According to a release of the Ministry of New and Renewable Energy, Javadekar administered an oath of 'non-violence towards environment' to all students.
Speaking on the occasion, Power Minister RK Singh said that the world is facing serious threat from climate change and everyone should take a pledge to leave a better world for future generations.
The release said that over 500 students took part in the effort to create the world record in "environmental sustainability lessons to the largest number of students at one place".
It said that more 5,000 students took part in the "largest number of assembly and lighting of solar lamps".
