"Citizens of Delhi must participate in the campaign and also take it beyond an hour and adopt energy saving measures into their daily lives," Jung said.
He especially called upon students to plant more trees, avoid using plastic bags, and concentrate on the three 'R's, i.e. to reduce, re-use and re-cycle.
Jung appealed to the citizens around the world to show their support and join the campaign, which has inspired governments, corporations and individuals, to move towards responsible consumption and conservation of energy.
"It is only when citizens come together and join hands that such campaigns for action against climate change can be successful," Jung said.
The aim of the Earth Hour is to help raise awareness about energy conservation and to pledge commitment to environment. He also urged leading universities and institutions in Delhi to generate awareness about the campaign in their campuses so that students and staff become more environmentally conscious.
Jung said that while climate change is the greatest challenge of our times, it also presents us with an opportunity to help build a greener tomorrow.
The Earth Hour campaign, being run in India since 2009, has received unprecedented support in the past from governments, city authorities, public and private sector companies and individuals.
During the event, millions of people across the globe switch off non-essential lights for an hour. It aims to spread the message, "Switch off this Earth Hour and make the switch to renewable energy".
Around 7,000 cities around the world are expected to take part in the event.
