Punjab Expands Liquid Tree Initiative to Tackle Rising Air Pollution

Punjab is stepping up its environmental protection efforts with an ambitious expansion of its innovative Liquid Tree programme, a biotechnology-based initiative designed to improve air quality in heavily populated urban centres. The project relies on specially cultivated microalgae that naturally absorb carbon dioxide from the atmosphere and help reduce the harmful effects of air pollution and smog. Officials have confirmed that the province’s first certified Liquid Tree unit, previously installed in Faisalabad, will soon be transferred to Lahore as part of the next stage of development. According to the provincial administration, researchers have gathered over 100 varieties of microalgae from different parts of Pakistan to strengthen the programme’s effectiveness. In the initial rollout, these artificial green systems will be placed in shopping centres, public gathering areas, and other indoor and outdoor locations where conventional tree plantation is difficult. Authorities believe the technology offers a practical and science-driven approach to addressing worsening air quality challenges. The expansion comes alongside broader environmental reforms, including action against polluting industrial activities, restrictions on environmentally harmful plastics, and stricter green regulations for industrial zones. The initiative reflects Punjab’s growing focus on sustainable solutions aimed at creating healthier and cleaner cities for future generations.
