next door to an incinerator, oil refinery, port, toxic waste dump, or other polluting site. Yet millions of people around the world do, and this puts them at a much higher risk for respiratory disease, cardiovascular disease, neurological damage, cancer, and death. In the United States, people of color are 1.5 times more likely than whites to live in areas with poor air quality, according to the ALA.

So many technological innovations in the automobile industry stem directly from guidelines intended to reduce gas guzzling. If we lose these guidelines, we’ll also lose a lot of our workforce.
By trapping the earth’s heat in the atmosphere, greenhouse gases lead to warmer temperatures, which in turn lead to the hallmarks of climate change: rising sea levels, more extreme weather, heat-related deaths, and the increased transmission of infectious diseases. In 2018 carbon dioxide accounted for 81 percent of the country’s total greenhouse gas emissions, and methane made up 10 percent. “Carbon dioxide comes from combusting fossil fuels, and methane comes from natural and industrial sources, including large amounts that are released during oil and gas drilling,” Walke says. “We emit far larger amounts of carbon dioxide, but methane is significantly more potent, so it’s also very destructive.” Another class of greenhouse gases, hydrofluorocarbons , are thousands of times more powerful than carbon dioxide in their ability to trap heat. In October 2016 more than 140 countries reached an agreement to reduce the use of these chemicals—which are found in air conditioners and refrigerators—and develop greener alternatives over time. Though President Trump was unwilling to sign on to this agreement, a bipartisan group of senators overrode his objections in 2020 and set the United States on track to slash HFCs by 85 percent by 2035. According to David Doniger , senior strategic director of NRDC’s Climate and Clean Energy program, “the agreed-to HFC phasedown will avoid the equivalent of more than 80 billion tons of carbon dioxide over the next 35 years.”

Because highways and polluting facilities have historically been sited in or next to low-income neighborhoods and communities of color, the negative effects of this pollution have been disproportionately experienced by the people who live in these communities. In 2019 the Union of Concerned Scientists found that soot exposure was 34 percent higher for Asian Americans , on average, than for other Americans. For Black people, the exposure rate was 24 percent higher; for Latinos, 23 percent higher.

A number of air pollutants pose severe health risks and can sometimes be fatal even in small amounts. Almost 200 of them are regulated by law; some of the most common are mercury, lead, dioxins, and benzene. “These are also most often emitted during gas or coal combustion, incinerating, environmental pollution articles
