Lahore, Karachi among world’s top polluted cities as Pakistan grapples with toxic smog 

  • IQAir records Lahore’s Air Quality Index at 598, categorizes it as “hazardous” for residents
  • Lahore faces worsening smog in winters from crop burning, vehicle emissions, industrial pollution 

ISLAMABAD: Lahore once again topped the list of world's most polluted cities while Karachi ranked at number six, Swiss monitoring group IQAir reported on Thursday as Pakistan grapples with toxic smog choking its two largest cities. 

According to IQAir, Lahore reported an Air Quality Index (AQI) of 598, which was categorized as "hazardous" while Karachi recorded a reading of 162 categorized as "unhealthy." The capitals of India and Beijing followed Lahore by coming in at number two and three in the list of most polluted cities, respectively, recording IQAir indexes of 475 and 175. 

Lahore recorded a PM2.5 of 374.4 µg/m³. The PM2.5 refers to floating particulate matter in the air measuring 2.5 micrometers in diameter or less that can be absorbed into the bloodstream upon inhalation. 

"PM2.5 concentration is currently 74.9 times the World Health Organization annual PM2.5 guideline value," IQAir said regarding Lahore, Punjab's provincial capital. 

IQAir warned Lahore residents against taking part in outdoor exercises, advising them to keep their windows closed, wear masks outdoors and operate air purifiers. 

Lahore faces worsening smog each winter from crop burning, vehicle emissions and industrial pollution that threaten public health and daily life. Smog can cause sore throats, eye irritation and respiratory illnesses, while long-term exposure increases the risk of stroke, heart disease and lung cancer. 

Smog season begins in late October, peaks from November to January and lasts through February.

Earlier in October, the government in Pakistan's most populous Punjab province conducted its first anti-smog gun operation, which helped lower the city’s unhealthy air quality levels. Anti-smog trucks sprayed fine water mist across the city to help settle dust and pollutants.

Pakistan’s main urban centers routinely rank among the most polluted cities in the world, with vehicular emissions remaining one of the top contributors to air pollution.

This severe air pollution also undermines economic productivity and diminishes the quality of life for millions of residents.

Pakistan, global crypto exchange discuss modernizing digital payments, creating job prospects 

  • Pakistani officials, Binance team discuss coordination between Islamabad, local banks and global exchanges
  • Pakistan has attempted to tap into growing crypto market to curb illicit transactions, improve oversight

ISLAMABAD: Pakistan’s finance officials and the team of a global cryptocurrency exchange on Friday held discussions aimed at modernizing the country’s digital payments system and building local talent pipelines to meet rising demand for blockchain and Web3 skills, the finance ministry said.

The development took place during a high-level meeting between Finance Minister Muhammad Aurangzeb, Pakistan Virtual Assets Regulatory Authority (PVARA) Chairman Bilal bin Saqib, domestic bank presidents and a Binance team led by Global CEO Richard Teng. The meeting was held to advance work on Pakistan’s National Digital Asset Framework, a regulatory setup to govern Pakistan’s digital assets.

Pakistan has been moving to regulate its fast-growing crypto and digital assets market by bringing virtual asset service providers (VASPs) under a formal licensing regime. Officials say the push is aimed at curbing illicit transactions, improving oversight, and encouraging innovation in blockchain-based financial services.

“Participants reviewed opportunities to modernize Pakistan’s digital payments landscape, noting that blockchain-based systems could significantly reduce costs from the country’s $38 billion annual remittance flows,” the finance ministry said in a statement. 

“Discussions also emphasized building local talent pipelines to meet rising global demand for blockchain and Web3 skills, creating high-value employment prospects for Pakistani youth.”

Blockchain is a type of digital database that is shared, transparent and tamper-resistant. Instead of being stored on one computer, the data is kept on a distributed network of computers, making it very hard to alter or hack.

Web3 refers to the next generation of the Internet built using blockchain, focusing on giving users more control over their data, identity and digital assets rather than big tech companies controlling it.

Participants of the meeting also discussed sovereign debt tokenization, which is the process of converting a country’s debt such as government bonds, into digital tokens on a blockchain, the ministry said. 

Aurangzeb called for close coordination between the government, domestic banks and global exchanges to modernize Pakistan’s payment landscape.

Participants of the meeting also discussed considering a “time-bound amnesty” to encourage users to move assets onto regulated platforms, stressing the need for stronger verifications and a risk-mitigation system.

Pakistan has attempted in recent months to tap into the country’s growing crypto market, crack down on money laundering and terror financing, and promote responsible innovation — a move analysts say could bring an estimated $25 billion in virtual assets into the tax net.

In September, Islamabad invited international crypto exchanges and other VASPs to apply for licenses to operate in the country, a step aimed at formalizing and regulating its fast-growing digital market.
