The announcement came after the air quality in Delhi and the national capital region breached the 'severe' category.

The CAQM, which on Sunday chaired a meeting to review the air quality in Delhi-NCR, put out a release saying, "As the AQI in Delhi has slipped into 'severe' category, the sub-committee had decided that all actions, as envisaged under Stage III of the GRAP, be implemented in right earnest by all the agencies concerned, with immediate effect in the NCR, in addition to all action under Stage I and Stage II of the GRAP."

The panel had further observed that the air quality saw a further deterioration over the last 24 hours, with Delhi's overall Air Quality Index (AQI) at 407 on December 4, according to Central Pollution Control Board (CPCB).

In its order, the CAQM said it temporarily banned construction activities, "with the exception of Metro Rail services, including stations; airport and inter-state bus terminals; railway services/stations; national security/defence-related activities/ projects of national importance; hospitals/healthcare facilities; linear public projects such as highways, roads, flyovers, overbridges, power transmission, pipelines; sanitation projects like sewage treatment plants and water supply projects; ancillary activities specific to and supplementing above categories of projects".
