Multiple pathways for energy transition would enable countries to choose resources, even coal, while working towards plans on net zero emissions.
Officials said it was the first time India used the phrase 'multiple pathways' in global climate negotiations against repeated demands by Western nations to end coal usage.
At the G20 meeting last month, India kept the focus on fossil fuels, rather than singling out coal, the third official said.
India and China, the world's two most populous countries, have often taken common positions at international climate change negotiations, despite long-standing border disputes.
The G20 includes the G7 countries as well as Russia, China, India, Brazil, Australia and Saudi Arabia, among other nations.
