He also permitted construction activities only during the daytime from 6 AM to 6 PM due to poor dispersion of pollutants at night.

Environment Protection Control Authority (EPCA) Chairman Bhure Lal, in a letter to chief secretary of Delhi, Haryana and Uttar Pradesh said the vehicle sticker has not been implemented and without this it is not possible to distinguish between diesel and other fuelled vehicles. He said that implementing the ban would be hard as it is not possible to distinguish between diesel and other fuelled vehicles.

On Wednesday, the PM2.5 - particles in the air with a diameter of less than 2.5 micrometres - level was recorded at 175, while the PM10 - particles in the air with a diameter of less than 10 micrometres - was recorded at 280 in Delhi, according to the data by the Central Pollution Control Board. "Only those vehicles that drive using a CNG fuel will be allowed so that pollution level can be checked", Added Lal. It also said heavy vehicles stationed at the Delhi border will not be charged any toll tax till Tuesday.

"We have directed for removal of (the) environment compensation charge and toll so that there is no congestion on the entry points and that the accumulated trucks can enter", he said.

Stubble burning accounted for just three per cent of Delhi's air pollution today, the lowest for this month, according to a government agency.

Twenty one areas in Delhi recorded "very poor" air quality while 14 areas showed "poor" air quality, the CPCB said.

The impact of PM 2.5 (particles in the air with a diameter of less than 2.5 micrometres) in the pollution has been marginal in the last couple of days as stubble burning in the neighbouring states declined significantly.

An AQI between 0 and 50 is considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor" and 401 and 500 "severe".

According to the Centre-run System of Air Quality and Weather Forecasting (SAFAR), the contribution of stubble burning to the pollution in Delhi has been recorded the least on Wednesday for this month at 3 per cent.
