On World Environment Day 2026, Union Environment Minister Bhupender Yadav and Delhi Chief Minister Rekha Gupta launched 18 "Namo Oxygen Parks" to tackle Delhi's declining air quality caused by rapid urbanization. This collaborative effort between the Centre and State establishes new urban forests as vital "green lungs" for the city. By enhancing green cover, these parks help filter air, mitigate urban heat, and promote community-led environmental stewardship, ultimately fostering better public health.
