Ban said the Indian Prime Minister will be addressing the General Debate of the UN General Assembly on September 27, but will not be participating in the climate change summit on Sept 23.
"Even though he will not be able to participate in the climate summit meeting per se, I really wanted to have him (Modi) participate in climate change summit meeting," Ban told reporters here during his briefing ahead of the start of the 69th General Assembly session.
Env Min Prakash Javadekar is expected to represent the country at the summit
Chinese President Xi Jinping and Modi will not be attending the Secretary General's climate change summit, which will be attended by about 120 heads of states and government.
Ban said even though the leaders from India and China will not be able to participate in the meeting, there are "other means of communication" and ways of having the heads of states demonstrate their leadership for the summit.
India's Environment Minister Prakash Javadekar is expected to represent the country at the summit, which will focus on mobilising political will for a universal and meaningful climate agreement next year in Paris and second to generate ambitious steps to reduce greenhouse gas emissions and strengthen resilience.
