ANSWER: All of the above

Explanation:

National Green Tribunal has indicated on 10th Nov that when air pollution reaches severe levels, Delhi and neighbouring states will have to take the following measures:

Sprinkling water from choppers

Stopping construction activities

Shutting down polluting power plants and gen-sets

Passing a host of directions to tackling air pollution in Delhi and neighbouring states, the NGT also asked for the setting up of central and 5 state-level monitoring committee to check implementation of orders and form action plans to check pollution

When PM 2.5 and PM 10 levels cross 251 and 431 micrograms cubic metre, it is an environment emergent said the NGT chairperson Swantanter Kumar

The chairperson also said measures would have to be implemented to tackle the situation

Farmers must be given happy seeders-machines that sow wheat without burning paddy residues

This is to prevent crop fires.

During the period of severe air pollution, all construction, transport of construction material and stone crushing activities must be stopped

States will have to shut down power plants, hot-mixers, brick kilns, diesel generator sets whose emissions are above the prescribed limit, according to an interim order for NGT

The NGT also asked 4 neighbouring states of Delhi- Haryana, Punjab, UP and Rajasthan- to consider banning diesel vehicles older than 10 years while directing Delhi to ensure strict implementation of orders on diesel vehicles.

Tribunal also asked Delhi government why they did not install air filters in schools for children as instructed
