The Punjab government is scaling up its Liquid Tree project, a microalgae-based system that absorbs carbon dioxide in urban areas where traditional trees cannot be planted. The initiative, run by the Punjab Environmental Protection Agency, uses over 100 types of microalgae collected from across Pakistan. The first EPA-certified liquid tree in Faisalabad will be relocated to Lahore as part of the expansion. In the first phase, liquid trees will be installed in shopping malls and public indoor and outdoor spaces. Chief Minister Maryam Nawaz called it a scientific solution to rising CO2 levels and smog. The EPA has also demolished fat-melting units, banned thin plastic bags, and mandated green buffer zones around industrial areas. The project targets air quality improvements in densely populated urban centers.
