Pakistan’s Lahore, Karachi among three most polluted cities globally

  • Annual global survey by IQAir had put Lahore as the city with the worst air in the world in 2022
  • Last week heavy pollution-fueled smog forced authorities to close schools, markets in Punjab

ISLAMABAD: The eastern Pakistani city of Lahore was ranked the second most polluted city in the world on Thursday morning, according to an IQAir listing, which showed it had an Air Quality Index (AQI) of 470, which is considered ‘hazardous.’

An annual global survey by the Swiss maker of air purifiers had put Lahore as the city with the worst air in the world in 2022.

Last week heavy pollution-fueled smog forced authorities to close schools and markets in Pakistan’s most populous province of Punjab, of which Lahore is the capital.

By Thursday afternoon, Lahore’s AQI had slipped to 252, which is considered “unhealthy.”

Heavy smog has blanketed Lahore since last week, reducing visibility and leading residents to complain of a threat to their health.

“PM2.5 concentration in Lahore is currently 40.4 times the WHO annual air quality guideline value,” said IQAir, which measures air quality levels based on the concentration of lung-damaging airborne particles known as PM2.5.

The WHO recommends a maximum PM2.5 concentration of 5 micrograms per cubic meter.

Schools, offices, restaurants and businesses, aside from priority services like pharmacies, hospitals and courts, remained closed last week in Punjab to limit residents’ movement outside, according to a directive from the provincial government.

While Delhi topped the list of most polluted cities on Thursday, Pakistan’s Karachi was also ranked at number 3, with an AQI of 179, which is considered “unhealthy.” PM2.5 concentration in Karachi is currently 21.9 times the WHO annual air quality guideline value

Growing industrialization in South Asia in recent decades has fueled growing pollutants emanating from factories, construction activity and vehicles in densely populated areas.

The problem becomes more severe in cooler autumn and winter months, as temperature inversion prevents a layer of warm air from rising and traps pollutants closer to the ground.

Pakistan says multilateralism in peril, urges global powers to prioritize diplomacy over confrontation

  • The country tells the UN international security system is eroding, asks rival blocs to return to dialogue
  • It emphasizes lowering of international tensions, rebuilding of channels of communication among states

ISLAMABAD: Pakistan warned the world community on Monday that multilateralism was “in peril” amid rising global tensions, urging major powers to revive diplomacy and dialogue to prevent a further breakdown in international security.

Speaking at a UN Security Council briefing, Pakistan’s ambassador to the UN, Asim Iftikhar Ahmad, said the world was drifting toward confrontation at a time when cooperative mechanisms were weakening.

His comments came during a session addressed by Finland’s foreign minister Elina Valtonen, chairing the Organization for Security and Co-operation in Europe (OSCE), the world’s largest regional security body.

Formed out of the 1975 Helsinki Final Act, the OSCE was designed during the Cold War to reduce tensions, uphold principles of sovereignty and human rights and promote mechanisms for peaceful dispute resolution.

“Today, the foundational ethos of international relations, multilateralism, cooperation and indivisible security, as envisaged in the preamble of Helsinki Final Act, is perhaps facing its biggest challenge in decades,” Ahmed said. “The OSCE, too, is navigating a difficult geopolitical landscape, with conflict raging in the heart of Europe for nearly four years, depletion of trust and unprecedented strains on peaceful co-existence.”

He said a return to the “Helsinki spirit” of dialogue, confidence-building and cooperative security was urgently needed, not only in Europe but globally.

“This is not a matter of choice but a strategic imperative to lower tensions, rebuild essential channels of communication, and demonstrate that comprehensive security is best preserved through cooperative instruments, and not by the pursuit of hegemony and domination through military means,” he said. “Objective, inclusive, impartial, and principle-based approaches are indispensable for success.”

Ahmed’s statement came in a year when Pakistan itself fought a brief but intense war after India launched missile strikes at its city in May following a militant attack in Indian-administered Kashmir. New Delhi blamed Pakistan for the assault, an allegation Islamabad denied while calling for a transparent international investigation.

The Pakistani diplomat said the international system was increasingly defined by bloc politics, mistrust and militarization, warning that such trends undermine both regional stability and the authority of multilateral institutions, including the UN itself.

He urged member states to invest more in preventive diplomacy and the peaceful settlement of disputes as reaffirmed by the Council in Resolution 2788.

Ahmad said Pakistan hoped the OSCE would continue reinforcing models of cooperative security and that the Security Council would back partnerships that strengthen international law and the credibility of multilateral frameworks.

The path forward, he added, required “choosing cooperation over confrontation, dialogue over division, and inclusive security over bloc-based divides.”
