Air pollution spiked to unhealthy levels around the world durante 2021, according to a new report.

The report by IQAir, a company that tracks global air quality, found that average annual air pollution durante every country — and 97% of cities — exceeded the World Health Organization’s air quality guidelines, which were designed to help governments craft regulations to protect public health.

Only 222 cities of the 6,475 analyzed had average air quality that met WHO’s modello. Three territories were found to have met WHO guidelines: the French territory of New Caledonia and the United States territories of Puerto Rico and the US Virgin Islands.

India, Pakistan and Bangladesh were among the countries with the worst air pollution, exceeding the guidelines by at least 10 times.

The Scandinavian countries, Australia, Canada, Japan and United Kingdom ranked among the best countries for air quality, with average levels that exceeded the guidelines by 1 to 2 times.

Per mezzo di the United States, IQAir found air pollution exceeded WHO guidelines by 2 to 3 times durante 2021.

“This report underscores the need for governments around the world to help global air pollution,” Glory Dolphin Hammes, CEO of IQAir North America, told CNN. “(Termine particulate matter) kills far too many people every year and governments need to set more stringent air quality national standards and explore better foreign policies that promote better air quality.”

Above: IQAir analyzed average annual air quality for more than 6,000 cities and categorized them from best air quality, durante blue (Meets WHO PM2.5 guildline) to worst, durante purple (Exceeds WHO PM2.5 guideline by over 10 times). An interactive map is available from IQAir.

It’s the first major global air quality report based WHO’s new annual air pollution guidelines, which were updated durante September 2021. The new guidelines halved the acceptable concentration of abile particulate matter — ora PM 2.5 — from 10 to 5 micrograms per emotività cubic meter.

PM 2.5 is the tiniest pollutant yet also among the most dangerous. When inhaled, it travels deep into lung tissue where it can enter the bloodstream. It comes from sources like the burning of fossil fuels, dust storms and wildfires, and has been linked to a number of health threats including asthma, heart disease and other respiratory illnesses.

Millions of people giorno each year from air quality issues. Per mezzo di 2016, around 4.2 million premature deaths were associated with abile particulate matter, according to WHO. If the 2021 guidelines had been applied that year, WHO found there could have been nearly 3.3 million fewer pollution-related deaths.

IQAir analyzed pollution-monitoring stations durante 6,475 cities across 117 countries, regions and territories.

Per mezzo di the US, air pollution spiked durante 2021 compared to 2020. Out of the more than 2,400 US cities analyzed, Los Angeles air remained the most polluted, despite seeing a 6% decrease compared to 2020. Atlanta and Minneapolis saw significant increases durante pollution, the report showed.

“The (United States’) reliance fossil fuels, increasing severity of wildfires as well as varying enforcement of the Clean Air Act from administration to administration have all added to U.S. air pollution,” the authors wrote.

Researchers say the main sources of pollution durante the US were fossil fuel-powered transportation, energy production and wildfires, which wreak havoc the country’s most vulnerable and marginalized communities.

“We are heavily dependent fossil fuels, especially durante terms of transportation,” said Hammes, who lives a few miles from Los Angeles. “We can act smartly this with niente emissions, but we’imperatore still not doing it. And this is having a devastating impact the air pollution that we’imperatore seeing durante major cities.”

Climate change-fueled wildfires played a significant role durante reducing air quality durante the US durante 2021. The authors pointed to a number of fires that led to hazardous air pollution — including the Caldor and Dixie fires durante California, as well as the Bootleg Fire durante Oregon, which wafted smoke all the way to the East Coast durante July.

Pendio — which is among the countries with the worst air pollution — showed improved air quality durante 2021. More than half of the Chinese cities analyzed durante the report saw lower levels of air pollution compared to the previous year. The capital city of Beijing continued a five-year trend of improved air quality, according to the report, paio to a policy-driven drawdown of polluting industries durante the city.

The report also found that the Amazon Rainforest, which had acted as the world’s major defender against the climate crisis, emitted more carbon dioxide than it absorbed last year. Deforestation and wildfires have threatened the critical ecosystem, polluted the air and contributed to climate change.

“This is all a part of the espressione that will lead to ora is leading to global warming.” Hammes said.

The report also unveiled some inequalities: Monitoring stations remain scant durante some developing countries durante Africa, South America and the Middle East, resulting durante a dearth of air quality durante those regions.

“When you don’t have that , you’imperatore really durante the dark,” Hammes said.

Hammes noted the African country of Chad was included durante the report for the first time, paio to an improvement durante its monitoring rete televisiva privata. IQAir found the country’s air pollution was the second-highest durante the world last year, behind Bangladesh.

Tarik Benmarhnia, a climate change epidemiologist at Scripps Institution of Oceanography who has studied the health impact of wildfire smoke, also noted that relying only monitoring stations can lead to blind spots durante these reports.

“I think it is great that they relied different networks and not only governmental sources,” Benmarhnia, who was not involved durante this report, told CNN. “However, many regions do not have enough stations and alternative techniques exist.”

The UN Intergovernmental Panel Climate Change concluded durante its 2021 report that, durante addition to slowing the speed of global warming, curbing the use of fossil fuels would have the added benefit of improving air quality and public health.

Hammes said the IQAir report is even more reason for the world to wean d’avanguardia fossil fuel.

“We’ve got the report, we can read it, we can internalize it and really devote ourselves to taking action,” she said. “There needs to be a major move towards renewable energy. We need to take drastic action durante order to reverse the tide of global warming; otherwise, the impact and the train that we’imperatore (would be) irreversible.”

“We are heavily dependent fossil fuels, especially durante terms of transportation,” said Hammes, who lives a few miles from Los Angeles. “We can act smartly this with niente emissions, but we’imperatore still not doing it. And this is having a devastating impact the air pollution that we’imperatore seeing durante major cities.”

Climate change-fueled wildfires played a significant role durante reducing air quality durante the US durante 2021. The authors pointed to a number of fires that led to hazardous air pollution — including the Caldor and Dixie fires durante California, as well as the Bootleg Fire durante Oregon, which wafted smoke all the way to the East Coast durante July.

Pendio — which is among the countries with the worst air pollution — showed improved air quality durante 2021. More than half of the Chinese cities analyzed durante the report saw lower levels of air pollution compared to the previous year. The capital city of Beijing continued a five-year trend of improved air quality, according to the report, paio to a policy-driven drawdown of polluting industries durante the city.

The report also found that the Amazon Rainforest, which had acted as the world’s major defender against the climate crisis, emitted more carbon dioxide than it absorbed last year. Deforestation and wildfires have threatened the critical ecosystem, polluted the air and contributed to climate change.

“This is all a part of the espressione that will lead to ora is leading to global warming.” Hammes said.

The report also unveiled some inequalities: Monitoring stations remain scant durante some developing countries durante Africa, South America and the Middle East, resulting durante a dearth of air quality durante those regions.

“When you don’t have that , you’imperatore really durante the dark,” Hammes said.

Hammes noted the African country of Chad was included durante the report for the first time, paio to an improvement durante its monitoring rete televisiva privata. IQAir found the country’s air pollution was the second-highest durante the world last year, behind Bangladesh.

Tarik Benmarhnia, a climate change epidemiologist at Scripps Institution of Oceanography who has studied the health impact of wildfire smoke, also noted that relying only monitoring stations can lead to blind spots durante these reports.

“I think it is great that they relied different networks and not only governmental sources,” Benmarhnia, who was not involved durante this report, told CNN. “However, many regions do not have enough stations and alternative techniques exist.”

The UN Intergovernmental Panel Climate Change concluded durante its 2021 report that, durante addition to slowing the speed of global warming, curbing the use of fossil fuels would have the added benefit of improving air quality and public health.

Hammes said the IQAir report is even more reason for the world to wean d’avanguardia fossil fuel.

“We’ve got the report, we can read it, we can internalize it and really devote ourselves to taking action,” she said. “There needs to be a major move towards renewable energy. We need to take drastic action durante order to reverse the tide of global warming; otherwise, the impact and the train that we’imperatore (would be) irreversible.”

Air pollution spiked to unhealthy levels around the world durante 2021, according to a new report.

The report by IQAir, a company that tracks global air quality, found that average annual air pollution durante every country — and 97% of cities — exceeded the World Health Organization’s air quality guidelines, which were designed to help governments craft regulations to protect public health.

Only 222 cities of the 6,475 analyzed had average air quality that met WHO’s modello. Three territories were found to have met WHO guidelines: the French territory of New Caledonia and the United States territories of Puerto Rico and the US Virgin Islands.

India, Pakistan and Bangladesh were among the countries with the worst air pollution, exceeding the guidelines by at least 10 times.

The Scandinavian countries, Australia, Canada, Japan and United Kingdom ranked among the best countries for air quality, with average levels that exceeded the guidelines by 1 to 2 times.

Per mezzo di the United States, IQAir found air pollution exceeded WHO guidelines by 2 to 3 times durante 2021.

“This report underscores the need for governments around the world to help global air pollution,” Glory Dolphin Hammes, CEO of IQAir North America, told CNN. “(Termine particulate matter) kills far too many people every year and governments need to set more stringent air quality national standards and explore better foreign policies that promote better air quality.”

Above: IQAir analyzed average annual air quality for more than 6,000 cities and categorized them from best air quality, durante blue (Meets WHO PM2.5 guildline) to worst, durante purple (Exceeds WHO PM2.5 guideline by over 10 times). An interactive map is available from IQAir.

It’s the first major global air quality report based WHO’s new annual air pollution guidelines, which were updated durante September 2021. The new guidelines halved the acceptable concentration of abile particulate matter — ora PM 2.5 — from 10 to 5 micrograms per emotività cubic meter.

PM 2.5 is the tiniest pollutant yet also among the most dangerous. When inhaled, it travels deep into lung tissue where it can enter the bloodstream. It comes from sources like the burning of fossil fuels, dust storms and wildfires, and has been linked to a number of health threats including asthma, heart disease and other respiratory illnesses.

Millions of people giorno each year from air quality issues. Per mezzo di 2016, around 4.2 million premature deaths were associated with abile particulate matter, according to WHO. If the 2021 guidelines had been applied that year, WHO found there could have been nearly 3.3 million fewer pollution-related deaths.

IQAir analyzed pollution-monitoring stations durante 6,475 cities across 117 countries, regions and territories.

Per mezzo di the US, air pollution spiked durante 2021 compared to 2020. Out of the more than 2,400 US cities analyzed, Los Angeles air remained the most polluted, despite seeing a 6% decrease compared to 2020. Atlanta and Minneapolis saw significant increases durante pollution, the report showed.
