Lahore: Punjab Chief Minister Maryam Nawaz Sharif has announced the launch of Pakistan's first Environment Protection Agency (EPA)-certified "Liquid Tree," describing the innovative technology as a major breakthrough in the province's efforts to combat pollution, reduce carbon emissions, and improve urban environmental conditions.
First EPA Certification Since 1987
The chief minister said the Liquid Tree is the first technology to receive certification from the Punjab EPA since the agency's establishment in 1987. Developed as a bio-artificial tree, the system is designed to absorb carbon dioxide from the atmosphere and release oxygen, helping improve air quality in densely populated urban areas.
Commitment to Environmental Sustainability
Reaffirming her government's commitment to transforming Punjab into an environmentally sustainable province, Maryam Nawaz said the successful development and testing of the Liquid Tree marked a significant milestone in the fight against climate change, smog, and environmental degradation.
Extensive Research and Development
According to the chief minister, the project involved extensive scientific research and testing. More than 100 species of microalgae were collected from different regions of the country, ranging from Karachi to Khyber Pakhtunkhwa. Over a seven-month period, researchers evaluated the carbon sequestration capacity and environmental performance of each species. She said the most effective algae species was identified in Sukkur, Sindh, and was subsequently cultivated with the support of Government College University (GCU) Faisalabad for use in the innovative system.
AI-Based Monitoring System
The Liquid Tree is equipped with an artificial intelligence-based monitoring system that provides real-time data on the amount of carbon dioxide being absorbed and the volume of oxygen being released, enabling continuous assessment of its environmental impact. Maryam Nawaz praised the Environment Protection Agency, researchers, bioscientists, and technical experts involved in the project, saying the successful trial reflected the scientific expertise, innovation, and dedication of Punjab's research community.
Expansion Plans
"The successful trial of the Liquid Tree will bring a significant change in our efforts to improve the environment and tackle pollution," she said, adding that the government had decided to expand the project following its successful testing phase. Under the first phase of implementation, Liquid Trees will be installed at major shopping malls in both indoor and outdoor settings. The chief minister expressed confidence that the technology would prove to be a game changer in reducing pollution levels in urban centres.
How the Liquid Tree Works
The system uses algae cultivated in water through a bioreactor mechanism that captures carbon dioxide and converts it into oxygen. According to officials, the technology represents one of the most advanced scientific approaches available for addressing carbon emissions and mitigating the effects of smog in cities. Maryam Nawaz noted that the installation of artificial trees in commercial buildings, plazas, shopping centres, and business districts would complement traditional afforestation efforts and contribute to improving environmental quality in areas where planting large numbers of natural trees may not be feasible.
Broader Environmental Agenda
She said the initiative forms part of the Punjab government's broader environmental agenda, which includes anti-smog measures, afforestation campaigns, and the adoption of innovative technologies aimed at building a cleaner, greener, and more climate-resilient Punjab.
