The PM said this while chairing a meeting in Islamabad on pollution-related issues in the country.

"In line with our manifesto, clean and pollution-free Pakistan is our top priority, and long term measures should be taken to deal with issues related to climate change," the PMO quoted the PM as saying.

PM Imran stressed that the government remains focused on maximising the green cover of our cities through massive plantation drives.

He has also directed the departments concerned to immediately devise a strategy in coordination with the provincial governments to take all necessary steps to save major cities from pollution.

The directives by the PM come as a thick smog engulfs Lahore, with the city alternating with New Delhi to take the first or second spot as the world’s most polluted city. On Tuesday, Lahore ranked 2nd on the list, having an air quality index of 181.

On Monday, the Punjab government ordered the closure of all private offices and educational institutions in the city – including Saturdays and Sundays – till January 15.

Earlier, the Lahore High Court (LHC) had directed the Punjab government to issue a notification to private offices in Lahore to halve staff attendance. The LHC had also sought a traffic plan, ordering authorities to set up an emergency helpline for the citizens facing traffic issues.

Meanwhile, the Punjab government has also constituted five anti-smog squads comprising representatives from the environment department, police, city administration, LESCO, WASA, and MCL to conduct a weekly inspection of all industries in Lahore and to take stern action on violations.
