Punjab Chief Minister Amarinder Singh on Wednesday pledged to make the state's healthiest in India by providing pollution free air and water.
"As we launch #TandarustPunjab 2.0, we are on our way to make Punjab the healthiest state in India by launching with a mission to provide clean air and water, safe food, and ensuring a healthy environment," he tweeted.
"Looking forward to your support on this mission! #WorldEnvironmentDay."
The United Nations Environment Programme (UNEP) has chosen air pollution as the theme for this year's World Environment Day that falls on June 5 with China as the host country.
