CAQM Tightens Delhi-NCR Winter Pollution Plan for 2026
The Commission for Air Quality Management updated Delhi-NCR’s winter pollution plan.
Some actions will now begin earlier, during Stage I instead of Stage II.
These actions include controls on diesel generators and inter-city buses.
Rules for certain older vehicles will cover more areas around Delhi.
Large construction sites outside city limits will also face registration and camera-monitoring requirements.
The commission expanded the list of actions citizens are asked to follow from 22 to 34.
It also strengthened checks on dust from construction.
The changes are meant to prepare for worsening air pollution during winter.
CAQM shifted some diesel-generator and inter-city bus measures from GRAP Stage II to Stage I.
Stage III restrictions on BS-III petrol and BS-IV diesel cars now cover Sonipat and parts of three neighboring districts.
Construction and demolition rules now apply beyond municipal limits, including industrial areas, development zones and highway corridors.
Large construction sites of 500 square metres or more must register online and install cameras for video audits.
Citizen-charter measures increased from 22 to 34, alongside stronger dust monitoring across the NCR.

“The GRAP is implemented by CAQM across all of Delhi-NCR and multiple states. Above and beyond, if the state governments want to implement their own pollution curbing measures, they are more than welcome”

“Mostly we have merged and shifted certain repeated measures from stage II to stage I, relating to construction and transport sectors. We have also increased actions in the citizen charter from 22 to 34”
