Punjab government has decided to expand 'Liquid Tree' project as part of its efforts to promote an eco-friendly province through modern scientific solutions.

In a statement, Punjab Chief Minister Maryam Nawaz Sharif said Pakistan's first EPA-certified liquid tree will be shifted from Faisalabad to Lahore under the expansion plan.

She said more than one hundred species of microalgae have been collected from regions spanning Karachi to Khyber for the project.

In the initial phase, liquid trees will be installed in major shopping malls, as well as in indoor and outdoor public spaces, to help reduce urban air pollution.
