Punjab launches 'Liquid Tree' project using microalgae to capture CO2 in Lahore | carboncredit.io

Punjab Chief Minister Maryam Nawaz Sharif has launched a new 'Liquid Tree' initiative in Lahore, deploying an EPA-certified artificial tree that uses microalgae to absorb carbon dioxide and release oxygen. The system was developed after testing over 100 species of microalgae collected from across Pakistan, with the most effective strains identified from Sukkur and cultivated with Government College University Faisalabad. The unit includes an AI-based calculator that monitors real-time CO2 absorption and oxygen output. The project aims to reduce urban pollution and smog, with initial installations planned inside and outside major shopping malls and commercial centers. While the technology is novel and the local sourcing of algae is a plus, the article does not provide key numbers such as the CO2 capture rate per unit, cost per installation, or how many units will be deployed. Without those metrics, it is hard to compare this to other urban carbon capture approaches or natural tree planting. The expansion plan is vague but the pilot is worth watching for real-world performance data.
