Meanwhile, on Sunday, the Leader of the Opposition in the Lok Sabha, Rahul Gandhi, called for a parliamentary debate on air pollution and asked the government to ensure "enough money" in the Union Budget to tackle the issue.
In a Facebook post, Gandhi read messages from citizens, and in a self-made video, he urged Prime Minister Narendra Modi to declare air pollution a national health emergency.
In the self-made video, Lok Sabha LoP said, "It is about time the government allows a discussion in Parliament and the Prime Minister should declare pollution a national health emergency... We need to come together and develop a serious plan... We need to make sure there is enough money in the budget to tackle this problem."
Sharing the post, the Congress leader wrote, "Over the last few days, I've read thousands of messages from Indians about what pollution is doing to their lives. What stood out was fear - fear for children, for parents, for tomorrow - felt by families in cities across India. Pollution is no longer just an environmental issue; it is a national health emergency. Parliament must discuss it. The government must act. And this Budget must put real resources behind real solutions. Indians are not asking for reports or rhetoric. They are asking for clean air."
The Budget session will span 30 sittings over 65 days, concluding on April 2. The two Houses will adjourn for a recess on February 13 and reconvene on March 9 to enable the Standing Committees to examine the Demands for Grants of various ministries and departments.
