With experts and Opposition parties questioning the practicability of the scheme in which vehicles with odd and even number registration plates will be allowed to ply on alternate days from January 1, he said many things were yet to be thrashed out including exemption for certain private vehicles.
"In principle, a decision has been taken. Many things are yet to be thrashed out... We will experiment with it for some time. May be for 15 days. If there are too many problems, it will be stopped," he said at the HT Leadership Summit here.
"A sort of panic was created that the pollution has increased so much that something drastic has to be done," he said.
In a radical step to curb air pollution, the city government yesterday announced that private vehicles bearing odd and even registration numbers will be allowed to ply only on alternate days starting January 1.
He said he had thought of introducing such a measure only after taking a number of steps, including redesigning the roads, augmenting public transport by bringing at least 10,000 buses and constructing dedicated elevated roads for buses.
Talking about initiatives taken by his government yesterday to tackle pollution, Kejriwal said vacuum cleaning on all PWD roads will begin from April 1 and grass will be planted on side kerbs and central verges of all the arterial roads to remove dust.
He said tenders will be floated very soon to procure vacuum cleaners from abroad as such machines are not available here. The Chief Minister said Euro 6 emission norms will be implemented in Delhi from 2017 as against Centre's plan to make it mandatory from 2019.
