New Delhi: After the Centre denied him the permission to attend C40 Climate Change Summit in Copenhagen, Denmark, Delhi Chief Minister Arvind Kejriwal will address the session on Friday through video-conferencing on the steps to tackle air pollution. He will also address a joint press conference of seven cities.

"On the request of the C40 Copenhagen organisers, I will join the Summit over video. Will address a PC with Mayors of the world's megacities to launch the Clean Air Declaration," Kejriwal tweeted, adding that he will also share Delhi's story of fighting pollution at the 'Breathe Deeply' session.
