Frame rules to regulate indoor air quality in 4 months, NGT tells Centre


Shopping malls, hotels, theatres, educational institutions, office buildings and similar places with public gatherings may soon have to regulate indoor air quality for the safety of their patrons. The National Green Tribunal (NGT), by an order issued on Wednesday, set a deadline of four months for the Union government to frame indoor air quality norms and provide protocols for their regulation.
