India on Friday said developed nations have not fulfilled their promise on the issue of transferring technology to developing countries to meet carbon emission goals.

Environment Minister Jayanthi Natarajan said developed nations were hesitant to vow for such a step during discussions on climate change-related issues.

“The transfer of technology is the most important issue. And developed countries took the responsibility under the Montreal Protocol, which has not yet happened under other discussions that we are having,” she said, while addressing International Ozone Day celebrations in New Delhi.

She said the widely ratified Montreal Protocol dealing with the issue of ozone layer depletion could serve as a model of global cooperation while addressing serious environmental concerns.

Ms. Natarajan’s remarks came a day after she made it clear that India will press for developed nations to agree to a second commitment period of the Kyoto Protocol on reduction of greenhouse gas emissions in the Durban conference on climate change later this year.
