Few international locations worldwide are literally respiration clear air, in accordance with a brand new report
Air air pollution continues to be one of many largest well being crises of our time, with scientists describing it as a “international well being catastrophe”. A 2023 report by Swiss air high quality expertise firm IQAir highlights the grim actuality: Solely 7 international locations worldwide meet the World Well being Group's (WHO) tips for protected air air pollution.
Utilizing knowledge from greater than 30,000 monitoring stations in 134 international locations, territories and areas, the International Air High quality Report reveals that 124 of those places exceeded the protected annual restrict of 5 µg/m³ PM2.5 set by the WHO. PM2.5 are particles sufficiently small to penetrate deep into the lungs and enter the bloodstream. Publicity to those particles has been linked to quite a few well being issues, together with coronary heart and lung illness, hypertension, bronchial asthma, despair, nervousness, and even untimely demise.
The champions of unpolluted air
Notably, solely Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand maintained air high quality inside protected PM2.5 limits in 2023. A number of territories, corresponding to Puerto Rico, Bermuda and French Polynesia additionally achieved protected air ranges. Amongst European international locations, Iceland was first with the cleanest air (4 µg/m³), adopted by Estonia (4.7 µg/m³) and Finland (4.9 µg/m³). Whereas many European international locations have been labeled “inexperienced” – indicating air air pollution ranges as much as twice the protected normal – these three nations stood out for sustaining exemplary air high quality.
A notice of optimism
The report exhibits a promising development in Europe. In 2023, 54% of European cities have been categorised as 'inexperienced', up from 39% in 2022. International locations corresponding to Sweden, Eire, Norway and Portugal maintained comparatively low PM2.5 ranges, reflecting efforts to fight air pollution .
International locations within the 'yellow' class – with air pollution ranges as much as thrice the protected restrict – included Lithuania, the Czech Republic and Malta. Croatia emerged as successful story, decreasing PM2.5 ranges by greater than 40% in comparison with 2022, primarily because of the shift to renewable vitality sources, which now account for over 31% of its vitality combine. Croatia additionally goals to part out coal by 2033 and scale back methane emissions by 30% by 2030.
However, international locations within the “orange” class – with pollution as much as 5 instances above the protected stage – embody Moldova, Romania, Greece and Turkey. Regardless of enchancment efforts, Bosnia and Herzegovina stays essentially the most polluted nation in Europe, adopted by North Macedonia, with PM2.5 ranges exceeding the WHO normal by 5 instances. Iğdır, Turkey was reported as essentially the most polluted metropolis in Europe.
Essentially the most polluted international locations on the planet
South and Central Asia maintain the disagreeable distinction of being residence to the world's most polluted international locations and cities. Bangladesh topped the listing with an alarming PM2.5 stage of 79.9 µg/m³, greater than 15 instances the WHO guideline. Pakistan adopted, with air pollution ranges 14 instances above the protected normal, whereas India got here third, residence to 4 of the world's most polluted cities. Tajikistan and Burkina Faso accomplished the highest 5.
North America additionally noticed notable adjustments, with Canada recording the very best air pollution ranges within the area for the primary time, residence to 13 of the continent's most polluted cities.
Air high quality as a common proper
The report highlights the significance of air high quality knowledge in driving coverage change. Nevertheless, the dearth of monitoring infrastructure in lots of areas, notably in Africa, leaves giant populations with out entry to vital air high quality info. In consequence, thousands and thousands of persons are nonetheless unaware of the hazards they face day by day.
Name to motion
Tackling air air pollution requires international cooperation and decisive motion. Greenpeace Worldwide Senior Air High quality Scientist Aidan Farrow stresses the urgency to scale back reliance on combustion-based vitality and deal with the causes of transboundary haze.
“In 2023, air air pollution stays a world well being catastrophe,” notes Farrow. “The options are there – we want the political and social will to implement them.”
Because the proof mounts, the message is evident: Clear air is a elementary human proper. Securing it requires a collective dedication to science-driven change and a shared imaginative and prescient for a more healthy planet.
