Interacting with a group of students from Mumbai at his official residence here, the chief minister also said that Delhi and Mumbai are "not in competition" with each other and he wished both the cities to prosper.
Asked about steps taken to tackle pollution in Delhi, Kejriwal said it is a very complex problem but the AAP government does not lack the political will to take measures to reduce pollution.
"This year, we are planning to plant a large number of trees across Delhi on a war-footing. We will involve school children and citizens also. We are also planning to buy 2,000 buses so that people leave their cars and take to buses," he said.
Grappling with the air pollution crisis in the city, the Delhi government had in December announced that it would procure 500 electric buses which it said would boost the public transport services.
